GEM HUNTER'S GUIDE by Russell P. MacFall


Email this review


A clear, concise round-up of information for the amateur gem hunter in particular, this gives the elements of identification of gem stones, the requirements for the hunt, describes gem minerals as they really look and shows them in their natural state and after setting. It lists the characteristics of important gem stone materials from agate to zoisite, discusses the use of black light for fluorescent minerals and lists their color and wave length of response and site. There is a note on judging the quality and value of the stones (some nine tenths of which among amateur unters are of the quartz family), on diamonds and pearls in the United States, on collectors and collections. The main section of the book is devoted to a directory and detail maps based on highway maps of gem hunting locations in the United States, anada and Mexico. A glossary, sources of information, and suggestions for further reading complete a very useful handbook. This is a revised, expanded third edition of an out-of-print original.
