Su questo libro:
Dal retro di copertina: Since publication of Volume II in 1976, the tempo for the search for gemstones in North America has greatly increased with demand and advanced technology. In this definitive and final volume, Sinkankas shares his continuing research, and updates the development of the older, well- establish gem deposits. New discoveries and key persons in mining are introduced along with a wealth of historical and technical detail.
There's exciting new information about: Montana sapphires; red beryl from Utah; pink and green tourmaline from California and Maine; strongly-banded agates from the Midwest; pearls; insect-bearing amber; new diamond finds, and the prospect of commercial production of diamonds in North America--and much more!
Enhanced by maps of localities; book and periodical references; full-color photos by world-class gem photographers, Erica and Harold Van Pelt, this authoritative treatment of North American gemstone exploration is a necessary reference tool for anyone involved in the fascinating world of gems.
