21st Century Certificate for $21: Actual data from ImaGem's GL3100

ImaGem conducted a study to assess the accuracy, precision and repeatability of its technology. 10 diamonds were randomly selected with GIA Certification. Each diamond was run three times. Please note that instead of running a diamond consecutively, a random table was used to determine the order in which the diamonds were run. This approach meets the scientific requirement for collecting and evaluating performance data of a system. The results obtained from the study are given below. Detailed data are available upon request.
