You might have a natural opal, you could have a doublet, but you also might have a triplet! The difference between a doublet and a triplet is that a triplet has three layers instead of two (shocking!).
Where doublets have potch and the opal color bar, triplets have a third layer. This third layer is quartz that has been cut into a cabochon to magnify the thin color bar beneath it. You will be able to spot the glue in triplets the same as doublets.
We hope that you enjoy this weeks video!
