The Chemistry, Properties and Tests of Precious Stones
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 purposes or simple curiosity, this book is an informative guide for any interested person in the allure of precious stones, as relevant for the general public as it is in the jewelry world.
