I have for sale a Nice Parcel of Rough/Rubbed Koroit Opals from Queensland Australia. These weigh 481cts in total. These are Ironstone material and have great patterns through some of them. 3 have Nice Fires, Greens in 2 and red Fine veins in another. The other 4 have Slight/No Fires in them, and are Great Practice pieces and specimens. Should get 3 usable cabs freeforms from these. Thanks for looking,.,.,.,.
