Take a look at this 20.78ct Queensland Boulder Opal!

This is a highly figurative example of 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 cobalt blue play of color from the opal held inside its structure. This large example measures an impressive 23.7mm x 23mm x 5.2mm and will look amazing in any setting you put it in. Untreated!!!
