Purchased at a jewelry store, this is a K18 natural pearl tie pin. It is a new, unused item. 4.4 grams Both the main body and clip are stamped K18. The jewelry store stated that everything except the spring and pearl is K18. A high price was offered at a買取店 (kaitori-ten - a store that buys used items), so it has been appraised. This is a valuable item, both as a tie pin and as a gold item. Due to the current surge in gold prices, I will not be offering a significant discount. Please be reasonable. As this is a high-value item, I will record a video of the packaging and shipping process. This is to prevent any trouble such as damage or theft. Thank you for your understanding.
