A doublet from Opal House is a slice of precious light crystal opal that has been enhanced by bonding ironstone to the back. This gives the opal a black or boulder opal look. Doublets are made to enable people to enjoy the beauty of the precious opal at a more affordable price.


A doublet becomes a triplet when a clear quartz crystal is superimposed on an even thinner slice of opal. The protective crystal dome also helps to enhance the precious opal by magnifying its true colours. Triplets traditionally use a lower grade of opal than doublets, for this reason we do not use triplets in our jewellery.
