3 Nice Rough Coober Pedy Opals 78.4cts Multicolour Fires/Bars White/Crystal Base

I have for sale 3 nice Coober Pedy Rough Opals from Australia. These weigh 78.4cts in total. The 2 larger pieces are white base crystal/seam material. Nice Bars/Patterns and some sand/skin to look at. The other is a Crystal Seam, with bars 2/3rds through. All multicolour stones, will cut some cabs/freeforms, or keep as they are.  Thanks for looking.
