I liked Tiffany's years ago, but to me, the brand allure is gone.
I have the T bracelet, the wire is flimsy. It is poor quality compared to my other jewellery (Cartier, VCA, etc), so I will not buy Tiffany again. Their in store experience doesn't feel like a luxury shopping experience.
The quality behind the European jewellery houses (Cartier, VCA, Bulgari, Boucheron, Chaumet etc) has really proven itself to me. There is something different about these jewellery houses which have been around from the 1700s and 1800s, knowing they have perfected their technique over so many years.
I would rank all the European jewelry houses as 1st tier and Tiffany's as 2nd tier. It is a shame as I like their City Hardwear and T collection but I will not buy them because of the brand, and their pricing doesn't reflect their market position.
