Opal Doublet - Silver Pendant

925 Silver pendant with a Opal Doublette from Coober Pedy, Australia.

What is a doublet?
A thin slice of opal, combined with another stone. This is done with opals that are too thin to be worked with normally and also to reduce costs.
A solid opal is often up to ten times more expansive then a similiar beautiful opal doublet.
