For Rockhounds

New Zealand Gemstones. By Lyn and Ray Cooper. Reed. 125 pp. Illustrated. This book on the semiprecious gemstones to be found in New Zealand is a gem in itself and the evergrowing number of “rockhounds”—a name several generations have given to geologists and which is now used to describe those who collect and enthuse over rocks and gems—will welcome it. It was almost inevitable that such a book should appear, in view of the widespread interest in gemstones, but that it should be so comprehensive makes it doubly welcome and of great value to both the amateur (the rockpup) and the professional. The authors have provided maps showing the areas throughout the country where various types of stones can be found and have given in great detail methods of cutting, polishing and using the stones for such items as jewellery, lanterns or for pictorial effects. 1 While New Zealand Is fortunate to possess an extensive

variety of beautiful gemstones, the authors point out that only one stone among hundreds of thousands can be regarded as a “real winner." The authors also stress the care that must be taken in tumbling, or polishing, the stones. It is clear that this new craft, while appealing to many, has to be undertaken seriously if good results are to be achieved.
