SEDA ROUGH OPALS

This is a parcel of natural untreated rough of boulder opals mined in Queensland. The colour bar has been exposed and it is now ready for cutting & polishing. Most boulder opal has a thin precious colour bar sitting on top of ironstone so you have to be careful not to rub too deep. Having ironstone exposed in the face of the stone is acceptable for commercial stones.
