Black Necklaces in Sterling Silver  

Natural Black Gemstones Set in .925 Silver Since 2005

Black gemstones occur across multiple mineral families, each with specific characteristics worth knowing. Black onyx forms in the chalcedony family and takes a high polish that resists scratching. Black spinel, often mistaken historically for other dark stones, rates 8 on the Mohs scale—harder than most colored gems. Obsidian contains no crystal structure, which gives it that characteristic glass-like sheen and conchoidal fracture pattern. Our sterling silver settings use 92.5% pure silver alloyed for durability. The contrast between polished silver and matte or glossy black stones creates clear visual distinction without competing elements. Pendant sizes in this collection range from understated 10mm cabochons to statement pieces with multiple stone arrangements. SilverRush Style has sourced natural gemstones since 2005. Prices in this collection run from $479 to $38,569, reflecting stone size, quality, and setting complexity. Browse the full range to find black necklaces that match your specifications.
