Purchased in 2017 at Takashimaya Nihonbashi. This is undoubtedly an authentic item. I purchased this as a wedding ring, but I can no longer wear it, so I am offering it for sale. There is no personal engraving. The melee diamonds are highly transparent, and the ring sparkles beautifully. Although there is no major damage, there are some minor scratches and scuffs. A certificate with the matching serial number will be included. Please note that due to the nature of the item, returns and exchanges are not accepted. Material: Platinum Stone/Type: Diamond Accessories: Guarantee (Certificate)
