Excellent Service from Natacha at 77 Diamonds
Excellent service from Natacha at 77 Diamonds.
I recently purchased a loose diamond from 77 Diamonds and was genuinely impressed with the whole experience. Natacha was extremely helpful throughout and, when I asked whether the stone could arrive any earlier, she went above and beyond to help make that happen.
The diamond arrived earlier than expected, which was a very pleasant surprise, and the quality of the stone was exceptional. The website was easy to use, the documentation was simple to access, and the communication throughout was excellent.
What really stood out was the aftercare. Often, once a purchase has been made, that is the end of the process, but Natacha followed up to ask whether I was happy with the diamond. That level of customer service was very reassuring and genuinely appreciated.
I am very pleased with both the stone and the service, and I would have no hesitation in recommending 77 Diamonds. I will certainly be buying from them again.
Happy with purchase

Cecilia Rotar provided an exceptional support. Waiting for the final result, but nothing to complain about. Only things to praise.
Great product quality, service can be better.
I ordered directly through the showroom in Copenhagen. It took 7 weeks before the ring was delievered to me. There weren't any emails to update me on the status of my order which took longer than 4-5 weeks (the expected delivery time).
Customer service are responsive when it comes to calls, emails, and following up with your requests. However, you have to follow up yourself, even the payment receipt I had to call and ask for it to be sent. At the showroom, Ali was patient, and very welcoming. He helped me choose a great ring for my budget. The sizing though was very tricky and I didn't end up with the perfect size, partly because the ring you try on has no stones, so the weight and feel is simply not the same as the real one.
I also expected more "education" for those who are purchasing an engagement ring, but most of the research you have to do yourself online.
Value for money is really good, and the product quality is amazing - really top tier. Can't say anything about the product itself. I am very happy with it, the size is something that can be fixed.

Excellent experience
Purchased a loose diamond from 77 diamonds but needed it quite quickly. Emailed their customer service team, Natacha was absolutely brilliant, clearly communicated that she was going to get in touch with their team elsewhere to expedite dispatch and get back in touch within a set timescale to provide an update. She did exactly as she said, confirmed a speedy dispatch and new delivery date. The gem arrived before the expected date and was tracked the whole way - I live on an outer Scottish isle which makes this whole experience even more impressive. When it arrived the packaging was immaculate and it really felt special. Would absolutely purchase from 77 diamonds again!

Returned for eternity band
We purchased my wedding band and engagement ring via 77 Diamonds website 14 years ago and returned to their website to look for eternity rings. I was keen to price match with local stores as well as get a good match to my engagement ring so I contacted them. Toni’s communication from initial interest to tracking was prompt and thorough and I’m so happy with my new ring which is a great addition to my stack and offered great value for money.
Great customer service
Excellent experience with Maryam Zadeh
I had an excellent experience with Maryam Zadeh at 77 Diamonds Manchester. She was extremely knowledgeable, patient and attentive throughout the whole process, helping me shortlist the right diamond and ring design with genuine care and professionalism. Her guidance made the experience feel very personal and reassuring, and I would highly recommend her to anyone looking for expert advice when choosing a special piece of jewellery.
