Australian Boulder Opal & Diamond Ring

Write a Review

This is a really beautiful, natural Western Queensland Australian Boulder Opal in an 18K rose gold setting with over a carat of large, best quality diamonds (it really makes a difference). We also put a split shank on the sides (comprised of diamonds of course).

Boulder opal is distinguished from black opal as it has a backing of ironstone. The ironstone is naturally occurring (not added) and stabilizes the opal.
