"This celebrated encyclopedic work, by far the most thorough and complete up to date, easily surpasses Bacci, Marbod, and Leonardus in quantity and quality of information; it is further distinguished by its intimate knowledge of the art of the lapidary and must therefore be regarded as the first treatise to offer more than the briefest of views of gem cutting"--Sinkankas 778.
