In this video Justin takes us back to basics and clearly explains the difference between black opal and crystal opal. He explains with the help of a torch.
First up he shows a dark crystal opal and shines a torch at the underside. The light travels straight through it – clearly indicating that it is a crystal opal because it is translucent. He also does the same with a true crystal opal.
Next up is a black opal. The black of course referring to the underside of the opal where there is no colour. This potch is also opal – it just doesn’t have colour exhibited. In this case, when you shine a torch the light doesn’t travel through the opal at all – indicating a dark, semi black or black opal.
Watch the video and you will get a clear understanding of the differences.
