Purchased second-hand from a Nagoya brand shop about two years ago. Size 17. It has genuine diamonds, but one diamond was missing, so a similar one was added. Therefore, it's not a full set of original diamonds, as one is an aftermarket diamond. Please understand this. Because of this, the price is lower than the market price. A receipt from the purchase location (with the amount blacked out) can be included. (See image 8) Due to the high value of the item, cancellations after purchase are not accepted, including for reasons such as switching items. Please make your purchase after confirming the details.
