Platinum 900 Ring with Floral Motif and Diamond Stone Decoration The ring is warped! - Material: Platinum 900 1 carat diamond - Design: Floral motif - Engraving: P900 1.00 It weighed 5 grams on a household scale. See the images. I don't have anything to measure the size precisely. I think it's around size 12-13... This is a personal item, so I haven't had it polished. I will polish it carefully with a cloth and package it. It's warped, but the bottom part isn't visible when worn, so it might not bother some people, or it's suitable for someone who will have it repaired. Thank you for looking.
