Product Overview

If this is your first opal, it helps to know what to expect. Opal is not a hard, sparkling stone like a diamond. Its charm is soft, moving color that changes as the stone or the light moves. A black opal gemstone shows that color against a dark background, and many first-time buyers find that easier to enjoy. This Ethiopian opal is a good place to start.

Product Frequently Asked Questions

Yes, more than other types of opal. A dark body is less common than a white or light one, and the dark background is what makes the colors stand out so well.

Real opal shows color that shifts as you turn it, and the pattern is uneven. Imitations often have a pattern that looks too neat and repeats, like fish scales. You can also ask the seller if the stone is a solid single piece.

There is no official master number for black opal. Master numbers like 11, 22 and 33 come from numerology, and they belong to dates and names, not to gemstones. If a stone feels right to you, that is a personal choice.

No. Onyx and spinel are plain black stones with no color flashes. Opal is the one that shows red, green, blue or gold as it moves.

This cut is called a cabochon. Opal is not cut with flat facets, because facets would break up the color flashes. A smooth dome lets the color spread across the surface.
