Summer Pearl Care: 5 Mistakes That Ruin Your Jewelry

Pearls are summer’s natural companion—they reflect light, feel cool against the skin, and pair effortlessly with bare shoulders and linen. But they’re also far more delicate than your average gold chain. A single sunny afternoon, if you’re not careful, can strip a pearl of its luster permanently.

That’s not a reason to leave your pearls at home. It’s a reason to know exactly what hurts them so you can wear them confidently—from beachside brunches to rooftop dinners. Here are the five most common summer pearl mistakes and how to avoid them.

Mistake #1: You’re applying sunscreen (or body oil) with your pearls on

Pearls are porous. Sunscreen, tanning oil, and even some moisturisers seep into the nacre—the iridescent layer that gives pearls their glow—and create a dull, sticky film that’s difficult to remove without professional cleaning.

The fix: Make pearls the last thing you put on and the first thing you take off. Apply all lotions, sprays, and perfumes at least 10 minutes before you wear your jewellery. At the end of the day, gently wipe each pearl with a soft, lint-free cloth—nothing rougher than a glasses cloth—to remove any residue before storing.

Mistake #2: Swimming in chlorine or saltwater

Chlorine eats into the nacre so aggressively that a single swim can create permanent rough spots and loss of colour. Saltwater is equally damaging: it dries into microscopic crystals that scratch the surface and can corrode the silk thread most pearl necklaces are strung on.

The fix: Never wear pearls into a pool, hot tub, or the ocean. If you’re heading to the beach, pack a small jewellery-safe pouch and take them off the moment you arrive. It’s the one piece of jewellery that truly shouldn’t touch vacation water.

Mistake #3: Leaving pearls in direct sunlight for hours

Sunlight won’t melt a pearl, but it will gradually dehydrate it. Over time, intense UV exposure can cause pearls to develop tiny cracks (called crazing) and lose their subtle water-like sheen.

The fix: When you’re not wearing them, store pearls away from windowsills, dashboards, or any spot that gets direct afternoon sun. A lined jewellery box or a soft pouch in a drawer is ideal. If you’re outdoors all day, consider a necklace that sits under a collar or a hat for extra shade.

Mistake #4: Wiping pearls with a rough cloth after a sweaty day

It’s natural to want to clean your jewellery after a humid afternoon. But a dry paper towel, terry cloth, or even a sleeve can leave fine scratches on the pearl’s surface. Sweat, while slightly acidic, is less damaging than the abrasion of a rough wipe.

The fix: Use a barely damp, super-soft microfiber or chamois cloth to gently pat the pearls dry. Then let them air-dry fully before putting them away. Never rub. If you’ve been sweating heavily, the cloth can be slightly moistened with distilled water—no soap, no detergent.

Mistake #5: Storing pearls in a hot, dry place (or a sealed plastic bag)

Pearls need a whisper of moisture to stay supple. A safe, a car glove box, or a sealed plastic bag creates a dry, airless environment that can lead to brittleness and cracking over time. Silk thread also becomes brittle and snaps faster in very dry conditions.

The fix: Store your pearls in a soft pouch or a fabric-lined jewellery box at room temperature. If you live in a very dry climate, you can place a small, barely damp cotton ball in the room (not directly touching the pearls) to introduce a little humidity. Avoid direct contact with any moisture source.

Quick Facts

• Pearls are organic gems; their nacre ranks just 2.5–4.5 on the Mohs hardness scale, making them softer than glass.
• Sunscreen, perfume, and hairspray should always be applied before you put on pearl jewellery.
• Chlorine can cause irreversible damage to pearls in a single exposure.
• Saltwater leaves tiny abrasive crystals that scratch both the pearl surface and the stringing silk.
• A soft, damp cloth is the only safe DIY cleaning tool; never use jewellery dips or ultrasonic cleaners.
• Storing pearls in a very dry environment can cause them to crack; a little ambient humidity is helpful.
• If moth-of-pearl or pearl jewellery gets wet with fresh water, pat it dry immediately and let it air-dry flat.

FAQ

Can I wear pearls at all on a beach day? Yes, but wear them only when you’re settled and away from water and sand. Put them on after sunscreen has dried, take them off before any swimming, and don’t let them sit in the sand. A small padded pouch in your beach bag makes removal easy.

How do I clean sunscreen off my pearls? Use a cloth lightly dampened with distilled water. Gently wipe each pearl, then buff with a dry, soft cloth. Avoid rubbing or pressing hard. If the film remains, have a professional jeweller clean them—never use household cleaners.

Will saltwater really ruin my pearls with one splash? A single splash might not ruin them instantly, but salt crystals that dry on the surface can scratch the nacre. Over time, repeated exposure weakens the lustre. The safest rule is to treat saltwater like chlorine: keep pearls away.

Is it safe to store pearls in the bathroom? It’s better than a very dry safe, but the humidity swings from showers can stress the silk thread. A bedroom drawer with stable, moderate humidity is a more reliable choice.
