This is a 4°C 10K pink gold diamond ring (size 10). Retail price: ¥56,100 (tax included) This ring has a delicate and feminine image with gentle curves and flowing diamonds. The soft twist creates a beautiful, elegant cross line. The diamonds sparkle prettily along the flow. The soft shine of the pink gold is also beautiful, a sophisticated design. Item number: 111036143103 Material: K10 pink gold Stone: Diamond Carat Total: Approximately 0.09ct Size: 10 Engraving: 4°C K10 K10 is recommended for everyday use as it is harder and more durable than K18. It has hardly been used, so it is a beautiful item that is almost new. I think you can use it comfortably as it is. I plan to ship the item itself via Yu-Packet, but I will include a 4°C ring case for an additional ¥800. If you wish to have the case, please comment in advance. Thank you for your consideration.
