Pearls require much more caution than many common gemstones.

Pearls are organic gemstones and have a relatively delicate surface.

They should generally not be treated like hard gemstones such as diamonds.

Avoid:

• Harsh chemicals
• Abrasive cleaners
• Prolonged soaking
• Strong household cleaning products
• Ultrasonic cleaning unless specifically approved by a professional

After wearing pearls, gently wipe them with a soft, slightly damp cloth.

Allow them to dry before storage.

Pearls are also sensitive to substances such as perfume, hairspray, and cosmetics.

A good rule is to put perfume and cosmetics on first, allow them to dry, and then put on your pearl jewelry.

What About Opals?

Opals deserve special care.

They can contain significant amounts of water and may be more sensitive to heat, sudden temperature changes, and certain cleaning methods.

Avoid experimenting with strong cleaners or extreme temperatures.

A soft, damp cloth may be a safer choice for many opal pieces.

If the opal is particularly valuable, antique, or has a special treatment, professional advice is preferable.

What About Turquoise?

Turquoise can be porous and may be affected by oils, chemicals, cosmetics, and some cleaning products.

Avoid soaking turquoise jewelry in unknown solutions.

A gentle wipe with a slightly damp soft cloth may be more appropriate.

The exact care depends on the stone and whether it has been treated.

What About Costume Jewelry?

Costume jewelry can be especially unpredictable.

It may contain:

• Base metals
• Plating
• Glass
• Plastic
• Synthetic stones
• Glued components
• Decorative coatings

Water can sometimes seep into areas where stones or decorative components are attached with adhesive.

As a result, prolonged soaking may cause problems.

For many costume jewelry pieces, a lightly dampened cloth is safer than immersing the entire item.
