Okay, so Plan A was to go to Carats in Ipswich to talk to them about a bespoke ring. However, my friend very recently had her engagement ring repaired there and she was really unhappy with the results (scratches, ring is wonky, fracture still visible) so I e-mailed round at work for recommendations and have been assured by several people that David White of White Designs Jewellery is really excellent. He is also, very conveniently, literally 8 minutes away from where I live. I’ve contacted him to make a date.
So, my new and improved Plan A! I’m very excited indeed, will keep you posted!
