I love some of the designs they have for their cheaper jewellery like the bracelets, pendants etc and I think they're not too badly priced. I don't have any of it but a few friends do and it seems to wear really well without any issues.

Like Onyx said, they have a huge mark up on "the good stuff". No way in the world I would ever buy diamonds from them. One of my SIL's bought her engagement ring at T&C and oh my goodness what they paid for it is obscene given its size and quality.
