About Doublets

A doublet is a type of opal composed in two sections.

It is sometimes used to imitate other, higer-quality opals. An opal doublet uses a thin slice of opal for the top portion of the stone. Natural opal is fused to a black stone backing.

The color of the opal used in the doublet is all that is seen. In reflected light, a separation line may be seen. A backing layer of onyx or matrix (ironstone) supports the opal layer and can make it look darker and of higher quality

Source your single-gem or parcel doublet opals direct from opal miners and opal wholesaler/dealers. Black doublet opals are made in Lightning Ridge, Australia using opal crystal and set on natural black opal potch. Most doublets are set on natural ironstone from Queensland Opal Fields

Most Opal doublets are made from Coober Pedy fire opals in South Australia and only few doublets are made from lightning ridge crystal opals.

Opalised shells actually make the best doublets as the opal skin is cabochon and very bright in colour so they make brilliant gem doublet opals.

Mexican opals are also made into doublets with good multi fire patterns.

The latest opals to be made into doublets are Ethiopian fire opals from wello.

This opals is hydrophane as it changes colour from white base to crystal when immersed in water,so special glue process is required to make Ethiopian fire opal doublets
