Natural Mother-of-Pearl Shell

Meaning and Properties

History


Mother-of-pearl shell for jewelry refers to the nacre that coats the inside layer of the mollusk shell which is used to form pearls--hence, it's the mother of the pearl. Mother-of-pearl shell jewelry can include much larger focal pieces than simple pearls since nacre substance takes up a whole shell's interior, offering a larger working surface for carving. In addition to jewelry, mother-of-pearl shell has been used in medieval European, East Asian and Islamic religious art. Starting during the Victorian Era, mother-of-pearl shell began to also be used for clock faces, buttons, jewelry boxes and more. One especially popular use was inlay work, such as the handles of knives and pistols, as well as historical and contemporary use as inlays for guitars and other musical instruments.


Mother-of-pearl shell jewelry is considered organic jewelry, yet not always renewable. Therefore, environmental concerns have led to some designers using only vintage mother-of-pearl shell or selecting shell rough by the ecological stability of the pearl or seafood farm from which it came.

Metaphysical Properties


Natural mother-of-pearl shell has tremendous spiritual value for those whose high goals and attitudes keep them feeling stressed. Mother-of-pearl shell is commonly believed to attract prosperity and is often used in mystical work and lore to heighten intuition, psychic sensitivity and imagination. It is believed that mother-of-pearl shell offers soothing, motherly protection from negative energy and love. Due to this, mother-of-pearl shell is a recommended crystal healing gemstone for children.


Mother-of-pearl shell turns on the Solar Plexus Chakra as well as the Throat Chakra.


Geological Properties


Natural mother-of-pearl shell is found all over the world and is more common than pearl. This is because the mollusks that produce pearls will always have a shell, but will very rarely contain a pearl. Found in saltwater and freshwater varieties, mother-of-pearl shell sources include Australia, Burma (Myanmar), Central America, China, Europe, French Polynesia, Japan, the Gulf of Manaar (between India and Sri Lanka), Madagascar, North America, the Persian Gulf, the Philippines, the South Pacific Islands, South America and Southeast Asia.

Designing with Natural Mother-of-Pearl Shell
