This is so-called “Flame Queen” Opal, discovered in 1914, by 3 men in New Sales Wales, Australia. Found at 35 feet underground, it is the best-known example of "eye-of-opal", an eye-like effect created when opal fills in a cavity. Its central raised dome flashes red or gold depending on the angle of view, and is surrounded by a band of deep blue-green, giving the stone an appearance somewhat like that of a fried egg. Black is the rarest, most valuable opal color for both its scarcity and the way the dark background allows for a brighter play-of-color when the opal is precious rather than common. Red color flashes, another term for play-of-color, are especially prized. The Flame Queen weighs 263.18 carats and is somewhat triangular in shape, measuring 2.75 x 2.50 x .50 inches. Our 1-inch thick, polished blocks are crafted using a unique casting method that ensures crystal-clear, deep, and realistic images. They stand upright on any flat surface, making a strong decorative statement. The Giclee process is used to create the print, enlarged for an unforgettable viewing experience. This piece makes a great holiday gift!
