5/11/2026 Older Than a Fossil, And Farther From Home Than A Meteorite: The Life Of A Science Adventurer...By Geoffrey NotkinRead NowOlder Than a Fossil, And Farther From Home Than A Meteorite: The Life Of A Science Adventurer By Geoffrey Notkin  Geoff Notkin Portrait Ever since I was a kid, I have been fascinated by ancient things. Some children collect sports cards or toy roots, but I collected rocks, fossils, and weird natural history objects that seemed as if they might hold a secret about our world or, indeed, a different world. Looking back now, I realize that innate curiosity became the foundation of my entire life. Whether I was searching for meteorites that traveled through space for billions of years, or fossils that preserved life from Earth’s distant past, I was always searching for pieces of history — a very ancient history. I was born in New York City, but grew up in England, the son of Foreign Service parents. London in the 1960s, and the rolling chalk hills (full of Cretaceous fossils) to the south, were perfect places to encourage and cultivate my early love of science and exploration. By the time I was six or seven, I was completely obsessed with astronomy, geology, paleontology, and natural history, and since my overly strict British public school did not offer any of those subjects, I became expert at “bunking off” [skipping school] and digging in the local quarry instead. Thanks to my mother's patience, I visited museums frequently — especially the Natural History Museum in London — spending hours staring at ichthyosaur skeletons, gorgeous, colorful minerals, and meteorites displayed in vintage glass cabinets. To me, those objects were not just scientific specimens—they were time machines. Fossils told stories about life on Earth millions of years ago, while meteorites told stories about the formation of the solar system itself.
As I grew older, my interests expanded beyond science alone. I studied fine art, design, writing, and photography because I was fascinated by how we share information through written and visual communication and storytelling. Science is full of wonder, but scientific presentation is often presented in ways that feel distant or intimidating to the public (or, dare I say, dull?). I wanted to change that. Science can be exciting, emotional, and adventurous, and everyone should have the chance to feel the thrill of discovery. For many years, meteorites were my primary focus. The first time I held a real one in my hand, I experienced something almost impossible to describe. Here was a rock older than Earth itself—a fragment of another world that had survived a violent journey through space and landed on our planet. It felt mysterious, ancient, and deeply meaningful. That moment changed my life. I founded a small business, literally in my garage. Today, that business — Aerolite Meteorites, Inc. — is no longer small; it is the world leader in the field of meteorite collecting and commerce. I began studying meteorites seriously, learned how to identify them, value them, and search for them in the remotest of landscapes, from the Sahara Desert and the Australian Outback, to Siberia and the Arctic. Meteorite hunting is a sometimes-baffling combination of science, patience, strategy, intuition, and luck. Some days or, in fact, some weeks, you hike for miles and miles beneath a relentless sun with no success at all. Other times, a dark, odd-looking shape at the bottom of a dig hole makes your heart jump, and suddenly you are holding a piece of cosmic history. But while meteorites became central to my career for many years, I never lost my passion for paleontology. Fossils enthrall me for the same reasons. A fossil, like a meteorite, is a messenger from another time. Whether it is the leg bone of a dinosaur, the shell of a beautiful ammonite, or the imprint of an ancient plant, each fossil captures and preserves a moment from Earth’s long and complicated history. Both require finding, careful observation, scientific analysis, and imagination. Both tell stories about worlds that existed long before human civilization. And both inspire wonder, too. I became increasingly involved in the paleontological community and have had the privilege of working alongside collectors, researchers, educators, and museums that share a passion for preserving and studying fossils. I formed the Notkin Rock & Fossil company as a separate business, but with the same core principles as Aerolite — a dedication to authenticity, accurate description and identification, and — thanks to my degree in media arts — elegant presentation. And my active involvement with the Association of Applied Paleontological Sciences (AAPS) for over 25 years reflects my belief that ethical fossil collecting and scientific cooperation are not only important, but vital if we are to continue moving the chess piece of knowledge further across the board. Today, I am honored to serve as AAPS President. I strongly believe that science should not exist only inside laboratories and universities. Ordinary people can, and do every single day, contribute to scientific discovery. Responsible fossil and meteorite hunters have, countless times, made critically important finds that advance scientific understanding. Some discoveries that once lived in private collections later become part of museum exhibits and academic research collections. I have personally donated important pieces to museums all over the world.
A similar philosophy influenced my television work. Many people know me from the television series “Meteorite Men,” in which my colleague Steve Arnold and I traveled the equivalent of five times around the globe, searching for space rocks. The show was an international hit, airing on all seven continents, and introduced audiences to the mystery and excitement of meteorites. But, for me, it was more than a treasure hunt. It was about curiosity and about showing viewers that science can be adventurous and accessible. Nobody was more surprised than I at the success of the show. I knew people at gem shows were interested in the chance to hold a space rock, but I did not imagine that viewers around the world would become so caught up in the science of the hunt. Suddenly, people who had never thought about meteorites started collecting them; untold numbers of new meteorites were discovered and identified; teachers used clips from the program in classrooms; families visited science museums because they had seen the show together. And — this is the best part — some of the kids who were fans today hold doctorates in meteoritics, archaeology, astronomy, and other disciplines.  Meteorite Men logo © LMNO Productions Through my books, articles, public speaking, television appearances, and educational outreach, my goals have always been to make science feel alive and personal. I wrote about meteorites, paleontology, astronomy, history, and exploration because I hoped others would feel the way I do — science is not simply a collection of facts, it is an amazing journey.
In the end, what drives me is wonder. When I am at the top of a mesa, far out in the desert, looking for dinosaur bones, I sometimes think about how minuscule we are in comparison to the engine of time. And yet, despite our smallness, we have miraculous abilities: we can ask questions, investigate mysteries, and find answers inside rocks, fossils, and fragments of other worlds. Part of the lonely, curious little boy wandering through museums and staring at the stars is still with me. The difference is that now I have the great good fortune to turn that curiosity into a career — one that combines science, storytelling, adventure, and education. When I find a fossil that shows us an impossibly old snapshot of life from Earth’s ancient oceans, I feel the same sense of awe I felt as a kid. Both remind me that our planet and our universe are filled with stories waiting to be discovered. And those stories belong to all of us. Images © Desert Owl Productions, Inc.

4/6/2026 Talk Rocks with Leonard Himes at This Year’s Colorado Mineral & Fossil Spring ShowRead NowTalk Rocks with Leonard Himes at This Year’s Colorado Mineral & Fossil Spring Show By Rachel Ford  Leonard Himes in his labratory prepping mineral specimens. For Leonard Himes, a lifelong passion for minerals began in an unlikely place, central Florida. Where, as he puts it, "rocks don't really exist." What started as a childhood curiosity has grown into decades of collecting, teaching, and contributing to the mineral community. Today, Leonard is a familiar and respected presence at shows across the country, and attendees of the upcoming Colorado Mineral and Fossil Spring Show can look forward to both his knowledge and his carefully curated specimens, inspiring others to follow their passions. I asked Leonard to tell me where his love for minerals first began. He traces his interest back to the 5th grade, when he and his friends discovered mineral material dredged from the St. Johns River: gemmy yellow calcite crystals and fossil clams. "That was exciting stuff," he recalls. Likely, after bringing the specimens in for show-and-tell, his teacher encouraged Leonard and another classmate to begin studying the minerals and to share what they learned. This other classmate's grandmother's collection would be Leonard's first exposure to mineral collecting. Leonard, now "hooked," began receiving mineral souvenirs after his well-traveled aunt learned of his passion. Living in a region with limited natural mineral diversity did not slow him down. Leonard began writing letters to geological surveys across the country, requesting samples. Some responded with thoughtfully prepared collections, opening his eyes to the broader world of mineralogy. Later in the 7th grade, his teacher, who also had an interest in minerals, had catalogs for Wards Natural Science Establishment. Interested kids, like Leonard, could contribute their nickels and dimes and choose pieces from the catalog. Leonard recalls, "It was really fun when the package arrived, and we saw the rocks. Looking back, he credits Mrs. Richard & Miss Boyle's encouragement for leading him on a career in teaching.
Leonard stepped away from collecting during college, where he studied chemistry and earned a teaching certificate. The passion returned in full force when a fellow teacher, Edwin Allabough, introduced him to the world of mineral shows and field collecting. This introduction changed everything. Now married, family vacations soon became collecting trips, including time spent at the well-known Ruggles Mine in New Hampshire. What began as a hobby quickly evolved into something more after selling off the Autunite he found there. Leonard discovered he could sell what he collected, eventually building a business that supported him through the summers and ultimately grew into his becoming a nationwide retail mineral dealer. While Leonard is often associated with Colorado minerals, particularly from Ouray County, he is quick to emphasize that he does not consider himself a specialist. Still, his experiences collecting in the San Juan Mountains left a strong impression. "It's a wonderful scenic area," he says. "Great for trout fishing and jeeping on mountain roads." For Leonard, places like Ouray and Silverton represent more than mineral localities. They are landscapes that combine natural beauty with the thrill of discovery. One of Leonard’s most memorable finds came from a wavellite pocket in Avant, Arkansas, in the early 1970s. The specimens he recovered were significant enough to be acquired by both the Smithsonian Institution and the American Museum of Natural History, an achievement that also helped launch his business. At his core, Leonard remains an educator. "I am a career teacher, so it is simply part of who I am," he explains. "I cannot help but help people." That mindset has made him a valuable resource within the mineral community. Whether speaking with new collectors or seasoned enthusiasts, Leonard sees education as essential to preserving the integrity of the field. "Knowledgeable collectors and dealers have a responsibility to share accurate information and correct misunderstandings," he says. For those just starting, his advice is simple but important. Join a local mineral club, learn from experienced collectors, and invest in good books.
For Leonard, mineral shows are about far more than buying and selling. "The best part is the people," he says. "Meeting new customers and reconnecting with old friends." That sense of community is something he has experienced throughout his career, and it remains one of the most rewarding aspects of being part of the mineral world. At this year's Colorado Mineral and Fossil Spring Show, Leonard will be offering something especially meaningful: pieces from his own long-held inventory. "As I begin to reduce my inventory, I am rediscovering high-quality specimens that are no longer in current production," he explains. "Many of these may be new to younger collectors." Attendees at the Colorado Mineral & Fossil Spring Show can expect to find these pieces offered at discounted prices, along with standout specimens, including exceptional gem-quality forsterite (peridot) from Pakistan, among the finest he has handled.
With a lifetime of experience, a deep commitment to education, and a genuine appreciation for the people who make up the mineral community, Leonard Himes brings something truly special to every show he attends. His story is a reminder that sometimes, all it takes is a small discovery and a little encouragement to spark a lifelong journey.
Visit Leonard Himes in Booth #33 to "talk rocks" at the Colorado Mineral & Fossil Spring Show, located in the new Livestock Center at the National Western Center. The show is located at 4850 National Western Drive in Denver, Colorado, and will run from April 17-19, 2026. It includes free admission and is open daily from 10-6. On Sunday, the 19th, it will close at 4 pm. 1/16/2026 Don't Miss Out on the Opportunity for Adventure with Ivan Pojarevski at the 2026 RMGM Tucson Mineral & Fossil Tent ShowRead NowDon't Miss Out on the Opportunity for Adventure with Ivan Pojarevski at the 2026 RMGM Tucson Mineral & Fossil Tent Show By Rachel Ford At the 2026 RMGM Tucson Mineral & Fossil Show, collectors and enthusiasts will have an opportunity to meet a scientist whose passion for minerals extends far beyond display cases and into the very heart of their geological formation. Ivan Pojarevski, a retired mineralogist and Honoured Doctor in Gemology of the Balkan Academy of Sciences, will be exhibiting in Booth 6A with material from his company, Bulgarian Gems & Minerals Co. Pojarevski, now retired, has spent more than 45 years studying minerals through the study of crystal morphology. Crystal Morphology is the external shape, form, and growth pattern of a crystal, determined by its internal atomic structure and influenced by growth conditions like temperature, pressure, and additives, resulting in characteristic features like faces, edges, and angles that dictate its physical properties. "I am not a collector in the traditional sense," Ivan explains, "but a researcher who has spent decades assembling minerals to understand their formation and history." Pojarevski's lifelong curiosity has taken him deep underground and across the surface of mineral localities in Bulgaria and its surrounding regions, always driven by the scientific mysteries locked in stone.
Collectors and Resalers visiting Booth 6A will see firsthand the unique specimens that have been the focus of Pojarevski's research and discuss them with Ivan himself, who knows the specimens inside and out. Among these are rare and stunning examples of galena with dramatic skeletal and cascading growth, rare sparkling orange thulite, highly aesthetic rainbow chalcopyrite, and a newly discovered transparent green sphalerite. The highlight of Bulgarian Gems and Mineral Co.'s exhibit this year is a truly extraordinary ruby crystal from North Macedonia, weighing 2.6 pounds and exhibiting an elegant hexagonal form. This exceptional ruby specimen will be part of a rather exclusive lot of ruby crystal specimens. What truly sets Bulgarian Gems and Minerals Co. apart from other exhibitors is not just the material Pojarevski brings to shows; it is the story of the specimens' discovery and the experiences he offers others who wish to discover that story for themselves. About fifteen years ago, Ivan began inviting mineral enthusiasts to join him in the field on what he calls "collecting tours" aimed at "the curious people who like adventures, minerals, and gemstones." "My interest is always in research, and I need new specimens to study," he says. Out of that need grew a series of guided mineral-collecting adventures through Bulgaria and now into North Macedonia. These are not your typical itineraries or pre-set tourist outings. Pojarevski tailors each tour to individual participants' interests, preferences, and physical abilities. Whether a participant is a seasoned collector or someone who has never held a geological hammer, Ivan designs the tour for his participants.
Over the years, Ivan has led 46 successful excursions with participants from 14 countries, exploring abandoned underground mines and diverse surface-collecting localities. "Each journey has yielded significant finds of galena, sphalerite (including black marmatite and transparent cleophane), pyrite, rhodochrosite, pink manganocalcite, quartz, and gemstones such as amethyst, opal, and varieties of agate and jasper," says Pojarevski. Collectors on these tours do more than gather specimens; they learn the science behind them as Ivan explains what makes each piece unique and how geological processes have shaped it over millions of years. "Part of my hobby," he says with a grin, "is to explain and discuss with people how and why the minerals look the way they do, and what their specific history is." Pojarevski curates more than just collecting trips; these tours are immersive opportunities to see geology in action, to learn from a lifetime of study directly in the field, and to connect with like-minded explorers who cherish both adventure and understanding. In addition to the educational aspect of the tours, participants enjoy the local landscape, visit historical and archaeological sites, and enjoy the balanced flavors of traditional Bulgarian food and drink. Participants are encouraged to immerse themselves in the culture that shapes the people of the landscape.
For showgoers at Tucson, meeting Ivan at Booth 6A will be an experience beyond the typical dealer interaction. It is the opportunity to encounter someone whose life's work bridges science and exploration, someone who finds joy not in owning specimens (he is not a collector, he admits), but in a unique passion for understanding them and sharing that understanding with others. Whether you come to admire the exceptional specimens he brings, to hear the stories behind them, or to ask about joining one of his upcoming tours, Ivan's booth promises to be a destination for anyone who loves minerals, adventure, and discovery . The RMGM Tucson Mineral & Fossil Tent Show runs daily from January 30 through February 14 in the Tent Show at 1920 N. Oracle Road in Tucson, Arizona. Hours are 10 - 6 daily, with the final day closing at 4. Admission and parking are free, food trucks are on-site, and the event continues RMGM's tradition of bringing together quality vendors and world-class materials for a family-friendly celebration of minerals, fossils, gemstones, meteorites, and more.

Jim was a pioneer and one of the first collectors to participate in the Tucson Gem & Mineral Show. The Tucson Gem & Mineral Show, the core of the larger Tucson Gem, Mineral & Fossil Showcase, started in 1955 as a small club event by the Tucson Gem & Mineral Society (TGMS) (rockhounds) in a school cafeteria, growing from 15 vendors to the largest gem and mineral event in the world, hosting over 40 independent shows annually.
In 2019, after a colon cancer diagnosis, Jim sold the family business to his son, Rob Tynsky (4th-generation fossil collector/preparer), who grew up working in the quarry and preparing fossils, and to his wife, Kodi (daughter-in-law). He continued to live out his days digging and prepping fossils until his death on December 3, 2025. Jim was an instrumental member of the fossil collecting and preparation community as we know it today. His talent, wit, humor, and passion will be greatly missed. His presence and absence have forever changed the mineral and fossil community.

Rob and Kodi purchased the business with the intention of continuing the family legacy and carrying it forward for future generations. Today, Tynsky’s Fossils operates both a fossil gallery and an active quarry experience, offering the public hands-on access to Eocene-age fossils from Fossil Lake, one of the most significant freshwater fossil deposits in the world. Visitors can excavate and keep their own fossils while learning directly from a family with expertise spanning more than six decades. Through education, ethical quarrying practices, and public engagement, Tynsky’s Fossils continues to connect people with prehistoric life while preserving a deeply rooted family tradition in paleontology. ¹
That commitment to education, accessibility, and respect is something I have experienced personally. My son began collecting fossils at a very young age, digging them himself, learning to prep them, and selling minerals and fossils he dug and purchased for resale at shows across the country to build a serious personal collection. Throughout those formative years, the Tynskys were consistently approachable and generous with their time and knowledge. They treated my son, even when he was just nine years old, as a valued customer and fellow enthusiast rather than dismissing him as “just a kid.” Anyone who has spent time in this business or hobby understands how much that level of respect truly says about a company.

By Rachel Ford
At the 2026 RMGM Tucson Mineral & Fossil Show, collectors and mineral enthusiasts will have the rare opportunity to witness one of the most extraordinary native silver discoveries ever documented. Dr. Chris Osterman will present his findings from a modern rediscovery of Arizona’s legendary silver heritage, which bridges deep geological history, frontier lore, and cutting-edge mineral exploration.
Dr. Chris Osterman’s path to this discovery is grounded in rigorous science and decades of field experience. Trained initially as a mining engineer (BSc Mining Engineering - U of Idaho), Osterman went on to earn advanced degrees (MSc Geological Engineering - U of Arizona) in geology, culminating in a PhD in Geology from the Colorado School of Mines, focusing on sediment-hosted copper deposits in Namibia. His career, spanning over 30 years, has been defined by a rare combination of technical expertise and an instinct for identifying geological anomalies that others might overlook.

His career, spanning over 30 years, has been defined by a rare combination of technical expertise and an instinct for identifying geological anomalies that others might overlook.
That instinct led him to Globe, Arizona, after a friend tipped him off to unusual silver finds in the area around 2019. What began as scattered reports from a group of metal detectorists quickly evolved into one of the most significant native silver discoveries of the modern era. The first breakthrough came when some local metal detectorists uncovered a 16-pound native silver nugget affectionately nicknamed “The Sweet Potato.” This initial rediscovery confirmed suspicions that something extraordinary lay beneath the surface.
Over the following two years, nearly 200 pounds of native silver were recovered in roughly two dozen pieces, ranging from a few grams to astonishing specimens weighing up to 120 pounds. Recognizing the significance of the find, a deal was struck to purchase and stake a claim to the property. The local metal detectorists, uninterested in traditional lode mining, stepped aside, clearing the way for what would become known as the 417 Project, named after the largest nugget ultimately recovered.
The project’s primary goal was ambitious and clear: to locate the source vein—the long-sought “motherlode” responsible for these massive silver deposits.
Record-Breaking Native Silver Specimens
The silver recovered from the 417 Project is remarkable not only for its size, but for its form. These are not delicate wire silvers, but massive, crystalline native silver nuggets, often associated with smoky quartz. Among the most notable specimens:

Record-Breaking Native Silver Specimens
The silver recovered from the 417 Project is remarkable not only for its size, but for its form. These are not delicate wire silvers, but massive, crystalline native silver nuggets, often associated with smoky quartz. Among the most notable specimens:
- 417.8 lb nugget – the largest intact native silver nugget known in the world
- 116 lb nugget
- 86 lb nugget, split down the middle, widely regarded as the most visually striking due to its crystalline structure and classic silver appearance
The 86-pound split specimen, in particular, shows silver tarnish on the exterior while retaining remarkable internal luster. Collectively, these specimens redefine what many believed possible for native silver formation. Dr. Osterman has described the discovery succinctly: “It’s a one-in-a-billion chance of finding something like this. It is very unique, it’s just not found.”
To enhance the silver’s natural luster, the specimens were professionally treated by Brian Lees using hydrofluoric acid, a specialized process that removes surface oxidation and reveals the metal's brilliance. Since then, many of the largest nuggets from the 417 Project have been on loan to the University of Arizona’s Alfie Norville Gem & Mineral Museum, where they have drawn significant attention from both scientists and the public.

For the 2026 RMGM Tucson Show, Dr. Osterman will debut newly fabricated custom display stands, allowing these specimens to be exhibited and offered for sale in a show setting for the first time. In addition to the museum-grade pieces, approximately 200 native silver nuggets from the discovery will be available, along with over 200 lapidary slabs cut from the silver, cabochons, freeform polished nuggets, and jewelry crafted directly from the discovery, featuring set cabochons and natural silver forms.
Globe, Arizona: Silver Legends Reawakened
The discovery also reconnects Globe to its origins as a silver district. Historical accounts suggest that 500-pound silver nuggets were discovered in the area in the late 19th century, though many were smelted down and lost to history. Local legend holds that Apaches were among the first to work native silver in the region during the 1870s, smelting it to make bullets, an origin story often cited as the root of the “silver bullet” legend later popularized in American folklore.
The Richmond Basin, part of the broader Arizona Silver Belt, played a critical role in this history. Early prospectors followed alluvial silver washes upstream to locate lode deposits, establishing mines such as McMorris, La Plata, Helena, and Silver Sevens. As silver prices declined and copper rose to dominance, many of these high-grade silver districts were abandoned, until now.

The Search Continues… Although the property was sold approximately two years ago to Silver One Resources, whose exploration focus is on massive silver deposits, the 417 Project's mission continues. The ultimate objective is still the same: to fully define and understand the source vein responsible for one of the most significant native silver discoveries ever recorded.
For collectors, historians, and geologists alike, the 417 Project is more than a find; it is a rediscovery of Arizona’s silver legacy, brought vividly back to life.

Ammolite is among Canada’s rarest and most extraordinary gemstones. It is found exclusively in the Bearpaw Formation, located along the eastern slopes of the Canadian Rockies. This gemstone forms from the fossilized shells of Ammonites, marine creatures that lived approximately 71 million years ago.
What makes Ammolite truly unique is its vibrant, natural iridescence. Colors range from fiery reds and vivid greens to shimmering golds, and in the rarest specimens, deep blues and purples. This rich palette is the result of the microscopic aragonite layers within the shell, a structure that interacts with light to create a mesmerizing play of color.
Beyond its scientific and aesthetic wonder, Ammolite holds profound cultural significance. For generations, the Blackfoot people have known this gem as Iniskim, or “Buffalo Stone.” It has been cherished not only for its beauty but as a sacred symbol of prosperity, guidance, and protection. Ammolite’s connection to Indigenous traditions adds a vital dimension to its story—one that KORITE proudly honors through Indigenous ownership and responsible stewardship.
Because of its rarity and cultural importance, Canadian Ammonites and Ammolite remain unlike any other fossil or gemstone. They are valued by collectors, jewelers, and connoisseurs around the world for their beauty, story, and connection to Canada’s natural and cultural heritage.
Returning under new Indigenous and female-led ownership and leadership, the company will, for the first time, exhibit with the Colorado Mineral and Fossil Fall Show.

Leadership That Comes Full Circle
For Amarjeet Grewal, KORITE’s President and co-owner, Ammolite has been a lifelong passion. She began her career with KORITE nearly 35 years ago, building a reputation as one of the most knowledgeable and respected voices in the Ammolite industry. Over the decades, she developed strong relationships with global partners, led major trade show appearances in markets such as Hong Kong and Tucson, and played a pivotal role in elevating Ammolite’s position in international markets.
In time, Amarjeet branched out to create and lead her own successful Ammolite brand, introducing the gemstone to new audiences worldwide while maintaining a deep respect for its cultural and natural origins. Now, she returns to lead the very company where her journey began—bringing with her decades of expertise, a global vision, and a commitment to sustainable, ethical growth.
This new chapter is also historic for another reason: for the first time, KORITE is Indigenous-owned. Amarjeet shares ownership with Beth and Tracy Day Chief, members of the Blood Tribe (Kainai Nation) and respected owners of Buffalo Rock Mining, responsibly mining Ammonites since 2008. Their deep roots and cultural connection to Ammolite bring KORITE’s story full circle.
