What's a Triplet?
Triplets are made from a thin layer of high grade opal cemented to normally a black or dark backing.
A clear dome cap of either glass or quartz is then cemented to the face of the opal.
The cap magnifies the intensity of the opal's colour and pattern.
The cap also protects the opal.
The high grade opal in triplets is greatly enhanced by the dark backing and capping.
Triplets are great value buying as the intense colours and patterns greatly resemble black opal but at a fraction of the cost.
