Here is a beautiful Koroit boulder opal cab from my mine in Koroit, Queensland, Australia. Yes, it is completely natural. I found it, cut it and polished it.
This great stone was cut from the center of a nut. It's a pretty blue with a nice sparkle as you move the stone.
Yes, I have more Koroit opal cabs - feel free to ask!
Approximate weight: 12.53 carats
