I couldn’t be happier with my experience. From start to finish, the service was outstanding and I felt genuinely cared for throughout the process. The engagement ring is absolutely stunning—beautiful craftsmanship and even better than I imagined. Everything was handled professionally, patiently, and with great attention to detail. Highly recommend to anyone looking for something truly special.

i am waiting for my purchase to be finished and delivered but at this time my experience has been very pleasant from the get go. Before placing my order Cecilia has been very prompt and helpful in answering my questions and has since kept me well up to date with the process.
I hope the product is as good as it looks online.

I had an absolutely fantastic service

I had an absolutely fantastic experience with 77 Diamonds when purchasing an engagement ring, and I honestly couldn’t be happier with both the ring and the service I received.

From start to finish, Tarek Alawiye was exceptional. He was incredibly patient, knowledgeable, and always quick to respond to my many questions. Buying an engagement ring is a big and sometimes stressful decision, but Tarek made the entire process feel smooth, clear, and genuinely enjoyable.

I was proposing in Amsterdam over the Christmas break, and Tarek went above and beyond to help arrange delivery at the perfect time, while also making sure I would still have enough time for the free resizing afterwards. That level of care and attention to detail really meant a lot to me.

When the ring arrived, I was blown away — it is absolutely stunning and exceeded all my expectations. Most importantly, my fiancée completely loves her ring, which is all I could have hoped for.

I’m truly grateful for the fantastic service from 77 Diamonds and especially from Tarek. I would highly recommend them to anyone looking for an engagement ring, and we will definitely be returning in the future for more jewellery.

Perfect place to get your ring

Super helpfull customer service, incredible items to select from. The “make your own” is perfect, plenty of options to choose from with transparant pricing. Shipping was also fast, no import fees.

Above all, beautifull ring.

Great experience and even better final product

The whole experience from choosing what ring we wanted to picking it up was great. We had an even spoke with Fannie in the customer service team and change our payment method of which was no issues and done within a few days.

The ring is a work of art and my partner is so happy with the end result, I would highly recommend using 77 Diamonds to anyone thinking of buying a diamond ring.

Toni at 77 Diamonds has been fantastic from start to finish.

I initially enquire about an engagement rind over a year ago, Toni really kept up top notch customer service, checking in every few months.

when i was finally ready to commit to a design she was brilliant with helping me make it as special as possible.

Extraordinary Experience

I had an exceptional experience working with Natacha. She was always available and responded to my messages incredibly quickly, which made the entire process smooth and stress-free. Despite a very tight schedule, the ring was delivered on time, even before our trip to Paris, which I truly appreciated. Natacha demonstrated outstanding service throughout, and her professionalism and dedication made me feel extremely comfortable and valued as a customer. I couldn’t be happier with the experience and highly recommend her.

Needless to say the ring itself looks stunning and left me quite speechless.

Thank you Natacha and Thanks to the 77Diamonds Team for the gorgeous ring!
