This is the first comprehensive gemstone grading manual. The book divides into two parts. Section I describes the criteria used to quality grade faceted gems, cabochons, pearls, opals, star stones and Catseyes. Section II applies the grading criteria to 35 of today's most important gemstones. The book covers diamond, ruby, sapphire, emerald, tourmaline, garnet, pearl, agate and opal. The book includes 1st person travelogues from Mr. Wise's trips to the major gem bearing areas of the world, including Africa, Asia, Australia and South America.
