Superb Koroit Opal Rough Nut Parcel 483cts 3 Pieces Fires/Patterns Matching Set Qld Au

I have for sale a Superb Set of Matching Koroit Opals from Queensland Australia. These 3 pieces are all part of the same Nut, they weigh 483cts in total. They fit together, with only a small amount of the original nut missing. There is one larger piece with Solid Patterns/Fires through it, then the 2 other pieces. The main nut changes from a larger pattern with light clays in the pattern, to darker ironstones. All with Green/Blues mixed through.  Hard to get, and great quality set. These are a Collectors parcel, or maybe cut them and get a set of matching Cabs/Freeforms.,,.  Thanks for looking.
