I have for sale a parcel of 5 Cut/Polished Koroit Opals/Freeforms from Queensland Australia. These weigh 264cts in total. Ironstone base material with patterns through them. Some double sided stones here, a Nut with banding and good colours.  Also a Blue crystal pattern that looks like small dolphins jumping. Each has some Fires/Patterns to look at, Great for making pendants/jewelery.  Thanks for looking.
