FIND YOUR PERFECT OPAL DOUBLET

An opal doublet is a 'composite' opal, made of a thin slice of opal on top and a dark backing. The dark back section, which can sometimes be made of ironstone, enhances the opal colours to replicate the look of a black opal, however without the sometimes expensive price tag. This eye-catching gem is a popular choice to set into a pendant, ring or earrings. They simply look stunning and are more affordable than Lightning Ridge black opal.
