When the price of 24-karat gold is around 5,000 yen per gram, I purchased this item for approximately 300,000 yen at a department store. I wore it once for about 2 hours, but haven't had the opportunity to wear it since, so I am putting it up for sale. However, it was stored in a jewelry box, so the original box is not available. Also, the warranty card cannot be found. It will be shipped in a different box. This is a Tiffany classic item, and due to its high value, returns are not accepted after purchase to prevent switching, etc. Please understand. Stamped 18CO750 (see photo 7) The clasp is a spring clip type.
