This listing is an Australian opal solid. The material is a translucent gray base with flashes of red, blue, green and yellow, with yellow/green being the predominant color.
The stone weighs 5.5ct and is 15mm x 13mm and 4mm deep.
I recently produced the stone from a nice piece of rough that I purchased to fill a custom order. This freeform designer cut opal would work up into a beautiful pendant. This opal should be set in 14kt gold at the very least. A nice stone with strong color distributed evenly throughout. This opal is from the Cooper Pedy mine in Australia.
