    BLACK OPAL - 47.1 CT
    Mintabie Opal Field, Mintabie, South Australia, Australia
    Australia is the foremost producer of Black Opals in the world and the Mintabie region of South Australia is one of the world's most remote regions producing these rare Opals. The Aborigines were the first to sell Black Opals from the Mintabie area in the late 1910's but the remote locality, harsh conditions, and hardness of the host sandstone precluded any serious production until 1976 when large machinery was finally introduced into the area. Finally, the full potential of the Mintabie Opal fields could be realized. This bright Black Opal oval cabochon is from the Mintabie area - it has a low dome with predominantly green pinfire flashes with occasional flashes of blue-purple, yellow and orange. The fire shows equally well from all directions and the body is classified as a N3/N4 Black Opal. There are minimal inclusions of host rock on the backside but they are not visible from the front. This fine, large gemstone has very good polish, weighs a sizable 47.1 carats, and measures 45.47 mm x 22.03 mm.
