2 Larger Rough Boulder Opal Specimens 4698cts Queensland Australia Blue/Green Fires

I have for sale 2 pieces of Rough Boulder Opal from Queensland Australia. These weigh 4698cts in total. Ironstone base material, one much larger than the other. The biggest piece has a thick section of Green/Blue Crystal Opal in a bar through it, mixed with some ironstones. Superb large Specimen piece, or see what it cuts. Multiple pictures stones or similar.  The second has some White/Crystal Opal on one face. Slight Red/Green Fires in that.  Thanks for looking.
