Help Me Identify A Tiffany & Co. Necklace?

It’s silver, I’m guessing sterling, and at the end of the fine chain is a double figure 8 heart-shaped design, about 3cm. I can’t provide a picture, but it’s like this: http://i36.tinypic.com/nzm2de.jpg
(sorry about the vagueness/poor quality).
I would be greatly appreciated if you could tell me the design or send me a link.
