This large black opal is from the well-known Jag Hill opal fields. This piece should be carrying a price tag of $30k+
However, the opal cutter that cut and polished this piece more than 20 years ago did not remove the natural fracture in the back of the stone. There is also a natural  hallow in a section of the stone between the color bar and the potch

My Guarantee to you: If you are not more than satisfied with any of your purchases, please return the opal in its original condition. As soon as you return the opal we will process your refund 100%. We offer a money-back guarantee on all purchases without exception. We are seeking happy customers. Because I live and work mainly in Lightning Ridge where there is no access to Fed-Ex or major international shippers, Australia Post is the main shipping service I will be sending items through (unless the opal is being sent via my wife Helen or associate Jing from the Philippines) Australia Post is very reliable.
We are completely determined to earn your positive feedback and are happy to discuss any issues at any time as we seek only positive feedback.

We do offer combined shipping

Blackopalaustralia does not and will not enhance any of our opal photographs in an attempt to make the opal look better than the actual stones.
Thanks!
