About Black Opal

Black Opal is a gorgeous stone that displays beautiful multicolored effects. It is widely available as treated black opal which undergoes a smoke treatment to bring out its color. This opal is often produced or mined in Ethiopia.

The smoking process deepens the color of the Opal and enhances the play of color. It is made to appear closer to Lightning Ridges Opal through this process. The Ethiopian Black Opal is a great value gemstone with a masculine appearance and therefore an affordable alternative to Untreated Black Opal.

What Colors can Black Opal Display?

The exciting part of this question is the answer to it which is all colors; however, we do tend to see some uniformity to the stones as they tend to lean more to green, red, purple, or yellow, etc. Some Black Opals are almost entirely black with only a flare of colors while others can appear with the base hues we’ve mentioned above. Some of the stones appear speckled or even marbled. The unique properties are what give character and qualities to each sample, and we believe you will have no trouble finding a stone to your taste with our enormous selection!

What is 'Lightning Ridge Black Opal?'

Natural and Untreated Black Opal is one of the most valuable Opals that exists. It is an incredibly rare, and incredibly expensive for that reason. The Black Opal found in Australia’s Lightning Ridge displays remarkable effects through simple cutting and polishing of the raw stones. These stones have given Black Opal its claim to fame. We don’t have ‘Untreated Black Opal’ often due to its rarity but feel free to check our inventory of Black Opal often if you should so choose.

Is Black Opal a Suitable Birthstone or Anniversary Stone Gift?

Yes, of course! Black Opal is the Gemstone to purchase your loved ones who were born in October. It is an affordable and masculine stone which can appear in numerous jewelry applications due to its availability. If you are looking to purchase Black Opal for an Anniversary Gift ‘be sure’ it’s the 14th as Opal is the accepted gift for this particular year.

Purchasing Black Opal for either of these occasions and having a custom piece made is an excellent idea.

What Kinds of Jewelry are suitable for Black Opal?
