A loose black opal refers to a gemstone that is not set in any jewelry. These include natural black opals, high-quality black opals, and even uncut black opals, offering versatility for customization and design.
What makes Australian black opals unique?
Australian black opals are renowned for their vivid play-of-color and dark body tone, making them the most valuable type of opal. Mined in areas like Lightning Ridge, these Australian black opals are often considered the pinnacle of black opal gems.
How do Ethiopian black opals differ from Australian black opals?
Ethiopian black opals are known for their unique patterns and vibrant colors. While Australian black opals have a more traditional dark body tone, Ethiopian black opals can feature translucent and fiery patterns.
What are semi-black opals and solid black opals?
Semi-black opals, also called gray or dark opals, have a medium-dark body tone, whereas solid black opals have a pure dark background that enhances their play-of-color. Both types are popular among collectors of black opal gems.
Are raw black opals and uncut black opals the same?
Yes, raw black opals and uncut black opals refer to opals in their natural, unpolished state. These loose black opals are ideal for those who want to shape or customize the stone themselves.
How do I care for my loose black opals?
To maintain the brilliance of your black opals, including solid black opals and semi-black opals, avoid exposing them to sudden temperature changes or harsh chemicals. Store them in a safe, moisture-controlled environment.
Why are black opals so valuable?
Black opals, especially high-quality black opals from Australia, are rare and known for their stunning play-of-color. Natural black opals and solid black opals with vivid color patterns are particularly prized among collectors and jewelers.

I did not realize these stones were of jewelry quality. They are really beautiful, just not what I was expecting which was more of a natural stone.

First time using this website. It was both exciting finding things in my price range and things Iam gonna save up for and use in other pieces. I love that the picture of the gem is the exact gem I'll be buying. I haven't tested the gems yes but they said they sold me 100% natural gems.

I have been buying gems for several years off and on and love their selection and great low prices. I started out wanting to get an example of each type of gem but after looking at all the types of gems and reading about them I realize it is almost impossible for me to do. It took me years just to read about them all. Gem Select is the best gem site you can find. For information or to buy. Steve M.
