From the booklet’s abstract: “ Many semiprecious, but not precious, have been found in the United States. Beauty, durability and rarity are the most important qualities of of a precious gem. Gem stones are distinguished by their physical properties; color, crystal form, cleavage, parting, hardness, specific gravity, luster, index of refraction, transparency, and dispersion. Gems are named for their color, type locality, outstanding physical properties, and persons. The most popular gem stone cuts are the cabochon, rose, brilliant, step, and mixed. The carat, one-fifth of a gram or 200 milligrams, is the unit of weight measurement. The color of four popular gems may be changed by heat treatment or dyeing. Only the ruby, sapphire, spinel, emerald, rutile, and quartz of gem quality have been synthesized. The best quality of assembled stones are the doublet and triplet. Most gem stones are found in alluvial gravels and igneous rocks, especially granite and pegmatite deposits.” Booklet’s been stored in a smoke free home with two short haired pets.
