This is a Christian Dior necklace. Purchased from a brand-name antique market for businesses. The item was purchased after authenticity verification, and is a genuine product that has undergone a double-check by an appraiser with an antique dealer's license. As this item was purchased at an antique market, the purchase date and frequency of use are unknown, so please make your judgment based on the photos and description. Since this is a used item, please refrain from purchasing if you are sensitive to such things. I will consider price negotiations only if you follow me, but please understand that I may not be able to meet your request. Generally, I offer a 5% discount. BIV7980…11
