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.
