the waxing of the moon it was an efficacious love charm; while during the
moon's
waning
it would enable its wearer to foretell future events. If there is any basis in fact for this belief, it
should be the favourite gem of tipsters of the race tracks and stock market. A
sort of cousin-german of the moonstone
is
the sunstone (a transparent variety of calcite or crystallized calcium carbonate),
which however is a far less important luminary in the firmament of gems. The
true moonstone is the opalescent variety of orthoclase-feldspat
(=
adularia). Albite occurs in opaque to transparent masses and in triclinic
crystals having a dual cleavage in different directions.

in pieces several inches in diameter resulting from the decomposition of a

The
term sunstone, or heliolite, is applied to aventurine kinds of oglioclase, one
of the feldspars; these are of a greyish white to reddish gray colour with
internal yellowish or reddish reflections, proceeding from
disseminated
crystals or flakes of iron oxide. Sunstone is found at Lyme, Connecticut, among
other American localities. Its use in jewelry is now very limited; it is not
costly, and artificial "sunstone" or "goldstone,"
made
of glass, containing sparkling particles of metal, is often preferred to the
genuine.
