Types of Composite Opal

Doublets or triplets are man made to allow miners to use gem quality stones that are too thin to be sold as gems.

Doublets are a composition of two pieces which are cemented together. Usually a thin piece of opal and a base of potch or colourless opal are used to form designs of unique and lasting beauty.

Triplets are a composition of three pieces. A thin layer of natural opal is cemented between a dark base material and a transparent protective top layer.
