The brilliancescope was looked at by two major laboratories, the American Gem Society and the Gemological Institute of America. Both of them found the machine to not work sufficiently to be included in the tools that they were using in their studies of diamonds and how they were affected by cutting.

Among the problems were a lack of consistency and repeatability and the fact that diamonds could be cut to perform well on the machine, when other diamonds that had equal or superior light performance did not perform as well on the machine. For this reason we have chosen not to include it in our extensive tool kit.
