Very bright beautiful, I can't help imagining an Australian white opal of this size and color, you would need a second mortgage to own it, the only difference is you shouldn't get it wet for extended period of time. I have now sold literally thousands of opals and only a couple complaints of chafing. Large oval white  fire opal 16x23mm 18cts. Mounted on a large simple solitaire solid 14k gold ring, I like the simplicity and solidness of this ring. It's heavy for its size.
