Australian Boulder Opal Rough
From The Queensland Opal Mining Fields of Koroit, Quilpie & Yowah ...

Very Rare Koroit Gem Matrix Boulder Opal Picture Rub

Our Boulder Opal Rough is individually sliced and faced.

Each boulder opal piece has been trimmed with both sides cleaned up and given a nice shine to their surfaces, so that their cutting potential is more clearly visible.

This material is still classed as "rough boulder" and still needs orientating, cutting & polishing to produce your quality finished Boulder Opal piece!
