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.
“If you would have light and heat, why then are you not more in the sunshine? If you would have more of that grace which flows from Christ, why are you not more with Christ for it?”
–Isaac Ambrose, Looking Unto Jesus
