All about Black Onyx

Onyx is formed from the mineral Chalcedony, which is banded in Quartz and Moganite in parallel lines to form Onyx. Chalcedony also makes up Agates, but they are swirled with bands of the minerals. 

It is very rare to find true Onyx, as many of the gemstones available are not true Onyx but are chemically enhanced agate. Agate is more plentiful and is typically chemically treated to form the desirable black Onyx color. Sardonyx is a red-toned onyx that is also popular. 

Black Onyx is the most popular type of Onyx, but there are Onyx gemstones that are available in white, black, blue, green, gray, yellow, and red. These gemstones often form the base of cameos and are known for their bandings of color, typically one color for the background, and the relief is the lighter color to stand out.

When Onyx is chemically treated, it is done through boiling in a sugar solution and then treating with hydrochloric acid. Jewelers can enhance the top layers of the stone to get a more desirable black color.

 These color enhancement techniques have been around since the first century. 

Nitric Acid is also used to lighten or change colors in the agate to get rid of undesired coloration. The most widely used artificial Onyx material is a banded Calcite which makes up the majority of carved Onyx items now. 


Onyx has a long history of being used for carvings and jewelry. Cabochons and beads are popular uses for Onyx, as well as carving into Cameos. 

As far back as the Second Dynasty in Egypt, bowls and small pottery items were carved out of Onyx. Worldwide, It was also popularly used as a base for sculptures and figurines. 

And due to its black coloration, Onyx was often found in Mourning Jewelry created in the Victorian Era. The Onyx stone is generally considered a stone of bad luck.

In China, Onyx was mined by slaves and servants. The stone was considered bad luck to own due to fears of misfortune and bad dreams. Although it was considered unfortunate in China, the merchants there were able to trade it to Westerners who were unaware of the negative attitude towards the stone. 

When choosing a Black Onyx, look for a shiny luster, striping within the stone of bands of white, and no surface imperfections.

Alternative Gems to Onyx

Obsidian fractures into extremely sharp-edged pieces when broken and has been used throughout time to make cutting tools. Obsidian is most often fashioned into beads and cabochons. It can also be polished into such a high shine that it has been used as a mirror. 
  • Black Tourmaline- This readily available crystal is found on every continent in the world. Its hardness makes it a great alternative to Onyx and for jewelry. Tourmaline in black coloration is not popular in fine jewelry but is extremely popular as a healing stone or crystal.

While Black Onyx is a beautiful, deeply colored stone, treated Onyx is far more beautiful and deep-toned than natural Onyx. While this gem is pretty, my recommendation would be to keep the purchase as a costume piece of jewelry and not go for an expensive Black Onyx ring. Black Onyx simply isn’t going to increase much in value in the future, and there are better quality stones available for investment pieces. Buy your Black Onyx, but wear it only occasionally and take care not to damage it or handle it roughly.
