Approximately 9 years ago, I purchased this one-of-a-kind designer piece at a customer event held at a separate Festaria venue. I've only worn it once. * Original price: ¥300,000 (Photo 10 is not provided due to personal information. It is included as proof of the original price.) * Size: #11 * Weight: 7g * 25 diamonds * Comes with a quality assurance certificate * Includes a special box and scope * Ultrasonic cleaning performed at the store in late October ※※ Due to the high value of this item, please examine the images carefully to avoid any issues. Shipping will be via standard Mercari delivery, as the "Takkyubin Compact" option doesn't offer sufficient insurance. I'm hesitant to sell this, so I'm open to a slight price reduction.
