I lost my wedding ring and wanted to get a new one made to a very specific design incorporating some gold of my own for sentimental reasons. I used a place called Ring in Brighton, spoke to them on the phone to get it all sorted then two visits, one to finalise order and work out size the second a week end away on my wedding anniversary to pick it up. Tried it on and size was wrong but all sorted in under 24 hours,
Reason I liked them was because of the advice, I said what I wanted and they told me what would or wouldn’t work and why.
I would have thought you could post the ring to them then make a nice week end away to pick it up.
