I have for sale 2 Nice Rubbed Matrix Opal Specimens from Queensland Australia. These weigh 371cts in total. They are MIxed Dark Ironstones, pods, with some Fires in places, and Light Sandy/Clay type mtrix between them. Interesting material, messy to cut/clean up. These are Specimens/Practice parcel, may clean up usable pieces to, maybe use the pressure treatment on them to stabalise..  Thanks for looking.,,.,.
