Mother-of-pearl gemstone

other-of-Pearl or nacre (nā“kr) , is the iridescent substance that forms the lining of the shells of some fresh-water and some salt-water mollusks. Like the pearl, it is a secretion of the mantle, composed of alternate layers of calcium carbonate and conchiolin. Among the chief sources are the pearl oyster, found in warm and tropical seas, chiefly in Asia; freshwater pearl mussels, which live in many rivers of the United States

Reflecting the rainbows of the ocean beds, iridescent Mother-of-Pearl is the Opal of the sea. Like Amber, Mother-of-Pearl is organic, but unlike any other gemstone it forms locked away within its creator: the mollusk.

15th Century Europeans, during the reign of Queen Elizabeth I, gave Mother of Pearl its name. However the beauty of Mother of Pearl, associated birthstone of June, has been used in the decoration of precious jewels and ornaments as far back as 3000 years before the birth of Christ.

Mother-of-Pearl is a hydrated gemstone, so it is essential to keep it away from direct sunlight, strong sources of heat or very dry atmospheres. If Mother-of-Pearl is left to dry out its surfaces crack and it becomes less resistant to wear and tear. Never use strong abrasives or alcohol to polish your Mother-of-Pearl, as this will destroy its play of color.

Store your Mother-of-Pearl in a dark cool place, and keep it looking its best by wiping it occasionally with a damp cloth. Wear it often; Mother-of-Pearl loves the bodies' natural oils. The Nizams of India, famous for their pearl treasures, used to adorn their court eunuchs with pearls as their body oils kept the pearls in perfect condition!

The three most popular colors of Mother-Of-Pear in today's jewelry are white, black and pink.
