A ring with a three-prong setting for a heart-shaped stone. The small prongs make the stone's sparkle stand out. I believe it's cubic zirconia, but if you told me it was a diamond, I might not be able to tell the difference... it's very beautiful. Since there seem to be different grades of cubic zirconia, I think this might be a higher quality one. The ring has a "9k" stamp. 9k white gold. The band is thin and sleek, which makes the stone appear larger. Professionally cleaned at a jewelry store. #4℃ #StarJewelry #VendomeAoyama
