Diamond Solitaire engagement ring Newcastle / London

Hi. Can anyone recommend where to buy a cushion cut large diamond ring? Do the high street shops like Goldsmiths have stunning special rings or any other suggestions? I’ve looked online and nothing stands out.


I’m not in uk so can’t just pop onto shops but I’ll be back soon and based in Whitley Bay / Newcastle area and will be travelling to London for my fiancés chemo treatment so could look there.
