Does the style of ring affect my ring size?

Rings which have a deep band width will need to be slightly larger than your normal rings so consider this when checking your size.

What if my ring is too big or too small?

If you find that the ring you've bought from us is too big or small, just take it along to one of our showrooms. We'll either re-size or exchange it, to make sure you always get the perfect fit.
