Not All Opals Are From Australia
Balanced carefully on a corner, it looks like an odd shaped aquarium with an underwater scene. Blues, greens, pinks and golden colors bouncing the light within.
This is the Contra Luz Opal, discovered in Opal Butte, Oregon. It weighs approximately 119 ct. and was recently sold at Bonhams for $20,000.
Opals are found in the US too.
