I could not speak more highly of Darren. He was very insightful and helpful as I selected and purchased my Fiancé's wedding ring. He made the entire process easy, fun, and insightful. I would recommend Carbon Diamonds to my family and friends in a heart beat!

When my now husband and I were shopping for an engagement ring we searched at all the usual higher end shops. I wanted something different and not cookie cutter which is hard to find. We heard about Darren and decided to meet with him to discuss our wants. From the first appointment we knew he was the guy!

Darren is a wonderful person, and incredible to work with. He helped me with finding the perfect engagement ring for my fiancé all the while educating me about diamonds as well as the diamond industry. His transparency about how everything works was incredibly refreshing, and I would highly recommend Carbon Diamonds to friends and family.

I normally don’t do the review thing but the customer service was everything you dream of when having something custom made. Darren and Tanner did a great job on my wife’s custom dream ring! Not only did they educate us on the different qualities and shapes of diamonds they also taught us about the 4 C’s! I’m referring these guys to all my friends! Thank y’all for helping us make our dreams come true!
