Tiffany's Infinity Necklace. I received this as a gift, but I'm selling it because I don't use it! I've only worn it once. There is some blackening typical of silver, but I think it can be cleaned up with care. I will include the box and dust bag ※ The purchase date is also written on it. I'm using "Anshin Kantei" (Mercari's authentication service) because it's only available with "Rakuraku Mercari Bin" (a shipping option), just in case. ※ If you want the box and dust bag, please comment as it will be an additional charge because the box exceeds 3cm. If you purchase immediately, it will only be the necklace. The first photo is from Tiffany's HP for reference. The second photo is the actual product!
