DP has said he would like to understand my taste in rings. 
I've never been to a proper jeweller before, and I am a sucker for anything pretty, which makes the thought of choosing one thing hard. I'd love to go to a jewellers that stocks a really wide range of diamond and gemstone jewellery where they're patient enough for me to try a tonne of stuff on. From looking online I think I like asscher cuts, three stone rings and halo rubies or sapphires, but we really want to be able to see them on.
Does anyone have any recommendations? I had thought we could just rock up to Hatton Gardens (or Burlington Arcade), but I've looked at a few jewellers' websites and they all seem to require appointments.
Thank you!
