From engagement to eternity - outstanding Service and a beautiful surprise!
I recently purchased an eternity ring from 77 Diamonds and, once again, they exceeded my expectations. The ring was due to be ready on 8th December, but I emailed Clare Caliwan (Customer Care Advisor) to ask if I could collect it earlier while in London on 4th December with my wife. Clare went above and beyond to make this happen—she expedited my order and arranged a convenient time for me to collect the ring from their London office.
The experience was truly memorable. Clare was personable, attentive, and worked hard to accommodate my short-notice request. This is the second time I’ve used 77 Diamonds, having purchased an engagement ring and wedding band from them 10 years ago. My wife now wears all three rings and couldn’t be happier.
Thank you, Clare and the team at 77 Diamonds, for your outstanding service and craftsmanship. Highly recommended!
Tarek Alawiye
Not the first time I have used 77 diamonds, this time being my fourth.
Tarek Alawiye went above and beyond to ensure my wife will receive the beautiful eternity ring she yearns for.
They even had her size on record from our engagement, 10 years ago.
Exemplary service as always.

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.

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 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.
