I have for sale a Larger Parcel of 4 pieces of Rough Queensland Matrix/Fossil Opal from Australia. These weigh 1830.5cts in total. Ironstone base material with Patterns and some Fires in places. The smallest piece has a Fossil sat in the Top, with some Nice Green Fires in it. Great specimen. The others have mixed Patterns, some with Light Purples when moved, another with Thin Green/Blue patterns mixed through the material.  Specimens/Practice/Gamble material and should clean up some Great Specimens and maybe freeforms once worked though.  Or leave them as they are,.,.,. Thanks for looking.
