ABOUT DOUBLET OPALS
Australian doublet opals consist of two layers - a slice of exceptional quality, colourful natural opal set onto a black backing made of resin, ironstone or potch, which darkens the appearance of the gemstone. Doublet opals are suitable for all types of opal jewellery, including gold and silver settings, and are affordable alternatives to solid black opals. Read more about Australian opals.
