Thank you for viewing. Weight: Approximately 5.0g (measured with a household scale in 0.5 increments) Markings: Pt900 1.064 Size: Size 12 Round Brilliant Cut F Color SI2 Good Blue With Appraisal Certificate The F color, a bridal color, The large, over 1-carat diamond has a wide table surface and emits a strong, rainbow-like brilliance. It is a very beautiful ring. It was newly finished at a jewelry store a few months ago. (There may be minor scratches from being tried on since then) The diamond's brilliance reflects on the beautifully mirror-finished metal, making it even more beautiful and radiant. High-quality, large diamonds of 1ct or more have not only the value of beautiful jewelry, but also the appeal as an asset due to the current weak yen caused by imported goods and the rise in platinum prices. In my subjective opinion, the current listing price is about half the market retail price. (This is just my subjective opinion) I took the photos under LED light and natural light for the listing. I have not edited or adjusted the colors in the description. The colors may vary slightly depending on the angle of the light. The actual product may look slightly different from the photos depending on your computer, mobile phone, or tablet. Please understand.
