I bought a piece of jewellery which needed some adjustments to be made. I brought it to JD Jewellers as I prefer proper jewellers to retailers. I had the best advice and service and absolutely cannot fault them. If you need anything these are your people.

Review from my Mum's experience:
'I needed to have my wedding ring removed and wasn't sure any jeweller would be willing to do it, as this service was all I was looking for. I decided to go to Jonathan David having seen the reviews, and rang ahead to check and make an appointment (in line with Covid-19 rules). I was made to feel welcome in a very cosy space, the gentleman who met me was very attentive, kind, and couldn't have been more helpful. He took the ring off without any charge and advised me to not have the ring resized for at least 6 weeks, due to swelling. I asked to look at some rings
