stone. When cut with a See also:convex See also:surface it displays a soft milky reflection, forming a luminous See also:band, but not sharply defined as in See also:cat's-See also:eye. The See also:ordinary moonstone is a translucent variety of See also:orthoclase known as adularia (see ORTnO0LASE), whence the See also:peculiar sheen has been called " adularescence." The effect is probably caused by interference from twin lamellae, or by numerous enclosures of microscopic laminae, definitely orientated, and it has been suggested that these may often be flakes of See also:kaolin due to incipient decomposition of the felspar. Practically all the moonstone of See also:commerce comes from. See also:Ceylon, principally from the Dumbara See also:district of the Central See also:Province. It occurs as pebbles and irregular masses in the See also:gem-gravels and See also:clay-deposits, and is also obtained by See also:quarrying an adularia leptynite, as described by Dr. A. K. Coomaraswamy. Very similar in some respects to moonstone is the chatoyant soda-felspar which was called by T. Sterry See also:Hunt peristerite, from Gr. ireptarepa, a See also:dove, in allusion to the resemblance of its lustre to that of the See also:bird's See also:neck. The See also:original peristerite was from See also:Bathurst, near See also:Perth, See also:Lanark See also:county, See also:Ontario, but it occurs also at See also:Macomb, St See also:- LAWRENCE
