Nice Rough Sliced/Split Boulder Opals 578cts Green/Gold Stripes/Fires Some Reds

I have for sale a nice parcel of 2 Sliced, Split, Rough Boulder Opals from Queensland Australia. These weigh 578cts in total. First has a nicepatch/bar of opal going all the way across, Green/Blue and some Orange Fires, with sand along one side. Very nice piece. Good thick Opal. The second has some Bars running through the caramel, thinner and more pastel, then a bright bar at the edge/side.  That should join through. Great Specimens or cut some Cabs/Freeforms, Nice parcel. Thanks for looking.
