ONYX: is a form of microcrystalline Quartz called Chalcedony. The name comes from the Greek word "onux" which means "fingernail" or "claw". Originally, almost all colors of chalcedony from white to dark brown and black were called Onyx. Today, when we think of Onyx we often preface the word with "black" to distinguish it from other varieties that come in white, reddish brown, brown and banded. Most of the Black Onyx that is commercially available today is color enhanced (heated and dyed) to increase it's depth of color.

Onyx is one of the birth stones listed for the zodiac sign of Leo. It is also the mystical birthstone for the month of December and the stone representing the tenth wedding anniversary. Onyx is said to separate and help release negative emotions such as sorrow and grief. It is worn to defend against negativity and Black Onyx is said to have protective energies in the sense that black is the absence of light, and therefore, can be used to create invisibility. It is also believed to fortify self confidence and responsibility, sharpen your senses and encourage a healthy self esteem.
