Abstract
Apparatus for assisting in the qualitative evaluation of facted gems (i.e., gems having cut facets formed thereon), which magnifies the radiance of cut facets illuminated by colored light beams so as to allow direct viewing or the formation of a color image which can be expressed on a video screen and/or a video printer. The beauty of a gem at the time of its appraisal and sales is thereby increased by use of the apparatus which thereby contributes to gem appraisal and sales by arousing customer interest.
