This is pretty spiffy: you can enter to win an 18k gold Charriol bracelet worth $1,750 from
Luxury Bazaar's 2013 Holiday Giveaway. You sign up with a Twitter, Facebook, etc. account and each like or share you do adds another entry, so you can improve your odds that way. I just thought this was a really nice bracelet, would make a perfect gift for the lady in your life (or yourself if you are a lady!
)
I've also found another contest, for a Cartier bracelet worth I-don't-know-what-but-probably-lots. That's at the
Cartier Holiday Giveaway by a shop called Opulent Jewelers, and works the same way as the contest above - you enter with Facebook, Twitter, etc, and can get more than 1 entry.
