Nice Rough/Rubbed Mintabie Crystal Opal Parcel 20.3cts Multicolour Bars/Fires Australia (N)

I have for a nice parcel of Rough/Rubbed Crystal Opals from Mintabie. These weigh 20.3cts in total. There is 3 main pieces and a small 0.4ct chip. There is Multicolour bars running through the 3 main pieces, Reds/Golds/Greens/Blues. These will cut 3 cabs/freeforms there is some colour facing through. Nice colour at that. Some skin on the backs.  Slight gamble as the colour needs fully exposing, but once cut. They will make nice pendants, maybe rings and similar once cut/polished. Mintabie Opal getting rarer as the fields are closed to mining. (for now) Thanks for looking.
