This online version of "Gemstones: An Overview of Production Specific U.S. Gemstones" contains the text of the originally published book in its entirety. Some figures, however, have been changed for purposes of online presentation. This publication was repurposed for online presentation by Andrea Greenwood.
The original "Gemstones: An Overview of Production Specific U.S. Gemstones" was published by the Gemstone Specialist of the former U.S. Bureau of Mines. Continuation of that service is now provided by the Gemstone Specialist within the Minerals Information Team of the U.S. Geological Survey.
As the Nation's principal conservation agency, the Department of the Interior has responsibility for
most of our nationally owned public lands and natural resources. This includes fostering the wisest
use of our land and water resources, protecting our fish and wildlife, preserving the environmental
and cultural values of our national parks and historical places, and providing for the enjoyment of
life through outdoor recreation. The Department assesses our energy and mineral resources and
works to assure that their development is in the best interests of all our people. The Department
also has a major responsibility for American Indian reservation communities and for people who
live in Island Territories under U.S. administration.
