Exceptional Black Pattern Opal--"Fireworks"
Lightning Ridge, New South Wales, Australia
This world-class gem is a memorable pattern opal reminiscent of a starburst or "fireworks". Its focal point is a red lozenge-shaped center from which extend red "rays" and a multitude of rich green, blues, orange hues. The play of color is present and luminous even in a darkened room and is not at all dependent upon the direction of the stone. This is a very fine gem suitable for the knowledgable collector and one of the most memorable pattern opals to be offered at auction in the last decade. Weighing approximately 20.45 carats and measuring 22.5 x 20.4 x 7.9mm
