Client Reviews

  • A hand wearing a large oval-shaped blue gemstone ring surrounded by smaller clear stones on a gold band, with a smartphone and a paper on a gray surface in the background.

    ⭐⭐⭐⭐⭐

    “J Patch Designs is owned by the most wonderful kind and genuine people such as Cliff and Karen. Other places turned down my request of improving my engagement ring, stating what I asked for was impossible... but J Patch Designs were able to do exactly what I wanted and more. Spectacular service online and in person, amazing fair prices, and I have been brought to tears with the beautiful work they have done for me and my partner. I will most definitely be entrusting more of my jewelry with them.”

  • Close-up of a hand showcasing a diamond engagement ring with a halo setting, worn on the ring finger, at an airport or similar setting with a glimpse of sneakers and luggage in the background.

    ⭐⭐⭐⭐⭐

    “I needed to get my engagement ring resized as it became too tight. I saw the great reviews for J Patch designs and reached out via yelp to get a quote and I quickly got a response. Karen was super knowledgeable and helped me pick the right size to go up to and was really detailed oriented in making sure she had all the details on the diamond on my ring. The repairs only took a short few days and the rings turned out great. It got a repolish too so now it's super shiny and the fit is much more comfortable than what I went into the shop with. Pleased with the service and would definitely recommend if you need jewelry repair work done.”

    ⭐⭐⭐⭐⭐

    “I visited J Patch to shorten a diamond tennis bracelet. Cliff was very kind and helped me choose a ring to make with the leftover diamonds removed the bracelet. They were incredibly fast, and the shortened bracelet and new ring both look fantastic!”

    Julie N.

    Durham, NC

  • Close-up of a hand with a large, ornate diamond ring on the ring finger.

    ⭐⭐⭐⭐⭐

    “I cannot recommend Karen and Cliff more highly. I wish I could give them 10 stars. Their integrity is unmatched. Karen and Cliff advise you like you're a close friend and not just a customer- even if it means that they won't make as much of a profit.

    My husband and I have countless pieces from them and are so impressed by the quality. We even had them reset my engagement ring that was from another jeweler, when stones continued to fall out of it.

    I wouldn't even consider going to another jeweler. Karen and Cliff are wonderful, trustworthy, kind and make stunning pieces that are built to become family heirlooms.”
