Great experience and ring!
I am absolutely thrilled with my experience at 77 Diamonds! From the moment I visited their beautiful showroom, I knew I was in good hands. The staff was incredibly helpful and professional, responding to all my emails promptly and making the entire process stress-free. The speed of service was impressive, and I received my ring much faster than expected. As for the ring itself, the diamond is simply stunning and the craftsmanship is perfect. I couldn't be happier with my purchase and highly recommend them for their quality and top-notch customer service! Order 460680

Amazing support
I placed my order a little late, but after contacting customer service, Stefana did everything she could to ensure I received the ring just in time. Unfortunately, the ring was a little too big and the engraving wasn't perfect, so I contacted customer service and made an appointment in Zurich. Lorna was very friendly and eager to solve our problem. After the size adjustment and engraving correction, we are completely satisfied. Thank you very much!

I am absolutely delighted with the service at 77 Diamonds especially with Let Delgado.
From the very beginning, the communication was extremely professional, friendly, and reliable. Let took the time to explain everything transparently, was always approachable, and handled a time sensitive situation with complete confidence and calm.
You can immediately tell that you’re dealing with someone who combines real expertise, experience, and high standards with genuine care and professionalism. That level of service is exactly what you hope for when making such an important and emotional purchase.
Thanks to Let, everything went smoothly and stress free, and I felt well taken care of at every step. Truly top-tier service highly recommended. Thank you for the outstanding support!

I was looking for a special gift in a relatively short timeframe, and contacted the customer team to understand my options. Floriana came to my rescue in helping me find something that was just right. She explained the process fully and assured me that the item would arrive on time, which it duly did. I am grateful for her guidance in selecting the piece and for her assurances. Very happy with the item. Great purchasing experience and great customer service.
