Black Onyx Gemstones - Beautiful Black Onyx – It’s Magical
Black onyx is part of the beautiful chalcedony family of gemstones which includes agate, cornelian, and chrysoprase. Black onyx as a gemstone became popular in ancient Greek and Roman times. It was and is used not only in jewelry but for decorative items around the house. Some black onyx forms in parallel layers of black and white which makes it very suitable for cameo or intaglio carving either for jewelry or plaques or cups or many other items.
Black Onyx Stones Look Great in Jewelry
