Black Onyx

Black onyx is a classic, versatile gemstone prized for its deep, uniform black color and glass-like polish. It's one of the most requested stones in jewelry making because it pairs with almost anything, from gold and silver to colorful gemstones and other neutrals, without competing for attention.

We stock black onyx beads in smooth round, faceted round, faceted cube, faceted rondelle, and star-cut shapes, sold by the strand. It's a durable, everyday-wear stone that holds up well in bracelets and necklaces alike.

Black onyx is typically dyed to achieve its rich, consistent black tone, a common and accepted practice since onyx naturally occurs in banded gray and brown. Each strand is quality-checked for consistent color and bead size before it ships.
