Queensland Boulder Opal Rough/sliced Parcel 1593cts some Patterns/Fires :)

I have for sale a Larger parcel of Rough/Sliced Boulder Opals from Queensland Australia, these weigh 1593cts in total. They are Ironstone base material, some with Pattern, and some Opal/Potch mixed in. Slight Fires mixed into these. Lower Grade/Practice material overall, good sizes to work with, should be some nice Freeforms/Pictures stones too once cleaned up,.,. Thanks for looking.,,.
