2 Nice Rubbed/Preform Koroit Opals 215.3cts Patterns/Fires Queensland Australia

I have for sale a Nice Pair of Rubbed/Sliced, Preform Koroit Opals from Queensland Australia. These weigh 215.3cts in total. ironstone base material with Nice Patterns and some Fires mixed in to them. Blue/Greens mostly. These will take some shaping/final rubbing and ;olishing to make useful freeforms/cabs, or slice up for some smaller ones. Interesting material to work with. Thanks for looking.
