Thank you for viewing. This is the Wishing Star Swing Ring. The diamond is approximately 3mm. I believe it's 0.05 carats. It's a swing type, so it adds movement to your fingertips. I think it's in beautiful condition, having been used about 5 times. I hope you like it. - Brand: MARIHA - Material: K18 - Size: Size 9 - Design: Ring with Diamond
