have a soft attractiveness that is in contrast with the flashing angles of the
majority of precious stones. They are usually cut en cabochon/sometimes turned
in the form of balls, and, as the stone is reputed to be potent in providing
good fortune;. Held in the mouth stimulates the memory. Would cure epilepsy
(French Basque province). During 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
porphyritic rock. Ceylon moonstone is sometimes erroneously termed "Ceylon
opal".
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.
