I was helped a lot by steffi and her help was invaluable in ensuring that my partner picked out the ring of her dreams
Great customer service!
Clare was attentive and quick to respond. I had a great experience with the time and would really recommend their customer service as well.
Easy site to use
5* Service from start to finish
What an absolutely refreshing experience. The team at 77D went above and beyond at every step of my order. Customer service over the phone was always answered immediately and the help was top class. The jewelry was exactly what I was after on my journey finding the perfect engagement ring and the way you can spec your own ring to your own budget is super simple, easy, transparent and extremely good value when compared to all other high street shops.
Also, i checked all the documents and the diamond certification no. on it (using 30x magnification) and it all checked out, if anyone is doubtful!
After the order i needed a resize and we went to the London showroom for an appointment. After this the we were told 3 weeks for the resize and this date was hit, The resized ring was actually a re-mount and it was again perfect.
I couldn't recommend this company enough if you want a custom and special ring to your own specification and 10/10 customer service and aftercare!
You are guaranteed to receive a great service.
You are guaranteed to receive a great service when you turn to 77D. I purchased the engagement ring from them and more recently a set of diamond earrings for my wife. When I want diamonds I always end up on the 77D website!
Amazing Company!..
What can say about this company apart from what an amazing experience i have had, I have made three orders so far and from the first moment you place your order they go over and beyond to keep you updated, not only that, Tarek Alawiye has been fantastic! He really does go out of way to ensure you receive nothing but pure satisfaction with your order. This is my go to jeweller now and I would just like to finish with a big thank you to them all, you have put smiles on people's faces with some beautiful items and also mine with the great value for money. You will not be disappointed with your purchase!..

Lee was absolutely amazing
Lee was absolutely amazing! Helped me design the perfect ring and even though I was cutting it extremely fine to have in time, she ensured that it was. My fiancé and I couldn’t be happier! Thank you Lee!

Excellent from start to finish
From the moment we booked our appointment, the whole process was easy, relaxed and enjoyable. Before the day, they asked what kind of rings and styles we wanted to see, so everything was ready for us when we arrived.
During the appointment, the staff member was brilliant. He was friendly, knowledgeable and never pushy. There was no pressure to view things out of our price range and he never tried to upsell anything, which made us feel completely comfortable. Instead, they made the experience exciting and special, helping us focus on what truly felt right for us.
They kept me informed on the timeline, where the ring was on production and delivery timeframes. The ring was even ready earlier than anticipated so had communications on earlier delivery.
Overall, it was a wonderful experience and we couldn’t be happier with both the service and the ring

Outstanding quality, service and value
This was my first time buying through 77 Diamonds. I needed a bespoke ring with just two weeks notice and the company delivered exactly what I asked for in the timeframe. Cecilia was my main point of contact and she was outstanding throughout, helping me choose the diamond and expediting the entire process. I travelled to the companies impressive Hanover Square store to collect my order and everything went very smoothly. I highly recommend 77 Diamonds and thank you Cecilia for all your help. Dan

Holly a was very helpful choosing a last minute birthday gift. Initially, I organised to collect the jewellery in person but the team seamlessly organised Royal Mail delivery to my home address.
