Purchased 4 years ago for 13,800 yen, used only twice. The stone's cut is a bit unique. While it doesn't have the warm-toned light of moissanite, it does have an interesting sparkle when exposed to sunlight. It's a zirconia of a slightly higher quality. The size is also elegant, making it easy for women to wear. There is no discoloration or deterioration, and the condition is very good. To remove it, hook your nail and snap it open, then snap it off with your fingertip.
