Tiffany authentication services?

[kolibriszuka]

Hi everyone, I'm trying to get rid of a couple pieces of Tiffany silver I don't really wear anymore (two necklaces). I figured I'd list one on EB this week and one next week. The one I listed yesterday was removed for trademark infringement, even though it is absolutely authentic.

I think it was because I included photos of EVERYTHING in the auction (box, care card, ribbon, pouch). Not sure, though because EB won't tell you exactly.

Anyway, the EB employee I spoke with suggested an authentication service that provides a certificate of authenticity. The problem is; there are no jewelry specific online authentication services that provide Tiffany authentication. Does anyone know of one? Will mypoupette do it?

I'm lost here, and I would like to sell the necklaces, but if EB keeps pulling them, I guess I'll just keep them. Any suggestions would be helpful!
