Mexican Onyx Faceted Diamond Shape Cabochon - 18x10mm

Mexican onyx is cut into a faceted diamond shape, about 18 by 10 millimeters, that catches the light on every side. It is not drilled.

Set it in a bezel or prong setting, glue pairs onto ear posts, or add it to rings and pendants. Choose 1, 5 or 10; larger packs lower the price per stone, and a matched pair makes elegant drop earrings.

Mexican onyx is banded calcite, a softer stone than true onyx, so protect it from scratches and harsh cleaners. Each stone varies slightly in banding and shade. Because the facets are cut on a soft stone, settings with a protective rim, such as bezels or pendants, help it last longer than everyday rings.
