So we went back to the pushy salesperson shop yesterday to have another look at the rings. Went for one, came out with two! Result!! The pushy lady actually did us quite a good deal, couldn't decide between the two rings, one was much cheaper than the other so she said she'd resize them for free if we got the two, which worked out cheaper than just buying one and paying to resize it. Well, not so much for Mr Babs. But I have two lovely new rings now, I'll have to wear them on alternate days!
