Hi there, I run a service where I connect marriage proposers to a range of jewellers who are suitable for their budget and the style of ring they are looking for. It's completely free and I work with the proposer/couple to help them get the very best value for money when buying diamonds. Hatton Garden can be an intimidating place, and it's not necessarily the best place dependent on the style of ring you are looking for. Please ask him to email me on:
rowena@askherfriends.com and i will connect him to the best people.
Best Wishes,
Rowena
