I have for sale a Nice Parcel of Rough and sliced Opalton Matrix Opals from Queensland Australia.  These Ironstone base pieces weigh 787cts in total.  These are Sliced and Rough pieces, all with some Colour/Fires/Veins shoing somewhere in them. Lots of Puprles/Greens in these. Great Specimens, Parctice material, and interesting specimens. Should be some usable stones once worked through and cleaned up aswell.. Lots to look at in this lot,. Thanks for looking,.,.
