Thank you so much for the long reply! It is tough, it's totally depends who you talk to because my family think I'm nuts for going with tiffany as they keep telling me- you can find the exact same thing in Hatton garden! But I don't think you can... it just doesn't seem the same. The thought of buying a replica gives me a similar feeling to when I almost purchased a fake designer bag when I was in Thailand haha! I think if I was going to go non Tiffany it would have to be with the mindset of not trying to copy them!
I think when it comes down to a it I'll probably just go with the one that I like best in person because really once this obsession calms down (and I am obsessed!) I probably won't even remember the specs. Which wedding band are you going for/have you gone for? I was completely convinced I wanted a plain band but now everyone saying the channel looks good has got me thinking about the half circle 2mm channel from Tiffanys...
