An Asian myth declares the best Blue Moonstones are washed up by the tides once every 21 years. The Romans believed the much-treasured Moonstone enclosed the image of Diana, the Moon Goddess, who could endow love, wealth, victory and wisdom upon the possessor. Other legends declared it contained the gifts of prophecy and second sight, claiming Moonstone could clear the mind and allow the wearer to reach wise decisions, and keep heart and mind in touch with each other.
Moonstones have been known to lose their silvery luster if their owners continued to hold within themselves a lot of anger.
In ancient lore, Moonstone was considered to be a talismanic gem of winter, and in Oriental culture was known as a “phenomenal gem” to be worn on Mondays. Phenomenal gems exhibited a moving line, star, or changes on the surface as the light varied, and was considered to bring good fortune to the wearer.
In observance of wedding anniversaries, Moonstones were considered the gift of choice on the thirteenth year. For this number, and for succeeding multiples of thirteen, the gem was believed to counteract the evil influence of the number.
Moonstone is the object of special veneration in history as a sacred stone of India. According to earliest traditions, the stone had been set, from the beginning of time, in the forehead of the four-handed god of the moon. Partly from its color, and partly from the influence of the deity it represented, it grew and lessened in luster simultaneously with the waxing and waning of the moon, gaining it the name it still bears, “The Moon-Stone.”
As a sacred stone in India, Moonstone is believed to bring good fortune and is never displayed for sale there except on a yellow cloth, as yellow is an especially sacred color. It has a special significance for lovers, believed to arouse tender passion, and allowing them the power to read the future, good or ill, that is in store for them. However, to gain this knowledge, the stone must be placed in their mouths while the moon is full.
