Black Onyx

Black Onyx is a striking variety of chalcedony quartz, renowned for its smooth, deep black appearance often enhanced by fine white banding. Formed through the deposition of silica in volcanic lava cavities, Black Onyx boasts a dense, uniform texture and a waxy to vitreous luster.

With a Mohs hardness of 6.5 to 7, Black Onyx is durable and ideal for a wide range of jewelry applications, from elegant beads to polished cabochons. Significant sources include Brazil, India, and Madagascar.

Celebrated for its protective and grounding properties, Black Onyx has long been cherished as a stone of strength, resilience, and focus, making it a timeless choice for both fashion and spiritual purposes.
