Montana Agate Jewelry in Sterling Silver  

American Gemstone Patterns Formed Over 50 Million Years

Montana agate forms in the alluvial gravels along the Yellowstone River and its tributaries in southeastern Montana. Collectors prize these stones for their landscape-like scenes: dark dendrite patterns that resemble trees, mountains, or prairie grass suspended in cream, gray, or pale orange chalcedony. No two stones share the same internal picture, which is why lapidaries select each piece for its individual character before cutting. The geological conditions that created Montana agate no longer exist, making the supply finite. Rockhounds and commercial collectors gather these agates from river deposits where erosion continues to expose new material each season. Our sterling silver settings protect the polished cabochons while letting the natural artwork remain visible from multiple angles. SilverRush Style has offered natural stone jewelry since 2005. We photograph each piece so you see the actual stone you will receive. If you want an American gemstone with genuine regional character, consider adding a Montana agate ring or pendant to your collection.
