I've said it before, but I had great service from 77diamonds.com. Great prices, great service, great choice. The people on the other end of the phone really know their stuff and the website is brilliant. Choose your stone, set sliders for criteria, view the cert then choose the ring. Pricing really transparent and really quick to deliver with great comms all the way through. They also have a showroom just off Oxford Street so you can make an appointment to go see them.
I'm aware the above reads like an advert but I really did find them to be excellent :lol:
I did a lot of real and virtual legwork before I settled on them. The thing I like is that you can exactly choose your stone rather than most jewellers that, if pressed, will say "well it will be somewhere between a VVS and SI, somewhere between a J and a G" and so on. But then I'm fairly analytical and wanted to ensure I knew exactly what I was getting and was getting the very very best for the cash. It appeals to the control freak like me :)
