Tiffany & Co. Sterling Silver Heart Tag Necklace

I got this as a gift so I’m not sure if it’s 100% authentic or not. I’ve had it for many years now and it’s still beautiful and in clean condition. This is a Tiffany & Co. sterling silver necklace with a heart tag charm. It features a signature turquoise-coloured heart pendant. Includes original box and polishing cloth. Comes with polishing cloth so it’ll last forever! Pickup in AJAX
