Wow!! I’m blown away impressed with John’s work. I picked my wedding set up today after a stone falling out and I almost didn’t recognize them. They’re perfect and look brand new! I highly recommend using john for any repair work!

I went there today to get my engagement ring fixed, one of the prongs was bent and John was able to fix it right then and there! They didn’t charge me anything and they were very nice and their dog is absolutely adorable!! It was one of my favorite birthday present yet! Thank you!

Johns Jewelry did an awesome job switching up my engagement ring! I would 100% recommend him to anyone who wants fast and friendly service! Katie was very informative and knew all the different styles! Thank you for making my experience amazing.

Got my mom a necklace for her birthday. Both John and Katie were so nice and knowledgeable! I don’t think I’ll ever shop anywhere else for jewelry!
