Black Jewelry in Sterling Silver  

Black Gemstones Set in .925 Silver: Onyx to Obsidian

Black gemstones have served both decorative and symbolic purposes across cultures for thousands of years. Black onyx, mined in Brazil, India, and Uruguay, forms when silica-rich waters deposit layers within volcanic rock cavities. This slow process creates the stone's characteristic solid black color and smooth polish potential. Obsidian, by contrast, forms rapidly when volcanic lava cools before crystals can develop, resulting in natural volcanic glass that ancient civilizations shaped into tools and jewelry. Black tourmaline, also called schorl, contains iron that gives it dark coloration and accounts for roughly 95% of all tourmaline found in nature. With a Mohs hardness of 7-7.5, it resists scratching better than many colored stones. Our sterling silver settings use 92.5% pure silver alloyed with copper for durability, a standard maintained in jewelry making for centuries. SilverRush Style has offered natural stone jewelry since 2005. Browse black rings, pendants, earrings, and bracelets at various price points. Each piece pairs dark stones with bright silver to let the metalwork complement rather than compete with the gemstone.
