I have been going to Diamond Castle for the past 25 years. My husband and I bought our wedding rings there in 1996 and have continued to visit them for our jewelry purchases. Just last week, I took my son in to pick out a gold chain. The owner of the store was extremely helpful, professional and didn't try to "oversell" us. If you are in the market for a wedding/engagement ring, or a special gift, I highly recommend visiting Diamond Castle. You won't be disappointed.

Kevin was an absolute pleasure to help guide me through the engagement ring process. I visited other jewelers before I came to Kevin and he and his team set the bar way high. He not only helped me find the perfect ring, but educated me on diamonds which was extremely helpful. I recommend Diamond Castle every time for your jewelry needs.

Best purchasing experience I've ever had. Kevin and the staff made me feel welcomed from the get go. They made a normally stressful and difficult life decision (buying an engagement ring) into an easy, straight forward purchase. He was honest and guiding and I will be using diamond castle for all my future jewelry needs. 10/10

We recently worked with Kevin on customizing a new engagement ring. It is beautiful and exceeded all expectations! Kevin was incredible to work with and was very accessible throughout the process. He delivered with his promise to have the ring completed by a certain date which was amazing. We highly recommend using Kevin and his business!

I could not be happier with my experience with Diamond Castle Jewelers! They came highly recommended from my close friends and so I went there. I worked with Kevin and his father to purchase the perfect wedding ring, as well as build a custom necklace. They were tremendously kind, are unparalleled experts, and have a genuine passion and love for both gemology and customer service! There is no greater compliment I can give an establishment then this: I will be referring all family and friends here for all jewelry purchases and will be returning myself for future purchases. Thank you for everything!
