Onyx, a banded variety of the quartz family, is mined in Brazil, India, Madagascar, U.S.A and Uruguay. The only difference between onyx and other banded agates is that the stripes of onyx are even and uniform. Black onyx's uniform black color is achieved by dyeing and or by heat treating. The name Onyx is a Greek word meaning claw or fingernail, as it was once believed that onyx was created from the goddess Venus's fingernail clippings. Onyx and Sardonyx are essentially the same stone: onyx will have a black base, and sardonyx has a brown base. Also, be sure to check out our lovely selection of Onyx pendants!

Description: Onyx and Sardonyx are both a banded variety of chalcedony agate. They differ from other banded agates only in the uniformity of their stripes. Much of the black onyx on the market is dyed or heat treated to achieve a solid black color, making it nearly impossible to differentiate between black onyx and other solid black agates. Sardonyx typically has a red or a brown base with uniform banding. The name onyx stems from a Greek word meaning â€_Äúclawâ€_ÄÃ_ or â€_Äúfingernailâ€_ÄÃ_, as it was once fabled that onyx was created from the goddess Venusâ€_Äôs fingernail clippings.
