Doublet Opals are a man made gem which uses a thin slice of real solid opal, and attaches it to a black stone or plastic backing to enhance the stones colour. If the stone is mounted so that the back and sides aren’t visible, it can be difficult to differentiate a doublet opal from a solid opal.
Doublet Opals can’t be valued by carat weight as the black stone or plastic is valueless. However based on the brightness, play of colour, pattern and size, we can come to a valuation.
Doublet opals are best matched with a silver or 9kt gold mounting. They are a great option for less expensive jewellery as the stones aren’t as expensive as solid opals.
