first edition of the first systematic mathematical analysis of the optics of diamonds. "Tolkowsky demonstrates light paths in rose-cut and brilliant-cut gems, and shows how only certain angles of facet inclination can insure production of maximum brilliance"--Sinkankas 6663. With little alteration, today's standards for "ideal cut" diamonds are based on Tolkowsky's book.
