2012 Reprint of 1931 Edition. Exact facsimile of the original edition, not reproduced with Optical Recognition Software. This is the first formal treatise on amateur lapidary work published in the United States. In the U.S. there was little activity in the field of lapidary until the 1930s, when European craftsmen emigrated to New York to serve the jewelry industry.
