BOULDER ROUGH “QUARTZ’

This is a natural untreated rough specimen from the Quartz mine in Queensland that was mined over 30 years ago.This is opal that has formed in the biscut [sandstone] band.There will be some faults in the stone due to its age but the area is known for the amount of silica in the sandstone which will take a decent polish.you may have to leave some pit holes in the stone but it will be a rewarding experience for you.

I dont believe any more mining has been done in this area so it will make a interesting stone.
