  • Elizabeth at Diamond Designs is FANTASTIC! I wanted to update my wedding band and ended up with two. I was so pleased with the new look of my ring that I went back and had her help me create a memory ring. I had a vision in my head, and she NAILED it. This locally owned jewelry store sure makes you feel like part of the family.

  • I got the most beautiful engagement ring here and I couldn't be happier! Everything from the beginning to end of the process was as smooth as possible and the end result is better than I could've imagined! The owner is running a wonderful business here.

  • My dad gave me my mom’s wedding ring set after she passed away that he had bought at a store that had been out of business for years. We took it in to the ladies at Diamond Design to get sized to fit me and they did a great job. My ring size was 6 sizes larger than my mom’s so it was a difficult job for them to but they did a great job and in a short amount of time. I will absolutely recommend them to anyone looking for a jeweler.

  • Absolutely love Diamond Designs by the McNeills! My most recent visit was to have my wedding rings soldered together. They had a few questions for me regarding the look of how my rings would turn out and offered to FaceTime me! Game changer!!!!! I was able to clarify specifics on my rings without driving back into town. As a momma of three, I appreciated this SO much! Love this business and will continue to go there for all of my jewelry needs.

  • Excellent job of soldering my two wedding rings together and excellent job of rhodium plating my rings. A few years ago the jeweler put my former engagement diamond into a new setting and even though the diamond was a bit odd shaped, the jeweler met the challenge and I still love it.
