Wearing Pearls in Hot or Humid Climates: What to Know
If you live somewhere warm, or you are packing for a beach vacation, you might wonder whether your pearls will cope with the heat. The good news is that warm weather is no reason to stop wearing them.
Pearls are fine to wear in hot and humid weather. What matters is the routine around them: wiping off sweat and sunscreen after wear, keeping them out of places that heat up, and letting strands dry fully before you put them away.
If you want something low-maintenance for warm weather, a pearl pendant on a chain is an easy option, since there is no silk thread to stay damp.
Pearls are organic gems, and many people have heard that they can be sensitive to their environment. In a hot climate, it is natural to wonder whether the heat, the humidity or simply sweating more will cause damage.
The concern is reasonable, but it is usually aimed at the wrong thing. Warm air on its own is rarely the problem. What affects pearls is what tends to come with it.
Humid air is not harmful to pearls on its own. Its real effect is indirect: you sweat more, and a strand takes longer to dry, so moisture and salt can sit at the knots and on the silk thread for longer.
Heat becomes a concern when it is intense and sustained. Pearls hold a small amount of natural moisture, and leaving them somewhere that gets very hot, like a parked car or a sunny windowsill, can slowly dry out the nacre.
Sweat and sunscreen are the two things to watch in a warm climate. Both can leave residue that dulls the surface over time, so the most useful habit is a quick wipe with a soft cloth every time you take your pearls off.
Putting pearls on last, after sunscreen, lotion and perfume have dried, keeps most residue off in the first place. Before storing a strand, let it air out at room temperature so the thread is completely dry. Our pearl care and maintenance guide covers cleaning and storage in more detail.
Pack pearls in a soft pouch in your carry-on, so they stay with you and away from other jewelry. Once you arrive, keep them out of direct sun in your room and take them off for swimming, the beach and saunas.
Saltwater, chlorine and sand are all harder on pearls than the heat itself. On beach or pool days, leave them somewhere cool and safe rather than in a bag that can heat up in the sun. For ideas on wearing pearls through the warmer months, see our summer jewelry guide.
One common mistake is assuming humid weather means pearls should not be worn at all. In reality, regular wear with good habits suits pearls better than leaving them sealed away somewhere very dry.
Another is putting pearls away straight after a hot day. A strand that feels dry on the surface can still be damp at the knots, so give it time to air out first.
If you would like a closer look at how each factor affects pearls and what to do in different situations, or a full cleaning and storage routine, these guides cover both in depth.

Yes, for dinners, sightseeing and time away from the water. Take them off for swimming, sunbathing and the beach itself, where saltwater, sand and sunscreen are harder on them, and leave them somewhere cool and safe rather than in a beach bag.
Not on its own. Dullness in humid places usually comes from sweat and products building up on the surface, which a wipe after each wear helps prevent.
Once they are fully dry, keep them in a soft, breathable pouch at room temperature. Avoid airtight bags and anywhere that gets hot, like a sunny shelf.
Check strands regularly for loose knots, gaps between pearls or a strand that has stretched. If you notice any of these, take them to a jeweler to be restrung.
“In warm climates, I tell people not to change whether they wear their pearls, just how they look after them. A wipe after every wear does more than anything else.”

Hot and humid weather is no reason to put your pearls away. Wipe off sweat and sunscreen, keep them out of hot cars and direct sun, and let strands dry before storing them, and they will handle a warm climate well.
