I believe I purchased this a few years ago at Tsutsumi. I don't have a receipt, so the details are vague. It has a K10WG hallmark. These are large earrings with a strong presence. They are lightweight and very comfortable to wear. I've only tried them on since I bought them. I checked the Tsutsumi website and found a similar design. Size: Height 2cm x Width 2cm Width 5.5mm These are hoop earrings with a diamond-cut finish. They reflect light, allowing you to enjoy a delicate sparkle. The simple two-row design has a moderate volume, perfect for accentuating your outfit. They are recommended for both on-duty and off-duty occasions.
