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" derives from the Greek word "onux", which means "nail". The name of the stone would be linked to a Greek legend. According to this legend, Eros cut Aphrodite's fingernails while she slept and the gods turned the clippings into stone.

Onyx usually has a black base and a white top, but specimens of other colors can also be found, such as brown and red. Among the most common varieties of this gemstone are sardony onyx, which has a white top layer and brown base, and carnelian onyx, which has a red base and white top layer.

While black onyx is the most famous variety, sard onyx and cornelian onyx are actually more common. In this article, we explore this gemstone in more detail.


How to identify 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. In general, 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 as a single color. In this case, the gem is more difficult to identify and can be confused with other similar stones.

As mentioned earlier, onyx is a form of agate, which means the stone is related to all other varieties of quartz. When the stone is 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 similar-looking stones. 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; usually these are black and white, with bands of alternating colors. Occasionally specimens may be brown or red, rather than black. For example, a variant of onyx called Sardonyx has brown bands instead of black.

While black onyx is the best 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 coloration of specimens. Various dyes are used to enhance the black color of black onyx and the brown color of sardonyx. It is surprising to find that most of the black onyx sold today on the market are artificially colored.

The name black onyx is sometimes incorrectly used to refer to similar-looking materials. For example, Banded Calcite is often mistakenly called Black Onyx. As calcite is readily available, the material is much cheaper; therefore, stores can cut, polish, and sell the stone for less than real onyx.
