Pearl - June birthday gemstone
Pearl is the birth stone for the month of June. It is also the accepted anniversary gemstone for the third and thirtieth years of marriage.
A pearl is the product of an oysters defense mechanism. When a foreign irritant is introduced either by man (cultured) or naturally, the oyster immediately surrounds it with layers of a substance called nacre. This forms the exquisite gemstone know as pearl.
Pearls come in a wide range of colors. They should be relatively free from skin blemishes. The more perfectly round the shape the better. The higher the lustre or 'orient,' the more valuable the specimen. The larger the pearl, the greater the value.
Besides the popular round shape, there are stylish mabe (large hemispherical cultured pearls), fresh water (elongated in interesting shapes and colors), and South Sea (large cultured pearls 10mm and up, from Australia's and Indonesia's waters), to name a few other variants.
Pearls have been recognized as the emblem of modesty, chastity and purity. They have come to symbolize a happy marriage.
Avoid household chemicals, cosmetics, hair sprays, and perfumes. Don use ultrasonic cleaners. Wash with mild soap and water and store in a protective chamois pouch or tissue paper.
Moonstone is sometimes used as an alternative by those born in June since it physically resembles some pearls.
