"MDC Diamonds Is a Great Place To Buy Your Diamonds"

After researching and visiting many jewelry stores in the Diamond District, my best experience by far was with MDC Diamonds. David and Rosa were exceptionally courteous and patient as I chose an engagement ring for my soon to be wife. It was a welcomed relief to find an establishment where there was no pressure to buy. David was very helpful with my selection, and I highly recommend anyone who is looking to make that very important purchase to visit them first as well as there very helpful website. When I saw the finished ring for the first time, it had more than exceeded my expectations. My fiancée loves her ring and anyone she shows can’t stop complementing her on how beautiful it is. I'll definitely be going back for the wedding bands.

I would like to thank David and his staff for the outstanding Diamond ring!! I have never made a purchase of this type online before, and honestly my husband & I were skeptical. The 1.01 Karat diamond ring that I purchased is everything that was described to be & MORE!!! The certification from the gemologist accompanied the ring, and it is the "real deal"! I will definitely be purchasing other items in the future & recommend David to everyone!

"MDC is an honest jeweler with great service"

I recently purchased a .86 carat three stone diamond ring from MDC for my wife for Christmas.
I was nervous about buying such an expensive item sight-unseen, but I did a ridiculous amount of research (20+hours at least), both online and brick and mortar stores, and MDC was the place I ended up purchasing from.
I really appreciated his honesty about the quality of the cut of the gem being important. Most other sites wouldn't list their cut grade, they just want to throw the color/clarity/carat weight at you and get you to pay more for a stone because it's bigger, not because it's going to sparkle and shine as if by magic like a master cut gemstone should.
After receiving the ring (which was delivered very securely) I was very impressed. With bright light on it, it was dazzling. The "signature ideal cut" is the real deal, and totally worth it.
The only minor complaint I would have is that the auction listed the center stone of the ring as a radiant brilliant cut, and it actually turned out to be princess cut. I'm not sure what the mix-up was, or if I was reading the auction wrong, but it actually worked out for me because princess is one of my wife's favorite cuts, and when she finally saw the ring, it took her breath away.
Dealing with MDC was a pleasure, and I would definitely do business with them again.

"The Only Way to Go"

I have now purchased three different items from MDC, a diamond/sapphire ring, and two sets of diamond earrings. The ring I had seen in a jewelry store in Las Vegas but since I had no big winnings, was not looking to purchase there.

Shopping with MDC is a great experience because of the selection and the lack of pressure. If you want to look at something else, it is just a click away. Detailed descriptions make it easy to compare.

Normally a jewelry store only has large price differences. MDC has prices for similar items (1.0 carat, 1.2. carats) which help understand the incremental price difference.

Delivery is either overnight or second day air with good secure packaging. No one knows what is in the box. Plus it is fun to open it and look at your purchase.

I've been very happy also with the personal service. You can tell that MDC really likes the business they are in. David does a great job. I'll look forward to buying my next purchase there also.

I purchased an emerald cut and tapered baguette engagement ring from MDC. The ring is simply stunning. Everyone should buy ALL of their jewelry from MDC. I will continue to shop with MDC. David and Rosa are great and extremely patient. MDC's prices are unbeatable. There are not enough positive words to say about my experience with MDC or my ring. I have waited along time to have such a ring and thanks to MDC, David and Rosa for making my dream come true. Thanks!

"Sisterly Advice on Diamonds-2 Brothers Down 1 to go...MDC Only Choice!"

A year and half ago one of my 4 brothers asked for help finding a diamond engagement ring for his girlfriend. I told him we should look on line as he is out of town and it would be much easier. I came across MDC Diamonds on line and found the selection and prices to be excellent. After sending several options within his price range I told him to take all of the details (cut, clarity, color and carat) to a local establishment to see if he could get that kind of diamond at that price. As I suspected he could not. We were a little reluctant to make such a large purchase on line but went ahead and did so. The diamond arrived and he took it for an appraisal based on the paperwork it came with. He was told it was exactly what it said and that he got a great deal. The people at MDC were so great to work with. They answered all the questions we had so quickly. The diamond ring was sized and shipped within 2 days. When he finally proposed she was delighted with the purchase. They married last July and just found out they are expecting their first child this summer.
Because our experience with MDC Diamonds was so positive I suggested to my other brother who lives in Colorado that when he was ready to pop the question not to go anywhere else. He called in October and enlisted my assistance in helping him find the perfect ring. I immediately went to David's website and began my search. He was planning a trip to my house that month and I wanted to have some options available for him. I found several and saved them all on my "Watched Items" on EBay. There was one in particular that reminded me of his girlfriend. It was a vintage style band with a beautiful center stone and side diamonds. My sister agreed and when he arrived we convinced him that this was the "perfect" ring for Carrie. Again, we needed to have it resized and it was done and mailed to Colorado within a few days. There were some tricky parts to this shipment as it couldn't arrive at his house because it was a surprise and he didn't want her to see it. So we worked with MDC on where to ship it. Several emails and phone calls with his staff we had the details worked out. The staff at MDC was so helpful that it made our transaction smooth. The ring arrived and we had to wait a month before he proposed. When he did it was a total shock but she loved her ring. John actually told her he couldn't take all the credit that his sisters picked it out. She said it was a great choice. She loves it. My sister and I will not actually get to see it until the wedding this June since they live so far away but we are anxiously awaiting that time.
I would highly recommend shopping with David Cohen and his staff anytime you are looking for any type of jewelry. The customer service, the quality of the merchandise and the price make it a fabulous choice for anyone. It has been a pleasure doing business with MDC. I have 1 brother left who is not married and you can bet when he is ready I will be getting a phone call for help. I know exactly where I will be going. I myself will be heading to NYC in a few months for work and I will be stopping in the shop to see about upgrading my own center stone.
Again, I can't tell you how satisfied everyone involved in both transactions has been. Thank you very much for your honesty, quality and commitment to your work. Happy Holidays!!!

"MDC Diamonds Earrings"

I sent David at MDC Diamonds a picture and specs of a pair of Diamond Earrings I liked for my wife's Christmas present from a competitor's site. He first improved the quality of the diamonds then he cut their price a lot.
I received the earrings the day he said I would.
Best of all they are beautiful! They really sparkle even in a shadow. I can't wait to see her face when she opens her present.
Thanks David!

"The Best Experience Ever"

I found this vendor on the Internet and decided to take the giant leap of purchasing an engagement ring from a complete stranger. Not only did they custom make one to my specifications, they went out of their way to help expedite the process. When the ring was missing one element of the design and the time frame was tight, they still made it right and gave me 20% off anything in the store which I used to order my new bride a gorgeous pair of earrings.
Service, gorgeous items and great value. I will definitely recommend and buy from the again.

"Awesome Ring, Unbeatable Price and Service!!!"

Buying jewelry online is a very scary thing. David of MDC Diamonds was an absolute pleasure to work with. The bridal set is absolutely gorgeous!!! The ring was everything I expected, and more. The Asscher cut diamonds are perfect in every way. We can't wait to get the matching earrings and necklace from him. I highly recommend MDC Diamonds. I know I will never shop elsewhere.

"A Ring To Die For!!"

I purchased a lovely Marquise cut diamond engagement ring that I had been looking at for a few weeks. I compared this ring to some others from local jewelry stores, and the price from MDC was better in every single case. Every step of this experience was fantastic! David and his staff at MDC Diamonds were so helpful. They kept me well informed every step of the way as far as what was going on and when I could expect to receive my ring. In fact, I received tracking info from David a full day before Google checkout sent me the same info! I highly recommend MDC for anyone who is looking for high quality diamond jewelry at extremely competitive prices.

"Awesome Ring, Unbeatable Price and Service!!!"

I purchased a ring through the MDC Diamonds EBay site. I felt pretty good about the transaction since the seller had so many sales and yet maintained a satisfaction rating of 100%. I was contacted immediately following the sale, thanked for my business and asked for a ring size. I later called up the phone number listed for their central office and requested that the ring be set up and shipped as soon as possible, which they did. I got the ring two days following the phone conversation and took my now fiancé to Florida for the weekend. I decided to propose at Disney following the fireworks. She loved the ring, and we immediately had to take about 50 pictures. I would just like to say thank you for such a great deal and for awesome personal service. I have already recommended your business to my roommate who is looking to purchase a ring and I will tell anyone that I know about what a superb operation you have. Thank you again.

"The Best Experience Ever"

order a 1.42 Carat Heart Shape Diamond Engagement Ring from MDC Diamonds. They where great to work with and paid attention to every little detail. Very easy to talk to and work with. The ring was size and shipped out just like they said it would be. It even came a day early than expected. It was absolutely amazing when it opened it up and seen it for the first time. It was every thing they said it would be and then sum. I would have never be able to fine a ring like that locally for the same price. Plus you couldn't ask for a better salesman. I felt very comfortable taking to him and knew right away that he was someone I could trust. Witch made the whole experience that much better. Thank you so much David and everyone at MDC Diamonds you did an amazing job. I Highly recommend you and look forward to using you more in the future.

"Amazing customer service, and amazing quality diamonds."

I was referred to MDC from my best friend of 20+ years. He recently got engaged and got his ring from MDC. David at MDC helped me find my perfect engagement ring. I wanted something custom and he worked with me to find the perfect combination. At first I went with a local jewelry retailer. I settled for a lower quality center stone just to meet my budget. When I found MDC, I was able to get a center stone worth THOUSANDS more for the SAME PRICE. David had the ring made and shipped out in just over a week!

I was skeptical of buying a ring online simply because of the amount of money that is involved. The ring exceeded my expectations.

"Very Professional!"

I purchased an engagement ring for my girlfriend. At first I was a little skeptical about buying such a high dollar item online. My experience with MDC Diamonds could not have been any better. I got exactly what I wanted in a timely manner. They were quick to respond any time I had a question.

"Thanks so much MDC Diamonds!"

I have worked with David Cohen and MDC Diamonds for over two years now. My husband bought my engagement ring off of their website back in 2005. We loved our experience so much, plus the ring was absolutely beautiful, we requested they make my wedding band, which was a custom made eternity ring. This year, I decided to reset my engagement ring and immediately contacted David. That same day, I received a response! Two weeks later, I had my ring! The customer service he provides is incomparable and even though some might think it's a little scary to order expensive jewelry online, I was lucky to find the MDC Diamond staff and trust them 1000%. I plan on continuing to purchase items from them because I know that they will do whatever it takes to ensure customer satisfaction! Thank you so much for everything!
