We’ve purchased our wedding and engagement rings from 77D and we’re very happy. We were well looked after by Tarek and Steffi throughout - excellent customer service.

Awesome client support

Choosing the right ring and diamond for my engagement was very straightforward. The ring looks wonderful and we got a lot of compliments for it. I opened some requests by E-Mail which were answered quickly and professionally (thanks Clare and team).

What can I say... world class

What can I say. 77 diamonds gave me world class service. Wanted to change the order half way though and without hesitation and on a sunday evening at 8pm they responded. Bijoux how i was dealing with replied to all my emails with kindness and service at the heart of them. The ring itself is beautiful. Couldn't of wished for a beautiful ring. My partner will love it and can wait to pop the question with the ring in my hand.

Im sure if I need after sales care they will be as good.

Thank you Bijoux and 77 dimonds

I had a wonderful experience with Toni at 77 Diamonds. She was incredibly helpful, patient, and knowledgeable throughout the entire process. She took the time to understand what I was looking for and selected beautiful options that made the decision so much easier. Her communication was excellent and she made the experience feel very personal and special. Thank you, Toni — I truly appreciate your support!

Engagement ring - lab grown diamond custom make

Hollie & Lulu have provided an exceptional service with great and clear communication throughout the entire process, with regular updates on the order. The price, customisation and range of products have all been excellent, and with a discount the price was easily the best I found, and still for a quality product.

Very good experience from the initial consultation to my jewellery delivery. Agy was very helpful in explaining adequately to get what I really wanted. The ring also came a week early. Very good experience with 77 diamonds

Clare was amazing!

Clare helped me through the entire process and was beyond helpful going above and beyond making everything so smooth and without worry. I also was notified through constant communication about every update regarding the ring and am SO pleased with it! 10 stars for Clare!

I recently returned to 77 Diamonds to…

I recently returned to 77 Diamonds to replace my wife’s engagement ring and wedding ring. When I first bought them years ago, I couldn’t afford the quality I ideally wanted for her, so this time, I wanted to get it absolutely right.

From start to finish, the service was exceptional. The team were friendly, patient, and never once made me feel rushed or pressured. They took the time to walk me through options, answer questions, and genuinely help me choose the perfect pieces.

What impressed me even more was that they later price-matched against one of their own future offers, without me even having to push for it. That kind of honesty and customer care is rare. Even though I felt the price for everything was very fair. So much so I brought some accompanying earnings to go with the set.

I left with a stunning set of jewellery that my wife absolutely loves. The difference in quality is clear, and the entire experience felt effortless and reassuring.

Highly recommend 77 Diamonds, great service, fair pricing, and beautiful craftsmanship.

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!

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!..
