2 Nice Rough Boulder Opals Specimens 809cts Queensland Australia Some Fires Green/Blue

I have for sale 2 nice Boulder Opal Rough Specimens from Queensland Australia. These weigh 809cts in total. They are Ironstone base material with some areas/part faces of Opal on them. The largest has a triangle of better Fires/Bars Gold/Greens on one side, also some potch/crystal and only slight colour on the other faces. The second has some Blue/Greens on the top face, slight pattern/colour elsewhere. Great specimens, or cut a few Picture stones and similar from them. Thanks for looking.
