Pearl FAQ’s

Why should I buy my cultured pearls at David Orgell?
Because cultured pearls of high quality are increasingly rare today, it is important that you deal with a jeweler you trust. At David Orgell, we currently offer Mikimoto cultured pearls.
 
Is there a grading system?
Unlike diamonds, cultured pearls are not evaluated by an industry-wide grading system. However, some merchants, including Mikimoto, have developed their own grading scales for comparative purposes. Because we believe quality is so crucial in cultured pearls, David Orgell offers only those cultured pearls that would be considered the highest grades at other stores.
 
Why are two different strands of the same length priced differently?
Many factors including quality, size, and luster affect the price of a pearl strand. Larger cultured pearls are rarer and far more difficult to match than smaller ones.
 
How do I care for my cultured pearls?
Fine cultured pearls with thick nacre layers will last for generations if cared for properly. Avoid having your cultured pearls come into contact with perfumes, cosmetics, perspiration and dirt. We suggest that you gently wipe cultured pearls with a slightly damp cloth. All cultured pearls available at David Orgell are strung on pure silk. If you wear your cultured pearls regularly, we encourage you to have your cultured pearls cleaned and restrung annually.

What is a Pearl?
A pearl is a byproduct of the partnership between nature and chance.
 
When a foreign object, such as a grain of sand, is trapped in an oyster or mussel, it is coated with layers of a smooth, crystalline substance known as nacre. Over time, this natural process produces the luminescent gem we know as a pearl.
 
Nearly all pearls sold today are cultured. That is to say, each one is created by deliberately inserting an irritant into the oyster's tissue. However, the quality of cultured pearls varies widely.
More than any other factor, size determines price. Pearl size is the result of the size of the implanted nucleus plus the thickness of the nacre, which grows layer by layer. A large cultured pearl is of little value if it lacks nacre thickness since a thinly coated cultured pearl will crack and discolor. Nacre thickness can be verified only by an expert.
 


Perfectly round cultured pearls are the rarest. While most cultured pearls are basically round, only about 1% are perfect spheres. To check a strand, roll it on a flat surface. The movement should be even and smooth.
 


Pearls occur in a spectrum of shades. The major classifications are white, pink, silver, cream, gold and black. Fine cultured pearls will also have a secondary color or "overtone" — usually rose, green or blue — around the outside of the pearl. Traditionally, cultured pearls with pinkish-white or pinkish-silver coloring are the most highly prized. Whatever the color, it should appear to emanate from deep within the cultured pearl.
 


A small percentage of cultured pearls display rainbow-like colors that appear to move over the surface.
 


Luster refers to the surface shine that gives cultured pearls their glowing beauty. Stand with your back to the light; the sharper the reflection of light on the cultured pearl, the higher the luster.
 


Like any product of nature, all cultured pearls have imperfections. However, a quality cultured pearl should be free of large pits or blemishes.
