The name Onyx is derived from the Greek word Nux, which means “nail” or “sharp claw of animals”. The reason for this name is that the onyx stone can have veins on it that are similar to the color of human skin and flesh.
Of course, there is also a legend in the naming of this stone, which states that in the afternoon of a sunny day, Venus, the celestial goddess of love and beauty, was napping. At this time, her young child named Cupid (who is depicted as a winged boy with arrows and arrows in the books) cuts Venus’s nails with one of the sharp magic arrows. The pieces of cut nails fell into the water of holy rivers and since they were heavenly and celestial, they went to the bottom of the water and turned into Enyx.
What is the stone of onyx?
Onyx is a type of chalcedony mineral with black and white parallel stripes, which can be seen in different colors, but in the market, its uniform black type is more popular and sells more. Onyx stone is formed from silica deposits in the pores of volcanic lava.
The difference between onyx and black opal
Contrary to popular belief, onyx is not the same as black agate. In fact, black opal and onyx are both layered types of chalcedony, which differ in the type of bands and bands on the stone.Agate has circular bands facing the center like a ring while onyx has parallel and straight bands. Onyx strips are usually black or white, but can be a combination of colors with shades of blue to purple. Often, these bands start from the bright side and separate in the dark part.

In opal, the layers between the bands can have different colors. Also, there is a little transparency in agate and the stone can have different colors. But in onyx, the colors are generally matte and uniform (in the range of one or two colors).
Onyx stone processing:
In most cases, onyx is dyed to make its color more clear. These methods have been used for hundreds of years.
Immerse the stone in a chemical solution of melted sugar (carbon solution) and heat it with sulfuric acid to absorb the black solution to its upper layers and turn it into a uniform black onyx.
Other methods are also done with synthetic dyes along with nitric acid (removing annoying colors), which are generally sold in the market under the name of “black onyx”. Original and natural onyx stones can have white or black stripes, which, of course, are easier to recognize in rough samples. In ready-made gems, it is difficult to recognize whether the agate has been painted black or if it is really Enix.
