Product Descriptions

What is Black Opal and why it is Valuable?

Black opal is characterised by a dark body tone which can range from dark grey to jet black.

This vibrancy of colour makes black opal the most valuable form of all opals. Often a black opal will have a natural layer of potch (colourless opal) left on the back of the stone, which can give the stone an extra darkness and vibrancy of colour. The darker this potch backing is, the darker the body tone, which usually makes for greater vibrancy of colour and a higher value black opal. This is the principle upon which??doublets and triplets??are based, which are an imitation of solid black opals.

By comparison, black opals are the most valuable form of opal ?????????????????????????????????????????????€??due to their dark body tone and the resulting vibrant play of colour.
