I can’t say enough good things about this place! I worked with Sergio to design my engagement ring. He was so amazing, was willing to work with me to stay in my price range, and kept me updated every step of the way. I had such a great experience that my fiancé and I are using him to create our wedding bands as well. Highly highly recommend!

The transaction was smooth, easy and pleasurable. Kiefer helped with the entire process and was very communicative and even went above and beyond. Truly a stand up guy! Thank you JFJ for an amazing experience!

My fiancé and I worked with Jay on my engagement ring and we really had the best experience. Jay is so helpful, knowledgeable and trustworthy to work with that I feel comfortable enough texting him about all my jewelry needs. I cannot recommend him enough to all of my friends! They really do great work, cater to your needs, give great recommendations and overall just amazing service! Love this place!!!

I had the pleasure of working with Keifer Nuncio on designing a custom engagement ring. I was blessed to work with such a honest and creative jeweler. He took me step by step on how to pick the perfect diamond and not only did he have a great vision for what I wanted, he kept me well under my budget. I knew I had the best person for the job when he told me, "If you're going to spend big money, make sure it LOOKS like you did rather than just buying an expensive small diamond." Now that's realness at its finest. He looked out for me and my pockets with the bonus of me walking away with a high quality

I very much enjoyed buying two Rolexes from Kiefer. He was extremely easy to work with and genuinely cared about providing outstanding service. I am very happy with my purchases and was able to find a very rare Sky Dweller at a fair price.

My experience selling my watch with Sergio was fantastic. Contacted multiple dealers around Texas but Jonathan's gave me the best offer. Everything went very smooth with the transaction. I would highly recommend using Jonathan's for all your watch and jewelry needs! Wonderful small business to work with.

This review is long overdue! I found Jay through my family, and I'm so glad I did! He first made my engagement ring which I loved so much that I had him make my wedding band and even my first anniversary band. I checked out several local retail jewelry shops and was so unimpressed I wanted to give up. The quality and cost was outrageous and then I found Jay. His craftsmanship is impeccable and diamond quality is much better than any other I have seen. I highly recommend Jay at JFJ. You won't be disappointed! See attached photo.

I bought my wife a diamond wedding ring from Sergio 6 years ago which she absolutely loved. My wife and I are going through a rough time. She has been emotionally stressed. Yesterday evening she went to sell the ring to Kiefer. This morning she realized what a huge mistake she made and called Kiefer first thing in the morning. She explained that she made a mistake and asked what she could do to get her wedding ring back. At first Kiefer said the ring was gone. Later after checking he said it was in the safe. Sergio contacted my wife and instructed us both to come in and said we could work it out

I can’t express enough about the type of person Sergio is. From day one, Sergio was VERY Honest and more than Helpful. After shopping many jewelers I found that my experience with Sergio was like no other. He was very trustworthy and had everything I was looking for. He ensured me he would not let me down and proceeded to go above and beyond by guiding me throughout the entire buying and designing process. I found the perfect stone from Sergio and am HIGHLY satisfied with my purchase. I have found a lifelong jeweler that my family and I will always shop with. I highly recommend Johnathon’s

Where do I even begin... i am going to be brief and short. Basically, these guys have a very selective customer service. For me, it was basically, calling back over and over, and the guy kept on telling me he was busy with a customer. Well, I am a customer too! I guess they didn't want my business. No problem, there so many other places to go to.

They were polite, prompt, and most importantly provided the highest offer for my gold out of about eight places I checked, seven of which were in this same building. It was really a huge waste of time going to the other places who offered over 5% less and many of them wouldn't offer anything at all and said they just weren't interested in gold or "that type of gold". Unfortunately, Jonathan's only pays by check and they also want a fingerprint scan. The check is a little inconvenient and the fingerprint scan seems a bit intrusive and I didn't feel comfortable providing

My sister and I contacted Sergio when we decided to liquidate some inherited jewelry. Prior to meeting with him we had the jewelry appraised and his offers were all on par with the appraised values. He and the rest of the team were an absolute pleasure to work with and we will certainly go back if we decide to liquidate more or are in need of custom jewelry design.

Easy to work with Jonathan and his team to create the wedding band I wanted. The computer-generated images he was able to send me helped me design it even from a far away city. I really appreciated how easy it was to connect with him and his team to give feedback and make changes throughout the process. Amazing service, and I love my ring!!!!

My husband had my engagement ring modeled after a Tiffany one I loved, but we definitely couldn't afford. He said Sergio was amazing through the whole design process! I couldn't be any happier with my ring. We also got my wedding band from there to match. My mother's wedding set was also designed by Sergio. And once you get your rings cleaned after some wear, they look even more amazing! Love Jonathan's!!!

My engagement ring was truly my prized possession. Sadly, after my divorce, it had to go. I had a very positive experience selling it at Jonathan's; the transaction was quick and simple. I feel I got a fair deal and wouldn't hesitant to do business with them again if the opportunity arises in the future.

My mother had bought me this rose gold bracelet from Tiffany and from day one I have been unable to wear it as every time I put it on, it would fall off my wrist from a broken link. I had sent it back to Tiffany numerous times and every time I would get it back it would fall off again within a day. Searching for an outside source, I sent my bracelet Jay at Jonathan's Fine Jewelers, hoping to finally get a fix so I could wear my very overpriced Tiffany bracelet and voila! Jay was very professional and went over my options with me for fixing my bracelet and I can finally wear it! 2 years later

Update-Among other items, I had brought in 6 rings to sell the day I reviewed above, and the small guy with an office near the front door offered me $10 for them saying he was certain the were stones costume jewelry and settings not made of real gold. I was surprised at this as my mother never had any costume jewelry, but thought maybe she was mistaken and wasn't aware it wasn't real. Of course I declined his paltry offer. A few weeks later I went for a second opinion, and I took them somewhere else. I had them appraised, and sold TWO of them for $450, deciding to keep the others for

My fiancé and I designed our engagement ring together and found Jonathan's on a recommendation from my future father-in-law. Keifer, the young man we worked with, was very personable and communicative. While he was the person we worked with the most, everyone was very friendly and always greeted us whenever we walked in.

The whole process took about six weeks or so. We came with an inherited diamond from my mother. From the certification process to finding the side stones, Keifer kept us up to date and informed. He was even in good humor when it came to my long emails with lots of

I came in to sell some old jewelry...not knowing what the process was like or really what would be a good deal for what I had. I was ushered straight into the big boss' office, who was on the phone but still greeted me with a smile and started to look at what I had. He apologized after hanging up and took his time looking at the jewelry. He was very casual and laid-back, but I felt like he was really paying attention to what I had. He gave me a fair offer on the jewelry and even rounded the price up to a full dollar amount. Everyone else in the store was friendly and polite. I would highly

From the very beginning with the engagement ring to the custom designed wedding band, my experience here was amazing. It all started a little under 2 years ago, my now husband knew which diamond cut I wanted but didn't know what kind of band, so Jonathan had it set in a solitaire setting so that he could propose with an actual ring. The plan was to go back to design a custom band that I liked after I said, yes. I was never a solitaire ring girl, so when I opened the box, I was like "????? you got the diamond right, but a solitaire ring you know I don't like those!?!?!" Yeah

My husband and I did a lot of shopping around for a diamond before we visited Jonathan's. The prices here were anywhere from $2,000 to $7,000 thousand dollars cheaper than regular jewelry stores and slightly less than internet wholesale prices. The only thing I didn't care for was the craftsmanship of the setting they did. But by all means come here to buy the diamond and only after you have shopped around because this will the final place you go and I want you to know how much of a good deal you are getting.
