Emma & Cecilia were great!
Emma & Cecilia were a great help to me with purchasing my diamonds. Fast, honest, and helpful service!
Great products and support
Great quality products, and a very happy partner with their gift. Website is really easy to use and shows you exactly what you’re getting. Prices are really reasonable, and you do seem to get a lot for your money compared to other sites. Finance available too which is great.
Customer support was excellent, and even managed to get my order a bit quicker in time for an anniversary. Friendly, helpful, and overall a great experience.
Great experience all round
I had a fantastic experience dealing with 77 Diamonds, in particular Clare Caliwan who was amazing throughout. Helpful and really quick responses to emails. The ring I ended up with is great and for a very good price. It needed resizing and this was very easy to get sorted. Highly recommend 77Diamonds
Fantastic all round 👍
Fantastic product, came as described and on time, and the service was very supportive throughout the purchase. Highly recommend 👍
I loved the service and the product
I needed a specific wedding ring in a very short time and thanks to Toni, he made it possible for everything to be perfect. I love the ring, it's in platinum just like I wanted and the size I asked and everything made in a very short time. I appreciate his efforts to make it happen. I'm very happy with my purchase and the experience that I had. Thank you ☺️. The service was awesome and also the product, if I'm ever going to buy another ring I'll come back here.
Great customer support
My order came quick and looked perfect. I received great support from Tarek Alawiye, he replied really quick and answered all my questions about the order and delivery.
100% satisfied customer
The selection and ordering process was clear and well laid out and the pricing was good. After ordering I was told delivery would take about 4 weeks which would be after the wedding and it was a gift for my best lady so that was not good news but first Natacha and then Clare provided outstanding customer service, ensuring the diamond earrings arrived 2 days before the wedding and kept me informed at various points to make sure I knew what was happening.
When they finally arrived, I didn't want to open them - the packaging was exquisite! I did finally pluck up the courage as Clare was keen to know if I was satisfied with them and OMG... was I satisfied with them! More importantly, my best lady was blown away! She literally removed the Tiffany earrings she had already put in and wore them throughout the wedding day, overnight and again the following day - she didn't want to take them off. Absolutely fabulous earrings and service - could not rate them more highly - and trust me, I'm very fussy - and so is she! Thank you 77Diamonds x
Great communication and great…
Great communication and great assistance. 100% recommend working with Cecilia Rotar
Fast delivery, great quality, superb customer support
I ordered for the first time at 77 Diamonds and had an issue with the delivery timeline - Natacha was able to resolve my request and I received my order in time. Natacha was super friendly and I am more than happy with her customer support! When my order arrived I was soooo happy with the overall quality of the earrings - 77 Diamonds gained a new longterm customer!

The ring was very nice, The delivery was dispatched exactly on the date I was told, and it arrived next day.

Very warm welcome and professional sales team! Would definitely recommend!
Very satisfied with this purchase
Very satisfied with this purchase. The delivery was faster than expected, and Clare was very helpful in keeping me updated about the product. Thank you!
Fantastic customer care.
I recently placed an online order with 77 Diamonds; a beautiful eternity ring that I intend on gifting my wife for our 10 year wedding anniversary. I'd previously purchased the engagement ring and wedding bands with them and wanted to ensure they matched.
However, I mistakenly overlooked the anticipated delivery date which was much later than the date I intended to gift the ring.
I emailed customer service to enquire whether a speedier delivery was possible and the same day I received a response from Clare Caliwan in the Customer Care team.
Clare advised that she would contact the workshop to see what could be done. Over the next few days whilst we waited for an update (bank holiday weekend), Clare made sure to keep me posted, and once an update was available, she then went above and beyond to ensure that the ring would arrive in time.
It was so refreshing to deal with a customer care assistant who seems to truly understand what it means to take care of your customers.
Thank you so much once again!
I will continue to highly recommend 77 Diamonds to anyone looking to purchase something special for a loved one.
great product and service
Delivery,product & service were all great. Tarek Alawiye was great from start to finish. Used them twice no complaints.
Great customer service and really amazing response times
Chose this company after reading a recommendation on Reddit. Really happy with my purchase and the clear communication and customer service I received throughout. I think I placed my order for my wedding ring three weeks ahead of my wedding date and the estimated delivery date I was given was the day before (fine!). Replying to one of the updates I then requested a slightly earlier delivery date to ease my nerves which Natacha sorted for me really quickly and with no fuss. She then followed up to make sure I'd received my order and that I was happy with it. All in all really happy with my experience.
Amazing experience
I had such a great experience ordering from here, I needed my order a bit sooner and Clare from customer care went above and beyond to help me! my experience couldn’t have been any better thanks to Clare.
As well as the packaging was so lovely and the ring was everything I was expecting and more! would definitely recommend 77Diamonds!
Amazing service
Amazing service. There’s always a bit of nerves and apprehension when ordering such an expensive, valuable, sentimental piece of jewellery. 77 Diamonds could not have been any better.
I placed my ordered then when i received my delivery date, it was later than I needed to make sure i had it in time for my holiday. I paid the express priority to make sure I got it on time and it came the day after it had been dispatched.
Special mention to Clare who had helped me throughout the whole process and took the stress away from me. I had my special moment which i will always remember, thanks to 77 Diamonds.
