Science Of Gems, Jewels, Coins And Medals (1875)

This volume discusses gems, jewels, coins and medals of ancient and modern times. At almost all times, gem engravers have cut devices on precious stones so that in fact, as jewels are gems, not all gems are jewels. They are treated the same in this work. Billings writes about the history of coins and medals, some of which are found in archeological sites. The appendix is a translation by Mrs. Billings of the Autobiography of Benedetto Pistrucci.
