Your Top Source for Diamond Expertise

Educating diamond buyers since 1985

Diamond Cutters International (DCI) has been involved in educating diamond buyers since 1985. In 1991 owner Fred Cuellar, also known as The Diamond Guy, penned the best seller, “How to Buy a Diamond” and became the diamond expert for a variety of publications and organizations including Men’s Health Magazine, America Online, The Weddingpages, and MSNBC. In 1998 DCI developed the National Diamond Helpline, dispensing free advice and appraisals on a toll free number.
DCI is one of America’s few diamond houses open to the public by appointment only. To get an idea for the level of quality and craftsmanship you can expect from DCI, visit our Design Portfolio and Championship Rings gallery for samples of our work.
As a Testament to the quality of service offered by Fred and DCI many people have written to Fred to thank him. Read some of these stories in our Testimonials Section.
