Tiffany & Co. Diamond Bezel Necklace Platinum 18k Yellow Gold

This necklace was given to my mom in the early 2000s by her then-boyfriend who ended up being a terrible person (lol). I'm selling it to fund my first home purchase! It's in great shape-- literally has been sitting in a jewelry bag since 2005. You can see in the 3rd photo the little Tiffany logo. I'd love for someone else to enjoy this!
