A thin layer of solid opal that is fixed to a base of opaque material (a doublet), or a doublet with a fixed clear top (a triplet) We do not stock triplets.

A host rock is impregnated with natural opal which cannot be readily separated from the host rock. This classification includes doublets and triplets containing matrix opal but does not include any item of or containing treated opal.

Solid opal or matrix opal that has been treated chemically or by other means to enhance its appearance. This classification includes doublets and triplets containing treated opal.
What is Synthetic Opal show
Material that has the same chemical and physical structure and the same appearance as naturally occurring opal, but which has been manufactured. This classification includes doublets and triplets containing synthetic opal. As opal miners we are totally opposed to Synthetic/Plastic Opal. We are constantly dismayed at how many customers we speak to who have purchased this material without being told that it is NOT natural opal.
