I have eleven stones weighing between .165 oz. This opal is most unusual, I have only ever seen it from two different miners. There is just about every colour of the rainbow in each stone, they are all very high yielding. There is one magnificent piece that weighs 1.1 oz. I will be happy to send one of these stones to you on the understanding that if it doesn't meet your full satisfaction I will allow you a full cash refund.
Mintubi opal is really gem material.
You will have a lot of fun cutting it and you will end up with a stone that is worthy of becoming a family heirloom. It really doesn't matter what type of opal you use, I think everyone aspires to having something of the best. About AOM Copyright 1999, Australian Opal Mines. All rights reserved.
