Cultured pearls VS natural pearls
A natural pearl begins its creation as a foreign object. A piece of sand gets lodged inside an oyster's inner body where it cannot be expelled. The oyster goes into defensive action and secrets a substance called nacre around the irritant to protect itself. For how ever long the irritant remains within the body the oyster will continue to secrete nacre around the irritant, adding layer upon layer.
The number of natural pearls is relatively small. Without cultured pearls, only the extreme wealthy would have the chance to own the treasured gems. Man-made pearls are produced in factories without the help of oysters but organic and inorganic compounds and chemicals. A popular technique includes taking a glass bead and dipping it in a fish-scale and lacquer substance. You can tell by pearl shine on the surface whether it is man-mad or cultured because artificial pearls shine on the surface like nail polish. Cultured pearls have an authentic looking glow that comes from the inside
It takes more than 800,000 oyster hours to grow cultured pearls considered of "high quality."
A pearl farmer has to sort through 10,000 pearls in order to gather 47 matched pearls that will make a high quality necklace. In an assembled strand all pearls must match in luster, shape, color, and size.
All Japanese cultured pearls have the nuclei shell beads come from freshwater mussels that are from the United States.
Presently, pearls are coming back into fashion, being worn with any type of clothing or style.
