I purchased this and liked it, but I haven't used it much and have been storing it. It's a very simple round brilliant cut diamond. Although it's a small diamond, it's a high-quality item. I bought it at Ginza Mitsukoshi. Color Grade: E Clarity Grade: SI1 Cut Grade: Excellent Finish: Excellent Polish: Excellent There is no box.
