This is a K10 white gold half diamond ear cuff. It is sold out online. I believe it is in beautiful condition with only a few wears, but please consider it with an understanding that it is a used item. I do not have the warranty or receipt, but it is a genuine item purchased from an authorized retailer. Please check the Hirotaka logo engraved on the ear cuff itself. It will be sent in the original case. Returns are not accepted.
