Topaz. A mineral occurring in rhombic prisms, generally yellowish and pellucid, also colorless, and of greenish, bluish, or brownish shades. It sometimes occurs massive and opaque. It is fluosilicate of aluminum, and is used as a gem. It is but little more valuable than the garnet, except occasionally unusual fine specimens.
“Where the grace and love of God is shed into the soul, all will follow.”
