KOROIT BOULDER OPAL CABOCHON (AUSTRALIA) – 10+ ct.
The Koroit area of Australia’s Queensland produces a distinctive type of ironstone/boulder opal. It usually shows unique markings in addition to bright traceries of precious opal. To me the markings often suggest traditional Aboriginal art. This piece has light background figures along with bright blue/green veins of precious opal that blink on as the stone moves in the light. Highly polished front and back. It measures approx. 12 x 23 x 4.1 mm. in a pear shape. (Some care, N)
