| Historic pearls are known to be
several hundred years old and still retain their lustre. Clearly,
under the right conditions pearls can last for millennia. However,
it is important to understand the basics about their care.
Pearls are much softer than hard gemstones and can be easily scratched.
Because they contain organic material and water, pearls can also
crack if exposed to excessive dryness. In addition, acids and other
chemicals can easily damage pearls.
When the moment comes to put pearls away for the night, owners
should make it a habit of rinsing and drying them off. You may even
polish them with a soft cloth containing a drop of olive oil so
that they maintain their lustre and do not dry out.
To protect pearls:
- Store pearls in a soft cloth sack, separate from metallic necklaces.
- Never clean pearls in an ultrasonic cleaner.
- Do not use chemical cleaners, especially those containing ammonia
and bleach.
- Remove pearls before washing dishes, doing housework, or applying
perfume or hair spray.
- Put cultured pearls on after applying cosmetics, perfumes, and
other personal care products.
- Do not wear pearls in swimming pools with chlorinated water.
- Avoid contact with foods containing acids, e.g., fruit juices
and salad dressings.
- Expose pearls regularly to humid conditions. If stored in a
safe, place a glass of water in the compartment with them.
To keep pearls looking beautiful:
- Wipe with a soft cloth after wearing. This will prevent dirt
from accumulating and keep perspiration, which is slightly acidic,
from eating away the pearl nacre.
- Wash occasionally in mild soapy water and lay them out on a
moist towel to dry; contrary to popular belief, the acidic oils
and perspiration from human skin can damage the surface of a pearl.
- Dampen pearls with water from time to time and polish them with
a drop of oil.
- Have pearls restrung periodically (once every two years), especially
if worn frequently. It is best to use silk thread with knots tied
between the pearls to prevent abrasion and ensure that all are
not lost if the string is broken.
