I honestly don’t know much about this ring as I purchased it from an estate sale years ago. Size 7. It is sterling silver and stamped 925. The stones look like they could be real diamonds. They are very sparkly and clear. The center stone also looks most similar to a canary or citrine diamond. I tried doing a reverse image search and the picture at the end of the images is the closest stone that looks like the stone in this ring. It’s a gorgeous, unique piece!
