This is a natural untreated rough specimen form the Quartz mine in Queensland that was mined over 20 years ago.This is opal that has formed in the biscut [sandstone] band.There will be some faults in the stone but the area is known for the amount of silica in the sandstone which will take a decent polish.This is not easy material to polish as a leather wheel is best to finish it and you may have to leave some pit holes in the stone but it will be a rewarding experience for you.
