Pearls

Size

Size is a large factor in valuing pearls and has a significant impact on price.  Generally, the bigger the pearl the more valuable it is.  The size of a pearl is calculated by measuring its diameter in millimeters.  Sizes range from 2 millimeters (mm) to 18 mm.  The same type of pearl in sizes up to 5mm do not vary greatly in price.  However, after 6mm each 1mm  can increase the price from 50 to 100%.

Color

Pearls range in a palette of colors and shades to choose from.   A key factor in the color is the type of oyster or mussel. Depending on the geographical area there will be mollusks which produce different colors. The color of a pearl is a matter of personal taste. Some shades are rare and highly valued, such as rosy white, silvery white and pale gold.  However, the color of a pearl is not an indication of  the quality in valuing pearls..

Care

Cleaning pearls:

• Clean pearls by wiping with a soft damp cloth. For hard-to-remove film or dirt, use mild soapy water and then use a damp cloth with clean water to rub over the pearls.
• After clearing pearl jewelry, blot it with a soft cloth or air dry fully before putting away. This will prevent the silk string from stretching and loosening the pearls.
• If you scratch a pearl, use olive oil to gently rub on the scratched area.

And remember “last on, first off” when it comes to pearl jewelry.

Storing pearls:

• Store pearl jewelry in a soft fabric bag or a satin pouch
• Keep pearls stored separately from other jewelry
• Avoid very dry conditions to prevent pearls from dehydration
• Avoid direct sunlight exposure
