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!

We recently purchased a wedding/anniversary set from Diamond Castle and we very happy. We worked with Kevin and he did a great job of guiding us through the process. We found him to be very responsive to our questions and he made sure to communicate with us during the process of designing our selection. It is the best feeling when you pick up your ring and it is exactly what you were hoping for!

If you're looking for a world-class jeweler with staff that treats you with the kindness and care of family, there is no better place than Diamond Castle. From start to finish, Diamond Castle provided a wonderful shopping experience. I was able to create a custom-designed wedding set without having to sacrifice quality of the diamonds or spend over my budget. Kevin and his staff truly went above and beyond to make me feel comfortable and help me find the perfect fit.

My new wedding set is more stunning than I could've ever dreamed up, and the quality of the craftsmanship is truly something to be admired. Thank you to the entire Diamond Castle Jewelers team for helping make my diamond dreams a reality!

I found this company online late at night for a quote and receive a return phone call the next day, less than a few hours later. I was able to go into their store to have my wedding rings resized. Kevin was very professional and knowledgeable about my needs. I highly recommend Diamond Castle Jewelers for all of your needs.
