Great price great jewelleries. Order processed quickly. However the service could be improved better that the appointment is sometimes too limited in time wise, as we wanted to see more samples but... See more

Wonderful experience with Lesia.

Wonderful experience with Lesia.
She made what could have been a stressful last-minute decision feel completely effortless. When we decided to exchange rings at our civil ceremony, time was tight, but she personally ensured everything was completed within a week. Her attention to detail and thoughtful guidance on sizing, weight and width were incredibly helpful. The showroom is beautiful and made the whole experience feel even more special. We are truly grateful for her care and absolutely love our wedding bands.

Amazing product, exemplary service!

Amazing product, blew me away when I saw it in person. The website customization process was very easy to navigate. Updates via email on the progress of the build were very regular and I enjoyed being kept in the loop. The build was completed ahead of the projected time which was a lovely bonus. Would 100% recommend 77 Diamonds for anyone looking to make this very important purchase.

PATIENT, KIND AND EFFICIENT SERVICE

Hi. I live abroad and reached out to Racha for advice and assistance in a purchase. Racha was kind, patient and efficient and I would highly recommend her. I have as yet not received my item so will review again on the finished product at a later stage.

Excellent service and smooth collection in Dubai

I had a great experience with 77 Diamonds from start to finish. The ordering process was clear and the team was very responsive and helpful.

I travelled from Kuwait to Dubai to collect the ring and everything was perfectly organised. The ring was exactly as described, beautifully crafted, and the GIA certification gave additional confidence in the purchase.

Overall a very professional service and a great experience. I would definitely recommend 77 Diamonds to anyone looking for a high-quality engagement ring.

I have received a fantastic service and…

I have received a fantastic service and especially from Holly whose advice on the ring to get was gratefully received. I unfortunately had to return my first choice of ring as it did not fit my awkward fingers properly and Holly was very accommodating and helped me with the returns process and kept me informed every step of the way from the return to receiving a replacement. If you need advice I would be sure to ask for Holly

Can only recommend

Very attentive, supportive and friendly customer service! They made sure the order would arrive in time after I placed the order somewhat late. Would order here anytime again, can only recommend!

Great company to buy a diamond from

Easy to purchase, great prices and excellent communication (from Clare) throughout the purchase process. Arrived much quicker than initially stated, and packaged really nicely.

Excellent service

I ordered a diamond ring and was given a delivery date for a month later. However, I’m delighted to say that when I requested delivery on time for Valentine’s Day, two weeks earlier, Natacha from 77 Diamonds did everything she could to bring it forward. My concerns about the delivery being with Royal Mail were baseless. It came safely the next day. Very good service.

Service was personal and professional

Service was personal and professional. They were able to show me first through email and telephone conversations and then in person (Hannover Square) the items that I was considering. They understood my requirements and price point and appropriately guided me. Needless to say my wife was extremely happy. I will definitely use 77 diamonds again for other jewellery in the future

Thank you Scott!

After a bumpy ride with not hearing back from the sales support for a few days, I was contacted by Scott Wagstaff - who made the entire process extremely reassuring. Not only did Scott apologise for the lack of original response, he worked to ensure I received my ring 4 weeks sooner than the anticipated date! Scott kept me updated throughout the entire process, and my experience with 77 diamonds was a much more positive one as soon I was introduced to them. Thanks again for all of your support Scott - you made my special day possible! 🙏
