Material: Platinum Size: Size 10 (Japanese size) Stone: Diamond This is a diamond ring with a 4°C appraisal certificate. I purchased this to wear with an eternity ring I already own, so it is not an engagement ring. Please rest assured. There are no engravings. Only the original engraving is present. However, this item is of a class that should be used as an engagement ring, and it is more often used as an engagement ring than a fashion ring. If you look at the appraisal certificate, you may understand its brilliance, but the sparkle, color, and cut are all of a high grade. It is a round brilliant cut, so the sparkle is different. It also comes with a box, so it can be used as a gift. I am still hesitant to sell this, but I have decided to let it go because there is something else I want. Please note that I may suddenly cancel the listing if there are no bids.
