Size 5 / 18K gold/ triple excellent diamond/ engagement ring

Size: 5 - Carrot weight: 0.31 - Ring material: 18K white gold - Setting: Tiffany's nife-edge style solitaire - Diamond spec: GIA certified natural triple excellent round cut diamond. Colorless F, Si1 clarity I adored this ring as my first diamond ring. It's simple but classy. But since upgrade my ring, I rarely use it. I bought this from luxury wedding jewelry store in South Korea, so the setting and craftsmanship is perfect. I have original brown leather ring box and the ring box from Tiffany, so you can opt the box. Please do not ask for discount. We know this is a good deal😉
