L'onyx is a stone that appears in various cultures and is considered one of the most popular gemstones in the world.
The name "Onyx" is said to derive from the Greek word "onux", which means "nail". The name of the stone is linked to a Greek legend. According to this legend, Eros cut Aphrodite's nails while she slept and the gods turned the clippings into stone.
Onyx generally has a black base and a white upper part, but specimens of other colors can also be found, such as brown and red. Among the most common varieties of this gemstone are sardonyx onyx, which has a white top layer and a brown base, and carnelian onyx, which has a red base and a white top layer.
While black onyx is the most famous variety, Sardinian onyx and Cornelian onyx are actually more common. In this article, we explore this gemstone in more detail.
How to Identify Black Onyx ?
Even to the untrained eye, onyx can be identified quite easily. With its characteristic black and white bands, this stone is rarely confused with other gemstones. Typically, onyx gemstones have a black base and a white top layer, but coloring can vary depending on the type of onyx. For example, Sardinian onyx has a brown base, and carnelian onyx has a red base. Some specimens may appear only one color. In this case, the gem is more difficult to identify and may be confused with other similar stones.
As previously mentioned, onyx is a form of agate, meaning the stone is related to all other varieties of quartz. When the stone is only one color, it can become difficult to distinguish from black jade, tourmaline and black diamond. For trained professionals, however, identification is simple, as onyx is much softer and less lustrous than other stones of similar appearance. The gemstone can also be confused with jet; however, jet is much softer than onyx which measures 7 on the Mohs scale.

The different colors and types of onyx
Onyx is constructed from strips of chalcedony; typically these are black and white, with bands of alternating colors. Sometimes specimens may be brown or red, rather than black. For example, a variation of onyx called Sardonyx has brown bands instead of black.
While black onyx is the most well-known variety, it is actually less common than red or brown banded onyx. As with most gemstones, onyx often undergoes artificial treatments to enhance the coloring of specimens. Various dyes are used to enhance the black color of black onyx and the brown color of sardonyx. Surprisingly, most black onyx sold in the market today is artificially colored.
The name black onyx is sometimes used incorrectly to refer to similar-looking materials. For example, Banded Calcite is often falsely called Black Onyx. As calcite is readily available, the material is much cheaper; therefore, stores can cut, polish, and sell the stone at a lower price than real onyx.

Unlike many gemstones, onyx deposits are found in various locations around the world. Notable sources include Argentina, Australia, Brazil, India, Botswana, Madagascar, Mexico, Myanmar, Pakistan, Sri Lanka, Uruguay and the United States.
