i haven't compared the prices between HK and US but definitely cheaper in HK than here in Manila. So whenever u guys go to HK, grab the chance :-)
i never bought myself any T&Co jewelry but my then-bf-now-fiance does. and i don't mind him giving this to me on my birthday, valentine's, anniv or even christmas. hehe. besides, i can keep this as heirloom for my future daughter too. : )
my latest was a gift last christmas from fiance. a set of Return to Tiffany small round tag bead bracelet, necklace and a matching Tiffany Beads earrings.
i also got Return to Tiffany heart tag necklace, round tag necklace and bracelet. another fave is a set of Tiffany 1837 ID lanyard necklace, hoop earrings and a band ring. I got Tiffany Somerset bangle bracelet too from my bro 2 christmases ago.

i plan to get charms in our trip to HK this march. love, love Tiffany and Co!
