This ring is an open cut weave band ring with a marquis shaped diamond cluster. You can see from the photos the Hallmark is there, but when I had it sized years ago the karat gold marking was blended out in the gold. My jeweler suggested I sell as 10k just to cover my bumm. It very well could be 14k. He wouldn't guess. I didn't want it scratched up from testing. The diamonds are all there and have a lot of sparkle. Size is shown in photos.
