Absolutely stunning 10kt rose gold Ethiopian Opal, champagne and white diamond ring. Please look at all photos and videos, as I don't recall the carat weight. The cushion cut opal does measure approximately 11mm x 11mm, which is about a 3ct stone. There are 20 small white and 10 champagne diamonds, that sparkle beautifully. It is brand new with tag, never worn and is a size 7, which can be resized by your local jeweler. YOU WILL NOT BE DISAPPOINTED!
