Mary and the people at the Diamond Cellar did a fantastic job! From the start Mary made my fiance and I feel comfortable and welcome while we designed an engagement ring. The ring we wanted had small leaves on the top with a braid down the band, and Mary walked us through the process, explained how some ideas might not be structurally sound long term and helped us find alternatives that worked for us, helping us make a ring that was perfect. They even sent us a link to a 3d model that we could look at online and then were able to print a wax replica so my fiance could try the ring on to check fit and size. The whole process was easy and straightforward, and the price was very reasonable. Having never done something like this before, what I thought might be extremely complicated and might break the bank turned into a fun experience. If/when we do something like this again we will definitely come back.

I had an outstanding experience at Diamond Cellar purchasing my first Rolex to celebrate the birth of my daughter. Jim made the process fun and got me my top pick way faster than other authorized dealers. We enjoyed the space and experience. The entire team was friendly, helpful, and welcoming each time we visited, and my wife enjoyed exploring their beautiful jewelry selection. As promised, Jim even made it into the baby book. A truly memorable and five star experience all around.

I cannot say enough amazing things about my experience with Dawn at Diamond Cellar. From start to finish, the process of designing my engagement ring was seamless, thoughtful, and truly special. They took the time to listen to exactly what we wanted, answered every question with patience, and offered expert guidance without being pushy. Their attention to detail, craftsmanship, and genuine care made me feel completely confident every step of the way. Aside from the ring what really stood out was their level of professionalism, honesty, and personal attention. We never felt like “just another customer”. I am so grateful for the experience and would highly recommend them to anyone without hesitation!

Alex and team are absolutely incredible to work with. First class experience all around. We trust them wholeheartedly with all of our Rolex, David Yurman, Patek Phillipe purchases. Their store is tastefully done, Molly and Alex’s staff are second to none. I highly recommend them for any jewelry purchase. Especially if you wish to build a relationship with a local family owned jeweler.

Dawn was extremely knowledgeable and cared about our purchase. She was professional and a wonderful representative of DC! Jewelry master, Jeff, also deserves a heart felt thanks. He made time to set our new ring even though it was extremely busy!! Thank you, Jeff and thank you, Dawn for making our purchase everything we wanted it to be.
