Onyx is a mineral, like marble, granite or quartzite. It is part of the quartz mineral group and is a layered stone. Some of its layers may contrast.
You may see an onyx in black and white parallel layers or in brown and white layers called sardonyx.
Another type of onyx is the carnelian onyx that is composed of red and white layers.
Other Onyx Characteristics
Onyx has a Mohs scale hardness reading of 6.5 to 7, and it possesses a smooth, wax-like luster.
Onyx is often used as the background of a cameo broach, pendant or ring.
Most onyx is dyed to make its color uniform. It is also heat treated to bring out its color intensity. These two enhancements do not lower its value.
All onyx jewelry is relatively inexpensive. The metal it is set in will cost more than the actual onyx stone itself.
