I have for sale 3 nice rough/sliced Koroit Opals from Queensland Australia. These weigh 4126cts in total. Ironstone base material, each with pattern and some Fires. Largest is a sliced/half nut. Some patterns and Green Fires along one of the skins. Back is rough. Next a conglomerate piece, some Fires/PODs and similar through it. Last is part of a nut with some Blue/Purples. Good sizes, some pitting in a few places. Will slice up, specimens, cabs and similar. Thanks for looking.
