Doublet Opal
Doublet Opals consist of a layer or slice of natural opal which has been bonded to a dark or black backing. The backing can be potch, black glass or ironstone boulder.
|
|
These days most doublets are bonded to an ironstone backing thus forming a "boulder doublet".
The dark backing enhances the colours and has the effect of simulating high quality black opal. However because less opal material is required doublets are much cheaper.
