This is a interesting piece of natural rough from the Koriot field that has been tumbled and is now ready for polishing. I bought this rough from an old part time miner who likes to rub his material down and then to tumble it so its smooth and ready for polishing.This material has the precious opal embedded in the iron/sandstone matrix and is showing some  nice colour.

This material takes a great polish and is easy to get a high gloss on.

The photo is taken with the stone wet.

Natural untreated

Weight 26.94 cts app


Size  24 x 18 x 6 mm app


Note we use a Nikon camera that captures the mauve in blue stones which the eye cant see so consider this colour to be blue.
