Largest Selection of GIA-Certified Diamonds

Diamond Factory Dallas has the largest collection of Certified Round and Certified Fancy Shape Diamonds in Dallas! Why? Because we actually have our own on-site Diamond Cutting Factory, which allows us to cut and polish our Diamonds, send them for certification, and then immediately make them available to You. Since we control the entire process, from Rough to Polished Diamond, we can ensure all of our Diamonds meet our strict quality standards.

Once our Diamonds are cut, they are then sent to The Gemological Institute of America (GIA), the leading authority on Diamond Grading. Here, they will be carefully analyzed and graded by trained Diamond Graders using an unbiased internationally recognized system. Upon grading completion, each stone will be issued a GIA Report which will state all of the Diamond’s characteristics.

When you purchase a GIA-Certified Diamond from Diamond Factory Dallas you will work with a member of our personal concierge team who will be available for any questions and to guide you through the entire process. We will help you with all aspects from selecting your Diamond to designing your setting. Should you want to upgrade your Certified Diamond in the future, you can always take advantage of our 110% trade-in program! Learn more
