CHRYSOLITE  , a transparent variety of

olivine, used as a gem-stone and often called peridot . The name chrysolite, meaning " golden stone " (xpuubs and Mos.), has been applied to various yellowish gems, notably to topaz, to some kinds of beryl and to chrysoberyl . The true chrysolite of the modern mineralogist is a magnesium silicate, referable to the species olivine . It is appropriate to call the lighter coloured stones inclining to yellow chrysolite, and the darker green stones peridot . Certain kinds of topaz, from the Schneckenstein in Saxony, are known as Saxon chrysolite; while moldavite, a substance much like a green obsidian, is sometimes called water chrysolite or pseudo-chrysolite .
