Onyx Gemstone Bracelet 18 mm

Mineralogically, onyx is a variety of chalcedony (microcrystalline SiO₂), with a Mohs hardness of 6.5–7 and a trigonal crystal system. Its deep, rich black color is created by natural carbon inclusions or enhanced through dyeing. The name comes from the Greek "onyx" (fingernail). In antiquity, onyx was used for signet rings and cameos and was considered a protective stone for warriors. The large 18 mm beads showcase this deep black as an expressive statement piece of jewelry.
