Onyx Jewelry

It is. Onyx is a natural variety of chalcedony, a form of quartz, carved and set since antiquity. That deep, even black is traditionally achieved with treatment, a stable, permanent practice as old as the stone's place in jewelry, and the industry standard for black onyx everywhere. What matters on the hand is the same: real stone, true black, and a polish that holds for years, which is exactly what we choose it for.

Yellow gold. We set our black onyx in 14K and 18K yellow gold because warm metal makes that deep black read intentional and rich. Black onyx and gold is one of the oldest pairings in fine jewelry for a reason.

Both, depending on the piece. A slim onyx deco ring goes with everything and wears daily. A geometric statement earring or an onyx and diamond tennis necklace is built to be the loudest thing in the room.

Beautifully. We pair black onyx with diamonds for contrast, and in a few pieces we set emerald or ruby against the black for a jolt of color. Onyx is the backdrop that makes everything beside it look sharper.

Simply. Onyx sits at 6.5 to 7 on the Mohs hardness scale, durable for regular wear, though softer than sapphire or diamond, so store it where it avoids contact with harder stones. Warm water, mild soap, and a soft cloth keep it clean; keep it away from harsh chemicals and perfume, and it holds its color and polish for years.
