"4°C 4℃ Engagement Ring Diamond 0.520ct Size 11 Platinum Ring" Purchased as an engagement ring. Bought at a 4°C authorized store in Osaka in 2017 for 600,000 yen including tax, but I will give it to someone who needs it since I won't be using it. The ring itself cost about 50,000 yen, and the rest is for the diamond. The size is 11. I will also include the appraisal certificate, so please see the images for details. I wore it once when I went out to eat. Recently, after informing them that I would be selling it as a used item, I had it cleaned and the engraving removed at a 4°C authorized store, so it is clean and has no engraving. Since it has been stored by a private individual, there are some stains on the outer box, etc. Please consider it as a bonus. The crystal diamond-shaped jewelry case that came with the purchase is sparkly and very cute. To prevent switching, returns and cancellations are not accepted. - Shape & Cut: ROUND BRILLIANT CUT - Carat Weight: 0.520 ct - Color Grade: E - Clarity Grade: VS-2 - Cut Grade: EXCELLENT - Polish Grade: EXCELLENT - Symmetry Grade: EXCELLENT - Fluorescence: MEDIUM BLUE - Measurements: 5.16 - 5.17 x 3.17 mm - Table Percentage: 57％
