We went here and they exceeded our highest expectations! They were so personable and greeted us by name every time we met. We found the PERFECT diamond and setting and independent appraisal. We were so beyond pleased that we asked them to do a ring guard and they definitely will be doing more for us in the future. My husband was a skeptic going into this process and these gentlemen made a believer out of him! Thanks guys! One happy wife here! - Connie Marshall

Gil & Nic were so great to work with. I made last minute changes and they were more than accommodating. If you're still on the fence about going with them, jump the fence lol. You will not regret it!

Searched for months for the perfect ring. They had it. They made it so easy, even when I needed it for the engagement, just to bring it right back fro sizing and final clean and polish. They made everything simple and a pleasure. I am now a customer for life!

Working with Nick and Gil was a great experience. My husband and I had an extra diamond that we did not need, but weren't too sure how to sell. Nick and Gil offered us a consignment option and our diamond sold within a few months. We got a decent amount back! Highly recommend working with this business as they are straightforward and extremely professional!

Really enjoyed working with Gil to create our beautiful ring. We picked out the stone ourselves and created the design of the ring. It is everything I have ever hoped for and I feel honored to wear it! I will recommend this place for anyone who wants unique, well crafted jewelry! The ring was within budget, we were quoted a reasonable time estimate, and has great customer service backing it up. We will be back to work with them in the future

This company is a quality outfit. Dealt with Nick and what a super experience. He will work with you and understand your needs and what you are looking for and then he will find it!

We went to the Diamond Exchange to discuss a new diamond for one of my wife's rings. Our goal was only go evaluate this company as one possible source of this purchase. Once we met Gil and Nic we developed an immediate liking for the ethics and friendship exhibited by them. Gil spent close to an hour explaining the various options available to us, after which we decided to make a purchase of an excellent new diamond.

We were very impressed that no pressure was put on us to make this purchase. We recommend the Diamond Exchange to anyone wishing to purchase a diamond at a very reasonable price. You won't be disappointed.

THE BEST PLACE in Houston if you're looking for engagement rings. Gili and Nick are THE DREAM TEAM, they found the perfect diamond and helped my fiance design my ring and it is just pure perfection. I can't imagine if we hadn't gone to Gili, nowhere else is comparable. He found both of our wedding bands for us as well. We will be returning for all special pieces going forward.

I went to Diamond Exchange Houston to shop for engagement rings. I did my research online for different jewelry stores in Houston in my hunt for a great deal on diamonds and engagement rings. These guys had great reviews so I scheduled an appointment. I met with Gili and he was very fun to work with. He explained to me what the qualities of the diamonds were and how they affected the prices. They also had different settings available.

He took his time with me and made me feel real comfortable. Other places I went to could not compete with the prices or the service of Diamond Exchange Houston. I will also be back in the future to shop for wedding bands.

I was looking for a place to sell my diamond jewelry and engagement ring so I could use the money to upgrade to a bigger and better ring. Luckily, I found Diamond Exchange Houston because they buy and they also sell diamonds and rings. The allowed me to just exchange my old engagement ring and the jewelry I had for a very pretty halo engagement ring. I absolutely love my new ring. They guys that work there are very knowledgeable and friendly and made the process fun and easy. They also said they would clean my ring anytime I needed it for free. Couldn't be any happier.
