Loose Black Opal Stones

Solid, not doublet, not triplet

A doublet is a thin slice of opal glued to a dark backing. A triplet adds a clear cap on top. Both can look bright in a listing photo. The glue line is vulnerable to water and heat. The thin opal layer can’t be reshaped if your jeweler wants to adjust the cut . A solid is opal all the way through. Set it with confidence and it will outlast the setting.

Everything here is untreated. Nothing smoked. Nothing dyed. Nothing filled with resin. What you see is what the ground gave up.

How we choose what makes it onto this page

We don’t grade by chart. Licensed gem labs don’t, neither do we. Yuka has been at this since 2012, working alongside Lightning Ridge cutters and miners, and the eye for what’s worth selling comes from handling thousands of stones, not from a numbered code. What we’re looking for is fire that stays bright when you turn the stone in normal light. Color that holds across the face instead of dying in patches. A pattern that’s actually doing something. A stone with one bright flash and dead ground around it doesn’t make the cut. A stone with electric color from every angle does, regardless of how big or small it is.

Picking an opal for a ring or a pendant

Oval and teardrop shapes drop into standard ring mounts without fuss. For a pendant you’ve got more freedom. Freeform shapes and larger stones come into their own once they’re not fighting for finger space, and a flatter back is fine because nothing’s going to land on it. If you want matched stones for earrings, buy them as a pair. Two singles bought separately won’t match. Pair color comes from the same piece of rough or it doesn’t come at all.

Every listing shows real dimensions and weight. Message us to talk through whether a particular stone suits a particular design.

For trade and bulk buyers
