Brazilian Opal Rough ,unlike Mexican opal rough there has never been lot opal rough available as most is cut in the opal fields or by opal miners themselves
Most are found in sandstone in quarry’s and are hand dug operations with pick and shovel.
Unlike Australian opal rough it is found in sandstone and siltstones as was washed down over the centuries by rivers
So this alluvial type opal is harder to mine in large scale operations
Brazilian opal is considered very stable and has white opal to fiery opal colours
When opal arrives and you are not 100% happy you can return for refund.
But if you alter or cut the rough it is yours and we cannot exchange
However, if you touch any piece, you are excepting ownership and negative feedback cannot be left.
But comments can be made as neutral if the rough opal didn’t cut to your expectations.
