12. ALWAYS check a seller's feedback! Don't simply check their feedback number, but look for past buyers who may have also bought tiffany jewellry from them recently. CHECK OUT PREVIOUS LISTINGS! Today I JUST found a seller who had what looked to be an authentic Tiffany toggle necklace & bracelet set, with a fairly decent story as to why she had these items, so I checked out past items they'd sold. GUESS WHAT? They've sold at least three identical sets in the past month!! Now what are the odds of someone having THREE sets of brand new, never worn Tiffany jewelry? Right.

13. Be suspicious of someone saying they got the item but it's just not their style, the recipient already had one, it didn't fit, their girlfriend broke up with them, etc. Tiffany has a generous return policy that allows returns for items purchased within the past 30 days of the receipt. So there is really no reason for an intelligent person to be selling a new piece of Tiffany on ebay, especially in this economy!

Also, NEVER, NEVER, NEVER buy Tiffany jewlery from someone who keeps their feedback private!! That's a HUGE red flag that they're selling fakes and don't want people, like me, to warn their bidders that the item is fake! (Which I do, when I have time).

14. I am personally VERY leery of people who sell Tiffany Bracelets and necklace sets. People who have authentic items like that will break up the set and sell them separately, to make more money. If the set or their feedback looks shady, it's HIGHLY likely that they've combined a fake set to draw more attention and bidders. In all my time of researching tiffany jewelry on ebay, I've NEVER come across an authentic set. I'm not saying it couldn't happen, just that it's very unlikely.

15. In regards to the "double heart" Tiffany Necklaces I've seen floating out there, be aware that the hearts should NOT BE CURVED in any way, but should be shaped JUST like the hearts on Tiffany's tag necklace and bracelet. ONLY THE LARGER, BOTTOM HEART IS ENGRAVED with Tiffany & Co. The top heart is BLANK! Also, the hearts hang at an angle from the chain, if you're looking at the necklace, the chain should go through the LEFT side of the heart. The fake one's have the chain going through the top of the hearts. Don't fall for those necklaces that have both hearts engraved, or that have "curved" hearts, those AREN'T TIFFANY!!
