This polished freeform gem opal, is from Mintabie, in south Australia. It was mined long ago, in the "Old Field". It carries beautiful and valuable Red, with blue and green also, from all angles. A stunning broadflash pattern exists across the face. It has brightness of 5/5 and will suit a collector, or high end jewellery designer. Mintabie has now been closed, by the Australian government so represents a good investment. It weighs 8.4 carats and measures 21.5 x 14.8 x 5.4mm. It carries a pinfire gold pattern o the back of the stone. This is large enough to be recut, to suit specific dimensions for existing pieces, but I feel should be left whole, given its immense value.
