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.
All good
The consultation appointment was really good. They took their time with us, we were able to ask all questions before deciding on a ring. The price/quality ratio is as good as advertised.

I wrote the sales team during the evening and I was quickly helped by Toni. It was a splendid service to have my bracelet sent one month earlier and it fel as he went the extra mile to help me without having to wait days for an answer. I literally got helped within one day.
excellent customer service
In buying expensive jewellery, a man needs assistance and efficient service. 77 Diamonds gave me this; specifically Cecilia Rotar, their Online Sales Specialist. My Wife's gift is now sorted, thank God too, and because of assistance and efficiency from Cecilia, well done.
Very helpful!
Amazing engagement ring
Amazing ring, fantastic customer service and delivered quite fast.
Prior to visiting 77diamonds, I was looking on many other websites, as well as local jewellers. I didn’t like the options so a friend suggested visiting 77diamonds. It’s amazing to see how many different types of rings there are. After customising and paying, I had to make a small adjustment and the sales team was very helpful and immediately had the ring size adjusted. The ring was delivered just in time.
I can really recommend buying an Engagement ring with 77diamonds
Outstanding ring and exceptional customer support
I bought an engagement ring from 77 Diamonds and I couldn’t be happier. The ring is perfect, gorgeous, and very well made. The packaging was also elegant and nicely presented.
I would especially like to thank Raul Berciu for assisting me throughout the process. He provided detailed same-day answers, was extremely helpful, and made the whole experience feel truly premium. Honestly, it was the best customer support I have ever experienced, truly on the level of a 5-star hotel.
I couldn’t recommend 77 Diamonds and Raul Berciu enough. A fantastic experience from start to finish.
Nice product but late delivery

really liked the packaging. Also I would like to mention great customer
