Holy COW!!! 20.32ct Queensland Boulder Opal!

Don't blink, or you'll miss this amazing opportunity to own a real Winton matrix boulder opal from Queensland, Australia! The unique formations of the matrix curve and twist in a dance locked in stone accented by pops of green, purple, and gold play of color from the opal held inside its structure. This large example measures a whopping 29.7mm x 16mm x 5.9mm and will look amazing in any setting you put it in. Untreated!!!
