her precious
stones, as well as of the beautiful semi-precious stones. Just enough of
the technical has been provided to make the new gem book a _vade mecum_
for students of gem minerals and for the army of jewelers in the United
States, as well as their fellow-craftsmen and merchants in all
English-speaking places. The art and industry of mounting gems is
somewhat elaborately covered, especially as exemplified in the work of
students at technical schools and the many unattached workers in jewelry
designing and making who form a part of the Arts and Crafts movement.
Some of the quaint superstitions about gems in the chapter on folklore
have a curious interest. The author takes cognizance of the public
desire nowadays for the novel and uncommon in gems, and shows that
prospectors, gem miners, mineralogists, and jewelers are co-operating to
greatly lengthen the lists of popular semi-precious stones. A chapter is
devoted to collections of gems in museums.
