Nearly 2 decades of great shows
Meet the Owners
Russell & Missy Carhart have been in the Gem business for 2 decades.
At Hart Gem Shows, we believe the greatest treasures aren’t just the extraordinary gems, minerals, fossils, jewelry, and artisan creations found throughout our shows—they’re the people who make our community so special.
For decades, Hart Gem Shows has been more than a place to buy and sell. It’s where lifelong friendships are renewed, new connections are formed, knowledge is shared, and generations of collectors, dealers, artists, and enthusiasts come together to celebrate a shared passion.
Every show is built on one simple philosophy: when you walk through our doors, you’re family.
A Tradition of Connection
Owners Missy and Russell Carhart have spent their careers creating world-class gem shows that foster meaningful relationships as much as successful business.
Many of our exhibitors and attendees have been part of the Hart Gem Shows family for years—even decades. They travel from across the United States and around the world not only to showcase remarkable collections but also to reconnect with friends who share their passion for the gem and mineral industry.
Whether you’re a first-time visitor or a longtime exhibitor, you’ll quickly discover that Hart Gem Shows offers something unique—a welcoming community where conversations begin with stories, friendships last a lifetime, and everyone shares in the excitement of discovery.

Hart Gem Shows proudly produces four of North America’s premier gem, mineral, fossil, jewelry, and bead events:

The New Jersey Gem Show – Fall – Edison, New Jersey
Together, these internationally recognized events welcome thousands of collectors, wholesalers, retailers, jewelry designers, lapidary artists, museums, educators, students, and families from around the globe.
Whether you’re searching for rare minerals, fine gemstones, handcrafted jewelry, fossils, beads, crystals, or one-of-a-kind treasures, Hart Gem Shows brings together an unmatched selection of exhibitors in an atmosphere that celebrates education, exploration, and community.

A Global Presence

Each year, the Carharts strengthen relationships with exhibitors, museums, collectors, and industry leaders by participating in many of the world’s premier mineral and gem exhibitions.
As a proud sponsor of the renowned Sainte-Marie-aux-Mines Mineral & Gem Show in France and a regular participant at The Munich Show in Germany, Hart Gem Shows continues to build partnerships that connect the global marketplace with collectors, businesses, and enthusiasts throughout North America.
These international relationships help introduce new exhibitors, fresh discoveries, emerging trends, and extraordinary collections to every Hart Gem Show.
Inspiring the Next Generation
Education is at the heart of everything we do.
Our Kids Zone offers hands-on experiences that introduce children to gems, minerals, fossils, dinosaurs, and Earth science in fun, interactive ways designed to spark curiosity and inspire future collectors, geologists, jewelers, and scientists.
Families are encouraged to spend the day exploring together, creating lasting memories while discovering the incredible stories hidden within the Earth’s natural treasures.
The Denver Gem Show is proud to partner with organizations including Little Man Ice Cream, Dinosaur Ridge, and M&M Concessions to provide engaging educational experiences for young visitors.
By inspiring curiosity today, we’re helping cultivate the next generation of collectors, educators, scientists, and industry leaders.
More Than a Show
Hart Gem Shows has earned a reputation for producing exceptional events—but our purpose goes far beyond hosting successful exhibitions.
We believe in building relationships, supporting our exhibitors, educating future generations, strengthening local communities, and creating unforgettable experiences for every person who walks through our doors.
For many, attending a Hart Gem Show has become an annual tradition. It’s a place where lifelong friendships are renewed, remarkable discoveries are made, businesses grow, families create memories together, and the global gem and mineral community gathers as one.
