- Doublet and Triplet - A doublet and a triplet are both composite imitation stones, consisting of two or three joined layers. A triplet is made with the crown and base of genuine material, but with a centre layer, usually of glass, the object being to make the stone appear larger than it really is. A doublet consists of only two layers.
Opal doublets are quite common and consist of a thin layer of opal cemented to an opal matrix or black glass.
