MDC Diamonds was the perfect fit for what we needed. Extremely professional, prompt in answering, and also very thoughtful in making sure I received it in time and the exact stone that I wanted. I'd highly recommend MDC because they are personal and value their clients on an individual level. Moishy was awesome

Moishy was extremely helpful, made some suggestions for a setting that I really wanted and found the perfect stone to complement it. I have been looking at rings on/off for two years and have contacted and researched prices on all the major online retailers… believe me when I tell you.. you get quality, value and excellent customer service experience with MDC!!!

The experience with MDC diamonds has been nothing short of exceptional. I wanted a design that no one seemed be able to replicate for my anniversary upgrade. They not only had the setting I wanted but they also found me a bigger and better center stone within my budget. I could not be happier with the quality of the final product. David and Moishy were responsive and easy to work with and I appreciated the real time text communication. I am now a customer for life and will be referring friends and family.

What a perfect experience I had with MDC Diamonds! My custom ring turned out to be exactly what I wanted, and the entire process was easy and efficient thanks to Moishy’s expertise. He helped me to modify a setting that had caught my eye on the internet, while taking care to maintain the design aesthetic of the original. My new ring is truly a thing of beauty - impeccably created with the artistry and craftsmanship of a true jeweler. I could not be more pleased with the ring and with MDC Diamonds NYC.

I’m very happy I went with MDCDiamonds NYC for my wedding band! They had the perfect style that matched my fiancé’s band aesthetically while also including some things I wanted out of my ring. Ordering was easy and the browser chat is quick and responsive to questions. Once I ordered, Moishy reached out by phone and was helpful and accommodating about customization and shipping. The ring looks great, the inscription turned out lovely, and it fits perfectly. MDC has my recommendation!

Moishy and MDC Diamonds literally saved my engagement and made my, and my now Fiancee's, dream come true. I had been searching for a jeweler for a few months and contacted over a dozen places from different states and in the UK as I was traveling. Funny enough one of the local jewelers I was getting quotes from let it slip that they'll source the diamonds from a company called MDC, so I decided to look them up them and saw they offer custom jewellery so I reached out and I'm really glad I did! Moishy sent me an email and we scheduled a phone call. When he asked me about the budget I was naturally apprehensive because literally every other jeweler I talked to would ignore my budget and insist on quoting me more - which was very frustrating. To my surprise Moishy laughed at my budget and said there's no way it would be that much, probably half of that. It was refreshing and the first hint of honesty I got dealing with Jewelers during this whole ordeal. He was very helpful and patient with all my questions, back and forth on the design, diamond and metal options, and timing constraints. Luckily, since they do everything in-house, they were able to turnaround a custom engagement ring with 2 wedding bands, in at least a third of the time other jewelers. My now Fiancee wanted a very specific design, very symmetrical and with a niche center stone, and they were so patient and helpful with creating a design mock-up based around the example design and the stone we sent to them, and making endless trivial tweaks. In addition, my fiancee's sister had surprised us with her late grandmother's wedding band to use diamonds from, which my fiancee had no idea about, and they were willing to help pull the diamonds from that band and incorporate it into the design and size everything just right around it. Moishy was upfront in warning me that there is always a risk with heirlooms and that they can easily crack, but luckily they handled them with care and were able to extract them al

MDC Diamonds created the perfect engagement ring for my fiancé. They listened to our wishes, found the right diamond and customize a gorgeous piece of jewelry exactly to our liking. Communication was easy and the design was within our budget. I highly recommend them for your needs. I look forward to working with them again for the wedding bands

Was very hesitant to work over the internet and with a long distance jeweler! But, it turned out to be a great experience with Moishe at MDC. A local jeweler had quoted a similar price to reset diamonds in a new setting, but when it came down to finalizing, the local jeweler increased their price by nearly 40% because “gold had gone up”!Moishe didn’t pull that stunt on me. After vetting MDC as best I could and seeing all of the positive reviews, I made my decision to go with Moishe and so glad that I did. Great communication throughout! Just received my ring and I am so pleased❤️
