A pearl is formed by an oyster and is made up of layer upon layer of a crystalline substance that is called nacre. The nacre is created by the oyster as a reaction to an irritant, such as a piece of sand, that is placed in the oyster's body by a qualified pearl expert.

Only natural pearls are formed by layers of nacre deposited around an irritant that occurs naturally (not placed by man) in the body of the oyster.

A pearl formed in any other way may resemble a natural pearl, but, having been man-made through a manufacturing technique, is an imitation or simulated pearl. A reputable jeweler will label pearls accordingly or convey that information to prospective buyers.

The value of a pearl, in part, is based upon its ability to absorb, refract and reflect light. It is the ability of the nacre to do that which creates that distinctive quality of natural and cultured pearls. That special glow, called orient defines the value of a pearl. The deeper the luster and iridescence, the more precious the pearl. Other things which contribute to the value of a pearl are:

~ Size: Larger pearls are scarcer so they are more valuable.
~ Shape: Symmetrical pearls are scarcer, so they are more valuable. Symmetrical pearls can be any number of shapes including: round, pear, tear, and oval. Irregular pearls are called baroque.
~Surface Perfection: The smoother, silkier pearl is harder to find, and so, more valuable. Blemishes which detract from a pearl's value are visible to the naked eye.
~ Rarity: Pearls which are matched in orient, size, shape and color are limited and, therefore, are rare.
