The Co-op Guarantee

Thirty years ago, a group of passionate, dedicated vendors and friends decided to start their own show. The Mineral and Fossil Co-op, affectionately known as “The Co-op”, became Tucson’s first permanent show in what is now the heart of Tucson’s mineral and fossil district (on N. Oracle Rd between Drachman St. and Grant Rd.). Members are voted in and own a unique gallery space. Ralph Thompson, of founding member Russell-Zuhl, looks for “dealers that have a life-long commitment to showing the finest specimens in their class.” The vetting process guarantees the quality, variety, and selection of minerals and fossils curated by members. Co-op members offer specimens from around the world, each bringing their own specialty and expertise. The Co-op remains Tucson’s only show of vetted owner members. 

Stephen Bruce

Stephen Bruce is a California-based abstract artist known for his distinctive acid paintings on copper. Using a technique he began developing in 2003, Bruce applies acids and other reactive materials to copper, accelerating oxidation to create richly colored, organic surfaces shaped by artistic intention and natural chemical processes. Inspired by what he calls the greatest artist, Mother Earth, his abstract compositions echo the colors and patterns of geological formations, while his seascapes and landscapes evoke aerial ocean views and fleeting moments along the horizon. His work balances luminous color, atmospheric depth, and the unpredictable character of the metal.

Karyn Holyk

Crystal Alchemist and Artist

"Gemstones lead the work. I follow."

Karyn Holyk is a Tucson-based Crystal Alchemist, artist, and instructor who creates watercolors from hand-ground gemstones, crystals, and precious metals. Her lifelong connection to stones and minerals led her to reclaim one of our most ancient practices, using the earth itself as pigment, resulting in luminous, semi-abstract works that carry both color and energetic resonance. As much a creative wellness practice as a fine art discipline, her work explores the power of creativity to expand what we believe is possible in ourselves. She teaches workshops, offers gemstone paint kits, and curates the work of minral and metal based artists throughout the region.
