珍珠 Care 指南 — Dos與Don'ts
Quick answer: put pearls on after cosmetics and fragrance, remove them before showering, swimming, exercise, or cleaning, wipe them with a very soft cloth after wear, and store them away from harder jewelry. Pearl ranks about 2.5 on the Mohs hardness scale, so scratching, heat, acids, and harsh cleaning methods require particular care.
The four rules that prevent most pearl damage
- Last on, first off. Finish perfume, hair spray, lotion, and makeup before putting pearls on; remove pearls first when undressing.
- Wipe after wear. Use a very soft, clean cloth to remove skin oils and cosmetic residue.
- Keep pearls away from harsh methods. Never use an ultrasonic or steam cleaner, abrasive paste, ammonia, bleach, or jewelry cleaner intended for diamonds.
- Store separately. Use a soft pouch or lined compartment so metal edges and harder gemstones cannot scratch the nacre.
What to avoid and why
| Avoid | Risk | Safer choice |
|---|---|---|
| Perfume, hair spray, cosmetics, and household chemicals | GIA notes that pearls can be damaged by many chemicals and acids. | Apply products first, let them dry, then put pearls on. |
| Ultrasonic and steam cleaners | These methods are not suitable for pearls. | Use a very soft cloth; for a deeper clean, use warm mildly soapy water as described below. |
| High heat or intense light | Heat can discolor, split, crack, or dehydrate nacre. | Keep pearls away from hair tools, radiators, direct sunlight in storage, and a jeweler’s torch. |
| Contact with harder jewelry | Pearl is soft and scratches comparatively easily. | Use a separate soft pouch or lined compartment. |
| Wearing a wet strung necklace | Moisture can remain in the thread and drill holes. | Lay it flat and allow the string to dry completely. |
How to clean pearl jewelry safely
For routine care, GIA recommends wiping cultured pearls with a very soft, clean cloth after each wearing. When a more thorough clean is genuinely needed, use warm, mildly soapy water and a soft cloth. Do not scrub. Remove soap residue with another clean, damp cloth.
For strung pearls, avoid soaking. Lay the strand flat on a towel and make sure the thread is completely dry before wearing it. If the piece includes adhesive, delicate antique components, porous stones, or an unfamiliar setting, ask a qualified jeweler before introducing water.
How to store pearls
- Store pearls in a soft pouch or fabric-lined compartment, separate from diamonds, metal edges, and other harder materials.
- Lay strung necklaces flat so the thread is not held under constant tension.
- Close clasps before storage to reduce tangling and abrasion.
- Avoid high heat, very dry long-term conditions, and direct intense light.
- Keep the jewelry box clean; residue inside a pouch can transfer back to the pearl.
When to inspect or restring a necklace
A fixed “every few years” rule is too broad because wear frequency, thread, weight, knots, drill holes, and storage conditions differ. Inspect a strand regularly. Seek professional restringing if the thread is stretched, frayed, darkened, or visible between pearls; if knots have loosened; if pearls move against one another; or if the clasp no longer closes securely.
For a valuable strand, ask the jeweler what thread and knotting method they will use and whether they will check the clasp and drill holes at the same time. Do not attempt to polish away a deep scratch or crack at home.
Care by jewelry type
- Stud earrings: wipe the pearl and the post separately; check that the cup and post remain secure.
- Rings: remove before handwashing, housework, exercise, and sleep because rings receive more knocks and chemical exposure.
- Pendants: check the bail and any adhesive or cup holding the pearl.
- Strands: inspect thread, knots, clasp, and the pearls nearest the clasp, which often receive the most handling.
Primary care reference
The safety guidance above follows the Gemological Institute of America’s pearl care and cleaning guide. Treatment and disclosure terminology is cross-checked against the U.S. Federal Trade Commission Jewelry Guides. Product-specific instructions from a qualified jeweler take precedence where a piece includes other gems, adhesives, antique materials, or a special setting.
Frequently asked questions
Can I shower or swim with pearl jewelry?
Remove pearl jewelry before showering or swimming. Personal-care products, pool chemicals, heat, and prolonged wetting can affect the pearl, the setting, or a strung necklace.
Can pearls go in an ultrasonic or steam cleaner?
No. GIA advises that pearls should never be cleaned in an ultrasonic or steam cleaner.
How often should I clean pearls?
Wipe them with a very soft, clean cloth after wearing. Use warm, mildly soapy water only when a more thorough clean is needed, and make sure any string is completely dry before wearing.
How often should a pearl necklace be restrung?
There is no universal calendar interval. Inspect the thread, knots, clasp, and drill holes regularly. Ask a qualified jeweler to restring the necklace when thread is stretched, frayed, soiled, or the knots have loosened.
What should I do if a pearl is cracked or badly scratched?
Stop wearing the piece and ask a qualified jeweler or pearl specialist to inspect it. Deep nacre damage is not a safe do-it-yourself repair.
