How to Verify Genuine MIKIMOTO Products Even if a MIKIMOTO hallmark is present, it may not be a genuine product. If there is blackening at the clasp connection points or if metal parts are attached, it is not recognized as a genuine MIKIMOTO product. In such cases, please be aware that you will not be able to receive services such as thread replacement, M-charm attachment, or other maintenance at MIKIMOTO stores. This necklace has had its thread replaced at a MIKIMOTO store prior to listing and has been confirmed as a genuine MIKIMOTO product. Therefore, you can receive lifetime maintenance, such as free thread replacement and clasp cleaning, at MIKIMOTO stores. Please purchase with confidence. ------- MIKIMOTO Akoya Pearl K14 Yellow Gold Pearl Necklace Choker With M-Charm Pearls: Approximately 6.5mm - 7mm Length: Approximately 35cm M Hallmark, K14 Hallmark Thread replacement was performed at the MIKIMOTO Ginza 2-chome store in November 2025. A new M-charm (K18) was also attached. As proof of being a genuine MIKIMOTO product, I have uploaded a photo of the thread replacement receipt. (I gave it to MIKIMOTO in exchange for the necklace, so I cannot include it. Please check the photo.) Although there is no box, I will include a MIKIMOTO storage bag and envelope. Thank you.
