How to Care for Pearl Jewelry the Right Way
Pearls are among the most delicate of all gemstones — not because they're fragile in structure, but because they're organic. Made of calcium carbonate (aragonite) and an organic protein called conchiolin, pearls can be damaged by chemicals, heat, and even excessive dryness. With proper care, however, they can last for generations and actually become more beautiful with time.
Understanding What Damages Pearls
Before diving into care routines, it helps to know what to avoid:
- Acids and chemicals: Perfume, hairspray, makeup, sunscreen, and household cleaners can erode pearl nacre over time.
- Ultrasonic cleaners: The vibrations can crack or separate nacre layers — never use these on pearls.
- Steam cleaning: Heat and steam can dry out and crack the organic material in pearls.
- Abrasives: Even a rough cloth can scratch the surface of a pearl.
- Extreme dryness: Very low humidity environments can cause pearls to crack over time.
- Prolonged water exposure: Soaking pearls, especially stranded ones, weakens the silk thread and can loosen knots.
How to Clean Your Pearls
The good news: cleaning pearls is simple. You don't need special equipment or expensive solutions.
- After every wear: Gently wipe your pearls with a soft, slightly damp cloth (microfiber or lint-free cotton). This removes skin oils, sweat, and any cosmetic residue before it can build up.
- For deeper cleaning: Use a soft cloth dampened with lukewarm water. If needed, add a tiny drop of very mild, non-detergent soap. Gently wipe each pearl, then wipe again with a clean damp cloth to remove any soap residue.
- Drying: Lay the strand flat on a clean towel to dry completely before storing. Never hang a wet pearl strand — the weight can stretch the silk thread.
- Never soak: Even a brief soak can weaken silk thread in stranded necklaces and introduce moisture into knots.
The "Last On, First Off" Rule
A simple habit that protects your pearls more than almost anything else: put your pearl jewelry on last when getting ready — after perfume, makeup, and hairspray have been applied and settled. Take them off first when you get home. This dramatically reduces their exposure to chemicals.
Storing Pearls Properly
How you store your pearls matters as much as how you clean them:
- Store separately: Keep pearls away from other jewelry. Harder gemstones like diamonds, sapphires, and even gold prongs can scratch pearl surfaces.
- Use a soft pouch or lined box: A silk or velvet-lined pouch or compartment protects the surface and allows some breathability.
- Avoid airtight containers: Pearls need a little humidity. Sealed plastic bags or airtight boxes can dry them out over time.
- Don't store near vents or windows: Heat and direct sunlight can yellow and crack pearls over time.
Restringing: When and Why
Pearl strands should be restrung on silk thread, with a knot between each pearl. This prevents pearls from rubbing against each other and means that if the thread breaks, you won't lose all your pearls at once.
As a general guideline, have frequently worn strands restrung every one to two years, and less frequently worn pieces inspected by a jeweler every few years. Signs it's time to restring: visible looseness between pearls, a strand that stretches noticeably, or discoloration of the thread near the clasp.
Wearing Pearls Regularly: A Good Thing
One of the most charming facts about pearls: they actually benefit from being worn. The natural oils from your skin can help maintain their moisture and luster. Pearls left unworn in a dark box for years can become dull and brittle. So wear them — they'll thank you for it.
