The
book of John Mastin works very thoroughly and takes up all the information
related to precious stones, be it for the practitioner or the enthusiast. This
manuscript works out the origin of gems in detail and lists their physical
properties-crystalline structure, color, hardness, and specific gravity. An
interesting add-on included in the book is the influence that magnetic and
electric fields will have on gemstones, explaining to the reader the particular
characteristic qualities of each gemstone. From this perspective, the cutting of
stones, imitations, and testing methods are analyzed. Whether for teaching
