Black Onyx Crystal Bracelet Bead size:8 mm This Uruguayan geode offers aBlack onyx an even, depthless black with a glassy polish, the chalcedony the ancient world carved into seals and cameos. No flash; the appeal is the pure black and its cool weight. Onyx is microcrystalline quartz, the straight banded kin of agate.
