This is a natural opal rough that have rubbed to expose the colour . shaped stone called . This material was a living tree 100 million years ago and the wood void has been replaced by opal. With fossil replacement its best to leave inclusions in as they can be hard to rub out. They make a great fossil specimen and can be cut or sculptured as they are.

This photo was taken with the stones wet.

-all weights and sizes are approximate.

All our stock has a money back guarantee provided its not cut/rubbed and we suggest you look at it with a loop dry before cutting

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
