Catalog Search Guide
You can search our catalog using different mineral attributes. For example, you can search by color such as green, yellow or purple, or by chemical elements such as uranium, calcium or iron, or by mineral groups such as phosphate, silicate or carbonate. You can also filter by crystal habit like crystal, geode or crystal on matrix, by specimen size such as thumbnail, small, medium or cabinet, and by features such as radioactive or fluorescent minerals.
United States
Discover a world-class collection of mineral specimens from the United States, one of the most diverse and historically important mineral-producing countries globally. The USA is famous for producing some of the finest collector minerals ever found, spanning hydrothermal veins, carbonate deposits, pegmatites and classic mining districts.
Key localities include Colorado (Sweet Home Mine, famous for rhodochrosite), Illinois (fluorite districts such as Cave-in-Rock), Arizona (Bisbee, Morenci, Red Cloud Mine), Utah (Topaz Mountain), New Mexico, Nevada and the Appalachian mining regions. Franklin and Sterling Hill in New Jersey are world-famous for an extraordinary diversity of fluorescent minerals, including vivid willemite, franklinite and zincite, found nowhere else on Earth in such variety.
This collection features highly sought-after minerals such as rhodochrosite (Sweet Home Mine, Colorado), fluorite (Illinois, Colorado and other classic districts), galena, sphalerite, wulfenite, vanadinite, barite, calcite, quartz varieties including terminated "Herkimer diamonds" from New York State, rare benitoite (California's official state gem), and garnet.
The United States is also globally significant for uranium and secondary uranium minerals, with classic occurrences in Colorado Plateau districts and historic mining areas, producing specimens valued for both scientific importance and intense fluorescence.
US minerals are especially prized for their sharp crystallization, bold colors and iconic worldwide localities. From deep red rhodochrosite crystals to cubic fluorite, metallic galena and sphalerite associations, and vibrant secondary uranium minerals, this collection represents some of the most recognizable and desirable mineral species in modern collecting.
