Lovely, with minor notes
Nice Wollo opal. Slightly smaller looking than I pictured at this carat weight, but the color makes up for it.

Stunning in person
I was nervous about buying a gemstone online, but the detailed specs and macro photos matched the stone exactly when it arrived. Couldn't be happier.

Even better than the photos
My jeweler was impressed with the clarity and cut when I brought this in for setting. Will absolutely be back for my next piece.
