About Cook Diamonds

COOK DIAMONDS is the perfect example of a family jewelry store business success story in Dallas, Texas. Colleen began working in the jewelry industry in 1974 as an assistant to a local diamond importer. After two years, Colleen decided she liked the business well enough to strike out on her own by offering engagement rings, fine jewelry and loose diamonds.

COOK DIAMONDS has the distinction of designing and creating two of the Dallas Cowboys Super Bowl rings. The Dallas Cowboys’ Super Bowl XXVII ring was the largest, most valuable and unique ring in sports history. Designed and created by Balfour and COOK DIAMONDS, the centerpiece of this year’s championship ring was a dazzling five-point Star shape diamond. COOK DIAMONDS represented the only cutter in the world to have perfected the art of laser technology and hand faceting a diamond into the shape of a symmetrical star without sacrificing the stone’s natural brilliance and clarity. Each handcrafted ring was the end result of 200 painstaking steps and was subjected to strict quality control measures to ensure its status as a valuable collector’s item.

For the Super Bowl XXVIII ring, COOK DIAMONDS was again selected as the diamond supplier. The Cowboys chose a design that was centered around four Marquise diamonds to commemorate their fourth Super Bowl victory.

When asked what was the secret of their success, Colleen said that it was the ability to deliver the highest quality jewelry pieces and diamonds available, accompanied by personal service at an affordable price. Colleen added, “We want the people who come in to our Dallas jewelry store to remember who we are and the personal service they received. In short, we want them to come back.” Colleen elaborated on another of COOK’S distinguishing features, explaining “We feel it is important for our customers to understand exactly what they are buying, the fine craftsmanship of a watch, engagement ring, a piece of custom jewelry, or the unique characteristics of a precious gemstone.”

COOK DIAMONDS also believes in giving back to the community that has helped make them successful. They are contributors to many local charitable fundraising activities in Dallas, Texas.

Professionally, COOK DIAMONDS is a member of the Jewelers Board of Trade, the Jewelers Vigilance Committee, and the Better Business Bureau, and is a supporter of the Gemological Institute of America.
