This is a natural untreated rough pipe 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 .You can cut it as a specimen or it can be cut up for inlay or doublets

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