Can you buy the tiffany's double heart pendant without the chain?

That is the link to the necklace. Can you purchase the charm(s) on it, without purchasing the chain? If yes, how much would it cost to purchase the charm(s) only? Thanks!
I doubt, cuz it says 'on a 16" chain' but if you wanna know for sure call them.
here's the customer service page for the US.
