Women who like wearing jewelry usually love diamonds, gold, and silver. Other women prefer pearls.
Pearls are beautiful, hard gems that come in white, red, gray, blue, green, and black. They are typically spherical in shape, but there are those that form unevenly, i.e. baroque pearls. Perfectly round pearls are considered the most beautiful and they are ideal to be used as jewelry.
Oysters produce these precious, iridescent stones. Amazingly, they are the by-product of a biological process that occurs when an irritant or a foreign substance such as a food particle, enters an oyster’s shell. Contrary to popular belief, the irritant is hardly ever a grain of sand.
Clams and mussels can also produce this precious stone, but not as frequent as oysters do. Imagine then this woman’s surprise when she opened a giant clam and found not just one pearl inside, but perhaps more than a dozen! What a very lucky girl indeed.
