Onyx Stone

Onyx is a semi-precious form of chalcedony, which has alternating straight bands of color, most commonly red, white, brown and black. Chalcedony is the group name for a large family of stones, all of which form from silicon dioxide, also known as quartz.  The color of onyx is created through impurities which seep into the rock as it forms.

Translucent onyx slabs can be back lit to accentuate the beauty of natural stone.
