Long ago, pearls were considered important financial assets since natural pearls are so rare to find.  Most pearls sold today are cultured. To create a cultured pearl, a tiny bead is implanted into an oyster. Gradually, the oyster coats the bead in many layers of natural minerals and proteins. These layers are referred to as nacre (nay-ker.) It is the nacre that gives pearls their beautiful luster and color.

Most cultured pearls are produced in Japan. In the warmer waters of the South Pacific, larger oysters produce the South Sea cultured pearls and Tahitian black cultured pearls which are larger in size. Freshwater pearls are cultured in mussels mostly in China.


Pearls produce an intense, deep shine called luster. This effect is created when light reflects off the many layers of tiny calcium carbonate crystals that compose the pearl. This substance is called nacre. When selecting a Pearl, consider that the larger the pearl, the more nacre it has, so it will also exhibit even more luster. Compare a smaller Freshwater cultured pearl with a larger South Sea cultured pearl and the difference in the amount of nacre is obvious.  The difference in luster is clearly visible.

The general color of a pearl is also called the body color. Typical pearl colors are white, cream, yellow, pink, silver, or black.  A pearl can also have a hint of secondary color, or overtone, which is seen when light, reflects off the pearl surface. For example, a pearl strand may appear white, but when examined more closely, a pink overtone may become apparent.


When cared for properly, pearls can last a lifetime. The best way to care for pearls is to wear them often as the body’s natural oils keep pearls lustrous. However, it's important to keep them away from household chemicals including perfume, makeup and hairspray. Chemicals found in these common products can dull the luster of your pearls. It is recommended that you put your pearls on last when getting dressed and make them the first thing you take off when you come home. Before putting your pearls away, wipe them with a soft cloth and store them separately from other jewelry to avoid scratching their tender surfaces.
