Just the lock charm! Does not include the chain - I have no idea where it went, I think I took it for another necklace and have misplaced. I have the original gift receipt from Tiffany that I can include if desired. Has a spring loaded lock (just pull up on the lock) so you can put it in between a Tiffany chunky chain or on any silver or white gold chain. I no longer wear this hence why I am selling. Will come with Tiffany box. 100% Authentic purchased from Tiffany
