Three constructions

All three are real opal

The difference lies in the construction, the price and the care. Which construction your piece has is stated on the product page and on the certificate.

Solid opal from the side: one continuous piece, no layers

Solid opal

All stone, a single piece of natural opal. For example Ethiopian Light.

All solid opals
Doublet from the side: opal layer on a dark base

Doublet

A thin layer of real opal on a dark backing. For example Circle of Colors.

All doublets
Triplet from the side: base, opal layer and quartz cap

Triplet

Plus a clear protective cap over the opal layer. For example Heart of Fire.

All triplets

The most common worry

Is a doublet fake? No.

The colorful layer is real, natural opal, only thinner than in a solid opal. The dark backing underneath makes the play-of-color glow more intensely.

A fake would be glass or plastic, such as opalite, or a lab-grown stone. We sell neither. What is inside your piece is stated on the product page and on the GSB certificate in the box.

Authenticity & GSB certificate

From the opal encyclopedia

Why doublets and triplets exist

Many opal finds are too thin to cut a solid stone from. Instead of discarding the play-of-color, the cutter gives it a stable foundation.

The dark backing absorbs the stray light behind the opal layer, so the colors glow visibly stronger. In a triplet a clear cap protects the color layer like a tiny watch glass.

The triplet suits a smaller budget, the doublet suits everyday wear. Anyone looking for a piece for life ends up with solid opal.
