Would you like an independent opinion on your diamond or gemstone? We can help you get a lab report. We only use the GIA Diamond Grading Report. GIA reports contain scientifically determined information on diamond shape, Clarity, Color, Cut, Carat weight, proportions and finish. It also identifies any known treatments. Other reports from other entities have since made their way into the marketplace, but GIA is recognized as the original and unrivaled source for accuracy and integrity in diamond grading.
