I enjoyed working with Gili on a custom ring. I came in with a vague idea and he was patient in giving advice and ultimately creating the design that I had in mind. He was upfront about pricing and timeline so that there were no surprises. If I need to get another diamond, I'll be back!

I purchased our original engagement ring from Nic years ago. I had some specifics I wanted, Nic listen to understand as opposed to listen to respond. I didn't feel like I was being sold to like all of the other places, he was giving me a real solution to a big decision. Fast forward years later when I decided to upgrade it was a no brainer to go see Nic. Seamless experience from start to finish. It's the hardest flex when I tell people I got a diamond guy. Thanks for the help Nic.

I am a very picky customer that was shopping for the perfect diamond for an engagement ring. I met with Gili and he was beyond patient with me until I found the perfect diamond. He showed me several diamonds that meet my criteria until I found the diamond that I wanted to use. The engagement ring came out perfect. I will continue buying from Diamond Exchange Houston for all of my diamond needs.

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!

We looked any many places to trust with the sell of our Diamond before deciding to give Diamond Exchange a try. Indeed we we were not sure how things would go, but the process is transparent and no stress. We got a great offer within a few days but it was not quite what we were asking for. The team put no pressure on us to sell. We waited a few weeks more, then got our full asking price - bam! Thx Nic and crew for all your help. I'd recommend them to get your sale done as well.

This place was a life savor. I spent weeks looking for a wedding ring and the minute I walked into Gili's office, I knew this was my final destination. He showed genuine interest and patience in making sure I picked the right ring. He was transparent with me the whole way through this experience and made me feel like I was actually making a good purchase. I HIGHLY recommend coming here for any and all jewelry. Thanks a million Gili!

After researching and seeing diamonds on Blue Nile, I wanted to see exactly what the diamonds looked like to match what I picked out on Blue Nile. So I called one day in March out of random to just possible come in to see what diamonds look like with NO intention to buy. Lol. Nic was able to get me in and situated that day without an appointment. He showed me everything I was looking for and MORE.

I was very much impressed by not only the pricing but also the detail he went to show me exactly how to verify diamonds and show a novice exactly what matters. In conclusion, I ended up purchasing an engagement ring that day! One month later, She said YES! And the ring is the talk of the town. Absolutely love the ring and the customer service from Diamonds Exchange. PLEASE VISIT THEM!

I'm so glad that my fiance found this place! Gili is super helpful, knowledgeable and responsive! His dog, Didi, is super cute too! We came on a Saturday afternoon to look at various natural stones but we didn't find what we were looking for initially. Gili informed us that he would have a wider selection to choose from the following weekend. He showed us a variety of natural stones and I found THE perfect one!

I had specific customizations that I wanted in the ring and it arrived well before the estimated delivery window. I'm super happy with the final product and can't stop staring at this new hardware of mine. I came back again this past weekend with my mom to look at stones for a pendant necklace! I'm super pleased with the customer service and advise everyone to purchase their diamonds through Diamond Exchange!

Stopped by on short notice with a last minute appointment but Nick and Gili still took their time helping me pick out the perfect engagement ring. I really appreciate these two guys and their hospitality during the entire process. Definitely will recommend to my friends and family for all their diamond needs.

Don't go diamond shopping in the mall! You will get way more quality and peace of mind for your money buying from Diamond Exchange. Gili is extremely experienced and knowledgeable as he grew up in the diamond industry. We told them what we were looking for in advance, so they had several diamonds available to choose from. We were very pleased with our diamond and the whole experience! Highly recommended!

After interviewing many jewelers, Gili made me feel the most comfortable. Gili is a true scholar and consummate professional in his trade, which made me feel well informed from start to finish. The selection of diamonds is endless, and he is very prompt to acquire anything that is not in stock, even extremely rare diamonds. I was looking online for a month trying to find a very unique, rare stone without any luck. Gili found it, and had it in his office for me to view in-person within 72 hours. Gili takes a proactive approach to business, and you can tell he truly enjoys helping others. The communication was excellent and I would highly, highly recommend doing business with Gili. I will be a repeat customer forever!

Highly Recommend DIAMOND EXCHANGE HOUSTON! Nick and Gili are great guys, extremely professional and provided a safe and secure environment for us to discuss how much they could potentially sell my wedding set for. The entire experience was stress and hassle free. They kept me updated every step of the way and sold my jewelry and got me paid in 2 weeks! Talk about great customer service!

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.

Thank you Gili and Nick for helping us pick the perfect engagement ring! Diamond Exchange Houston has the best quality diamonds on the market. Gili walked us through different cuts, carets, clarities and styles. My custom engagement ring was ready in about two weeks for pick up. We got a great quality diamond for a very reasonable price. GIA certification was given with the pick up of the ring. Diamond Exchange Houston has a large variety of many semi precious stones, metals and fine jewelry pieces. Custom made, and even vintage pieces. I will be doing all my future jewelry buying with them.

I want to thank Gili and Nic for helping me find the perfect engagement ring for my soon to be wife. I did shop at other jewelry stores in Houston but these guys had the best prices on loose diamonds and the custom engagement ring that they made me came out perfect. They even made time to meet with me on a Saturday when they were supposed to be closing. I will be coming back for wedding bands and I will refer my friends and family

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.
