Bin-08
A large rough chunk of Mexican onyx in white, cream, yellow, tan and brown, sold by weight at 1 to 1.5, 1.5 to 2.5 or 2.5 to 3.5 kilograms.
Use it as raw stone decor on a shelf or bookcase, or as carving and lapidary material.
Natural holes and pits are part of the stone. Mexican onyx is a soft calcite that reacts with acids, so keep it away from acids and harsh cleaners. Each chunk varies in color and shape.
Despite the name, Mexican onyx is banded calcite, a softer stone than true onyx, which is a form of chalcedony.
