Our sellers have permission to offer images of rough opal wet to help expose the colour to buyers.

Boulder opal is still reasonable price from boulder opal fields which includes matrix rough but cutters need slightly bigger cutting equipment and especially larger saw blades to work this material. Opal fields from Andamooka to Mintabie and Koroit to Yowah are now only small mining operations.

Black opal rough form Lightning ridge NSW is in high demand and opal miners now work this material to check if any top expensive gemstones are in it.

Ethiopian rough opal has now filled the vied and many opal cutters have only worked this type rough opal due to regular supplies and inexpensive compared to Australian rough opal.

Yowah opal rough is also popular with new cutters who appreciate the pattern in these opals. International opal fields include Mexican opal, Honduran and Brazil opal rough but supplies are not constant and quality varies greatly.
