Not actually sold but returned to AMO
Deep blue, striated and prismatic Azurite crystals with chisel terminations. The largest crystal is 2.3cm. The backside has two crystals broken off but does not show from the front side of the specimen as seen in the first photo. Ex. FJ Barlow collection. Excellent and attractive specimen.
