Kay was absolutely incredible & helped me find the most beautiful ring for my fiancé! She had a very good sense of humor & was able to keep me & the family entertained while I shopped for the perfect ring. She was able to find a ring for my fiancé on very short notice, I had about a month before it was to time. The ring sparkles in any environment & made for the perfect addition to proposing to my fiancé at the top of the lighthouse. Kay was very patient waiting for me go get the review done as well, knowing I had a few weeks before I proposed & needed to keep a secret. Absolutely will be back for future needs & encourage anyone looking to stop in!

Mrs. Kay helped me and my fiancée find my ring for our wedding in a very short timeline. Extremely helpful and a wonderful/sweet woman that I will visit every time I’m in the area and need to clean my ring. Never knew the process would be easy until we met Mrs. Kay and she walked us through everything!

My original wedding band was damaged beyond repair in an accident. Joe and Kaye at Mid Rivers Mall were determined to find a replacement ring, identical to my original wedding band. They succeeded, and we're so happy. They are a pleasure to talk with, and very helpful. Thank you for your persistence, and your kindness!
