Black Onyx

The Quiet Strength

Black Onyx has long been valued for its deep, uninterrupted black surface and refined simplicity. Its rich tone gives the stone a quiet strength that has made it a timeless material in jewelry for centuries.


The Stone

Black Onyx is a variety of chalcedony, a form of microcrystalline quartz. The gemstone is known for its smooth, uniform color and its ability to take a high polish, giving it a clean and elegant appearance.

Because of its simplicity and depth of color, black onyx has become one of the most enduring materials used in jewelry design.


A Stone With History

Dark stones have appeared in jewelry throughout history, from Roman signet rings to Victorian mourning jewelry. Onyx in particular became widely used during the nineteenth century for cameos and decorative carvings.

Its understated character has allowed the stone to remain relevant across centuries of design.


Black Onyx in Jewelry

The deep black surface of onyx provides a strong visual anchor on the wrist. When paired with precious metals like sterling silver or solid gold, the contrast creates a refined and balanced appearance.

Because of its versatility, a black onyx bracelet can be worn on its own or alongside a watch without feeling excessive.


The Bracelet

The Posh Stone Black Onyx Bracelet is crafted from carefully selected 6mm natural gemstones and finished with a solid sterling silver clasp or an optional solid 14k gold clasp.

Each bracelet is assembled by hand in California and designed to be worn daily as a modern heirloom piece.
