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 make 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
The black onyx carried by is uni-colored black chalcedony. It has a hardness of 7 on the Mohs scale and it is perfect as a background for setting with gemstones of color especially those that are bright in color like yellow or pink sapphire, emeralds or tsavorite, rubies or diamonds. It is also beautiful set in yellow or white gold or silver all by itself. For many years, it was very popular and became a classic for gents rings and it is beautiful set with marcasite or used in Victorian style jewelry.
