42 Cts Natural Australian Opal Shell Parcel, In The Rough, Coober Pedy. These 3 shells have a full spectrum of colours. Big shell has the least amount on white base. You can see red hiding in there. I don't think it will make a high quality gem. The smaller one is beautiful with reds, greens and blues mixture between white and crystal. The money maker is the middle piece and it will pay for this parcel. Full spectrum of beautiful crystal and it is very big piece of opal that has been cleaned and the risk was taken out of it.
