Natural Diamond Ring [Product Details] * Gemstone: Natural Diamond * Carat: 0.312ct * Grade: SI-1 * Material: pt900 * Ring Width: Approximately 4.0mm * Weight: Approximately 4g * Ring Size: Approximately Size 10 Personal Engraving: None Accessories: None (Ring only will be shipped) (Carefully packaged and shipped) I received this as new, but it was a little too big, so it's unused. It's a beautiful diamond with high clarity. Since it uses 0.3 carats or more, it has a moderate presence and is cute to wear on its own, and it's also easy to match with your existing jewelry, so you can enjoy coordinating. ⚠︎ Although there is no appraisal certificate, it has been appraised. ⚠︎ It has been stored unused. ※ Returns are not accepted to prevent switching. Thank you for viewing! Material: Platinum
