Care for your Pearls

Caring For Pearls 

The softness of pearls and their low resistance to heat and chemicals mean that special precautions must be taken when cleaning them.  Keep in mind the following guidelines:

·         Do not use commercial jewelry cleaners on pearls unless the labels say they are safe for pearls.  Many of them contain ammonia, which will cause deterioration.

·         Never clean pearls in an ultrasonic cleaner.  It can damage the pearls and wash out the color if the pearls have been dyed.

·         Never steam-clean pearls,  Heat can harm them.

·         Never use detergents, bleaches, powdered cleaners, baking soda or ammonia-based cleaners on pearls

·         Do not use toothbrushes, scouring pads or abrasive materials to clean pearls They can scratch their surface.  If there’s a lump of dirt that can’t be rubbed off with a soft cloth, try using fingernails.  They have hardness of only 2.5 or less

Cleaning Pearls is not complicated.  After you wear them, just wipe them off with a soft cloth or chamois, which can be dry or damp.  This will prevent dirt from accumulating and keep perspiration, which is slightly acidic, from eating way at the pearl nacre.

If the pearls have not been clean and are very dirty, they can be cleaned by your jeweller or they can be washed in water and a mild soap such as Ivory or Lux liquid (some liquid soaps, such as Dawn, can damage pearls) and cleaned with a soft cloth.  Pay attention to areas around the drill holes where dirt may tend to collect. After washing them, lay the pearls flat in a moist kitchen towel to dry.  After the towel is dry, they should be dry.  Do not wear pearls when their string is wet.  Wet strings stretch and attract dirt which is hard to remove.  Likewise do not hang pearls to dry.

 

Storing your Pearls

Pearls are composed of about 2 to 4% water along with calcium carbonate and an organic binder called conchiolin.  If the pearls become dehydrated, they can get brittle and crack.  Consequently, they should not be kept near heaters or in places that get some sunlight, such as a window sill.  Safe deposit boxes can be usually dry, so if you ever store pearls there, try to take them out occasionally and expose the to humidity or moisture.  Sealed plastic bags are not the best for pearls.  They can keep them from breathing and getting moisture.

Since pearls are soft, they should be kept in something that will protect them from scratches.  Jewelry pouches or cloth bags are ideal.  Pearls can also be wrapped in soft material and kept wherever convenient.  Jewelry boxes may be handy, but they are also the first place burglars look.

Having your Pearls Strung

 

Pearl necklaces can scretch with time and the string can get dirty and weak. Thus, they should be restrung periodically – about once a year, but that depends on how often they are worn.  Fine pearls should be strung with silk and with knots tied between each pearl.  This prevents them from rubbing against each other and from scattering if the string break.

Occasionally pearls are strung with gold beads.  According to a Los Angeles pearl stringer, gold turns pearls ivory color and coral black, and this is a permanent discoloration.  Therefore, its not advisable to string expensive pearls with gold beads.

Miscellaneous Tips:

·         Take your pearls off when applying cosmetics, hair sprays and perfume.  Those beauty aids are made of chemicals and acids, which can harm your pearls

·         Take your pearls off when showering or swimming.  It’s not good to get the string wet, plus chlorine or soap can damage the pearls.  Pearl rings should be taken off when washing your hands or dishes.  Put thit won’t accidentally fall in the draine ring in a protective container or safe spot where it won’t accidentally fall in the drain or get lost

·         When selecting Pearls jewelry, check to see if the pearl is mounted securely.  Preferably, the pearl will have been drilled and glued to a post on the mounting, especially if it is a ring.  Otherwise, the pearl may come loose.  If the pearl is flawless, a drill hole could lower its value.  In such a case, it would be safer to set the undrilled pearl in a pin, pendant or earring than a ring.

·         When taking off a pearl ring, grasp the shank or metal part rather than the pearl.  This will prevent the pearl from loosening and coming into contact with skin oil on your hand.

·         Avoid wearing pearls with rough fabrics such as Shetland Wool. They can scratch the pearls.

·         About every six months, have a jewelry professional verify the pearls on your jewelry are securely mounted or that the string is still good.  Many jewelers will do this free of charge and they will be happy to answer your questions regarding the care of your jewelry.
