WHAT IS A DOUBLET AND TRIPLET OPAL?
A thin slice of crystal or light opal is laminated onto a layer of dark material to form a Doublet. The addition of a clear dome of crystal, where the crystal opal is sandwiched between the clear dome and the layer of dark material, makes it a triplet. The clear dome capping gives the opal layer protection.
