Pearls have held a mysterious fascination for centuries, partly because for a long time it was not known how they formed. Many legends were created to explain these shimmering treasures. Pearls are crystallized raindrops swallowed by oysters. Pearls are drops of semen from Celestial Dragons that fly over the sea. Pearls are the foam from the lips of Water Dragons. According to science, pearls are formed when an oyster swallows a grain of sand or grit that irritates it. In order to soothe the irritation the oyster covers the offending piece of grit with many layers of Nacre, the same material that forms iridescent sea shells and Mother of Pearl.
The glowing whiteness of Pearls, as well as their association with the sea, has caused them to be classified as Lunar gems, under the rulership of the Moon. Pearls are used in spells to become more attuned to the lunar cycles, increase your psychic powers, become more skillful at scrying and divination or communicate with Naiads and other spirits of elemental Water. Pearls are used in charms or spells to heal the effects of conflict, ease trauma and break away from an aggressive or domineering person who has too much control over your life.
Freshwater Pearls which are naturally formed tend to be much more expensive that 'cultured Pearls' which are grown for the jewelry market. If possible, I'd recommend working with and wearing natural pearls. The process of creating cultured pearls is considered to be cruel by many people, though there is a great deal of argument about the ethics of the industry and whether oysters can be considered to experience suffering in the same way that higher mammals would in the same environment. Minute 'seed pearls' are inserted into live oysters and then Nature is allowed to take her course. Many oysters die during the seeding process and all of them die when the finished pearl is removed. Organic gems are believed to draw and store energy as effectively as any stone or crystal and many magic users do not feel comfortable working with the energy of cultured pearls.On the other hand, cultured pearls are much less expensive than freshwater pearls and can be bought in a range of beautiful, permanently dyed colors, making them popular with magic users who like to work with color energy.
