Tiffany & Co. Silver Heart Padlock Necklace

Elegant silver heart padlock pendant on a 36 inch ball chain. Iconic Tiffany & Co. design. In good condition, with normal scuffing of the silver (see photos). Current cost of the chain alone is 360$. Padlock appears to be discontinued. I assume it would be well over 500$ at this point. I purchased at Holt in 2013. I have the receipt, which I can provide with purchase, along with a small Tiffany bag. Selling because I haven’t worn in about five years, time to go to someone who will appreciate it.
