Ultimate Diamond Co Reviews

If you are looking for a business that’s going to uphold the best professionalism, service, and quality every time you walk through the door then Ultimate Diamond is the place! Aayushi and her team went above and beyond to take care of every single aspect of my customization. She and her manager are the Real Deal. They pay close attention to detail and make sure they understand exactly what you are looking for. As far as providing options, there’s no place that will work with you better. They will show you different customizations, offer you finance options, and follow through completing the order by taking care of any adjustments after the purchase has been made. Aayushi will leave no stone unturned, literally and figuratively. They made me feel comfortable every step of the way which allowed me to create a memorable night for my Fiancé and I. These guys are the best in NYC hands down. 100% recommend.

​I had an amazing experience getting my engagement ring at Ultimate Diamonds, all thanks to Aayushi! She was incredibly patient and helpful throughout the entire process, especially when it came to making tweaks to the CAD design. When I was having trouble visualizing the final piece from the digital renderings, she went above and beyond by using real reference photos to help me see exactly how it would look. I’ve since proposed, and my fiancee absolutely loves it! Her guidance made all the difference, and the ring turned out perfect. Highly recommend asking for Aayushi!

We worked with Aayushi who was very friendly, helpful with decisions, and efficient! She was honest with what looked best and was most practical. She didn’t try to push anything on us and the final price was way below what we expected coming in! She was available via email afterwards for changes and questions. We received the ring before the promised date and it came out beautifully, exactly what we wanted. A really great value for our dream ring. Hoping to come back for our wedding bands! Would recommend!

Billy was phenomenal to work with. He educated me around the engagement diamond process and we’ve worked together to keep my wife happy ever since! His prices were always more than fair and he even helped me to find a watch!

We had a fantastic experience with Aayushi at Ultimate Diamond. We came to her with a design we loved, and she helped us create a beautiful custom engagement ring that was fully tailored to our preferences. Her communication was excellent throughout the entire process, making everything easy and stress-free. When the ring needed to be resized after the proposal, she handled it quickly and free of charge with no issues at all. We couldn’t be happier with the final result and highly recommend Aayushi and Ultimate Diamond.

I’ve purchased multiple Patek Philippe watches through Alexa, and every experience has been exceptional. She is incredibly knowledgeable, professional, and always goes above and beyond to find exactly what I’m looking for. What stands out most is her honesty, attention to detail, and communication throughout the entire process. I always feel confident knowing that she’s sourcing quality pieces and looking out for my best interests. In a market where trust is everything, Alexa has earned mine completely. Every watch has been exactly as represented, and the level of service has been second to none. I highly recommend Alexa to anyone looking to purchase a luxury timepiece. I look forward to working with her again in the future. ⌚

My fiancée and I bought our engagement rings here, and we couldn’t be happier with both the rings and the service we received. Tahir was absolutely incredible throughout the entire process. He is knowledgeable, kind, patient, and so easy to work with. He took the time to answer all of our questions, never made us feel rushed, and was very thoughtful about timelines. He kept my fiancée updated every step of the way, which made the whole experience stress-free and exciting. Almost a year later, he still checks in to make sure we’re happy and completely satisfied with our rings. That level of customer service is rare. It’s honestly amazing how young he is because he carries himself with so much wisdom, professionalism, and care. Thank you Ultimate Diamond for everything!
