Triplet opals are very popular as they display brilliant colours and patterns at only a fraction of what a solid gem opal would cost.
Triplet pairs are ideal tyo make matching earrings or matching ring and pendant sets
A triplet opal is composed of a thin slice of crystal opal sandwiched between a quartz or glass top and a backing made of black potch or manmade resin.
The black backing greatly enhances the opal\‘s fire colour and the quartz or glass top protects it. Triplet rings can last over 20 years, just needing an occasional polish (which a local jeweller can do). Getting these rings wet is not recommended.
