What is Onyx?

Onyx is a natural stone used for a wide variety of different purposes.  As well as for gemstones it's used for fireplace surrounds, household furniture and ornaments.

A great deal of confusion exists regarding the correct use of the name onyx.  In the vast majority of cases it's used incorrectly. 

With regards to colour, onyx is a black and white banded variety of the mineral agate.  It may also be a single coloured agate with alternating light and dark coloured bands (often black and white).

Although onyx and agate are both varieties of chalcedony which is a microcrystalline variety of quartz, the main difference is the bands in onyx are parallel whereas in agate they're curved.

Microcrystalline describes crystals so small they can't be seen with the naked eye.

What is Black Onyx?

Most black onyx is either black agate or black chalcedony.  Natural black onyx is pretty rare.

Throughout history the vast majority of black onyx has been dyed.  In one respected gemstone reference it's stated in order to achieve the colour black, stones are soaked in sugar or honey before being treated with sulphuric acid.

In his encyclopedia Naturalis Historia [circa 77-79 AD] the Ancient Roman author and naturalist Pliny the Elder speaks at length about techniques used to change the colour of one gemstone to make it look like another.

"There is considerable difficulty in distinguishing genuine stones from false; the more so, as there has been discovered a method of transforming genuine stones of one kind into false stones of another.

Sardonyx, for example, is imitated by cementing together three other precious stones, in such a way that no skill can detect the fraud; a black stone being used for the purpose, a white stone, and one of a vermilion colour, each of them, in its own way, a stone of high repute.

Nay, even more than this, there are books in existence, the authors of which I forbear to name, which give instructions how to stain crystal in such a way as to imitate smaragdus and other transparent stones, how to make sardonyx of sarda, and other gems in a similar manner.

Indeed, there is no kind of fraud practised, by which larger profits are made."


Ref; (Pliny's Naturalis Historia chapter 75).  

The history of the mineral onyx can be traced back much further than ancient Rome.  Onyx is said to have been one of the gemstones in the high priest breastplate.  This biblical garment was worn by Aaron the first Jewish high priest over the top of a tunic-like garment.

Onyx is said to have been the second stone in the fourth row.  To its left was a beryl and to its right a jasper.

Much of the banded onyx used for decorative purposes so items like chess sets, figurines and even tumbled stones are often banded calcite.  The reason for using calcite instead of onyx is because it's more readily available.  Furthermore calcite is much softer which makes it easier to work with.

On Mohs scale of mineral hardness onyx grades 6.5 to 7 whereas calcite grades 3. 

According to the traditional birthstone chart ruby is the birthstone for July.  Onyx can be used an alternative.
