How to Clean and Care for Pearl Jewelry

Pearls are the softest, most delicate stones in any jewelry box, and almost every pearl owner accidentally damages them. They scratch against hard jewelry, dull against perfume, and absorb moisture that rots the silk they are strung on. Yet pearls are also the most rewarding to care for, because a well-kept strand looks luminous for generations, while a neglected one goes chalky and dull in a few years. The good news is that pearl care is simple once you know the rules. The bad news is that almost everything you do to clean other jewelry is wrong for pearls.

This guide explains how to clean pearls, how to store them, how to tell when the string needs re-threading, and what to avoid. It is written for akoya, freshwater, South Sea, and Tahitian pearls, whether in a strand, a pendant, or earrings.

Why Pearls Need Different Care

Pearls are organic. They are made by oysters, layer by layer, of nacre, a mother-of-pearl substance. Nacre is soft, around 2.5 to 4.5 on the Mohs scale, far softer than gold or diamonds. It is also porous, meaning it absorbs liquids. Perfume, hairspray, lotion, and even vinegar in salad dressing can seep into the nacre and cloud it. Sweat is mildly acidic and slowly eats away at the surface. This is why pearls need a gentler routine than any other jewelry.

The lustre of a pearl is its life. Lustre is the soft glow that seems to come from inside the pearl. When the nacre surface is clean and smooth, the pearl glows. When it is clouded by chemicals, the glow dies and the pearl looks chalky. Once lustre is gone, it cannot be restored. So pearl care is really lustre protection: keep chemicals off, keep the surface clean, and the glow lasts decades.

The Right Way to Clean Pearls

After every wearing, wipe your pearls with a soft, dry, lint-free cloth. A chamois or a purpose-made jewelry cloth is ideal. This removes the skin oils and sweat that would otherwise sit on the pearl all night. Do this while the pearls are still on your neck or wrist, before you take them off, so you do not forget. This single habit is the most important thing you can do for a pearl strand.

Once every few wears, clean more thoroughly. Use a barely damp soft cloth with a drop of very mild, pH-neutral soap. Wipe each pearl gently, then wipe again with a clean damp cloth to remove soap, and pat dry. Do not soak pearls. Water seeps through the drill holes and into the silk string, which weakens it and can discolor the nacre from inside. Never put pearls in an ultrasonic cleaner, a steam cleaner, or a jewelry dip. Those destroy pearls. Our ultrasonic guide explains which stones they are safe for, and pearls are not on the list.

What Never to Do to Pearls

Never spray perfume or hairspray while wearing pearls. Apply these first, let them dry, then put the pearls on. Never apply lotion or hand cream while wearing a pearl ring or bracelet. Never wear pearls in the shower, the pool, or the ocean. Chlorine, soap, and salt water all damage nacre. Never use toothpaste, baking soda, or silver polish on pearls; these abrasives scratch the soft surface. Never store pearls with other jewelry, because hard rings and chains scratch them.

Never let pearls sit in direct sunlight or near a heater. Heat dries out the nacre and the silk string, causing cracking and brittleness. Never store pearls in an airtight plastic bag for years; they need a little air. The ideal storage is a soft cloth pouch or a lined jewelry box compartment, away from other pieces, at room temperature. Our storage guide covers the setup.

The Silk String Needs Replacing

A pearl strand is strung on silk, knotted between each pearl. Over years, the silk stretches, absorbs oils, and weakens. A strand that is two or three years old and worn regularly should be re-threaded. You can tell it is time when the silk looks stretched, gray, or frayed, or when the knots between pearls are no longer tight. A broken strand scatters pearls across the floor, some of which will chip or roll away forever.

Re-threading is inexpensive and should be done by a professional pearl stringer, not a general jeweler. The silk is knotted between each pearl, which both spaces them and prevents them from scratching each other. Do not knot pearls yourself unless you know how. A knotted strand is also safer: if it breaks, only one pearl falls rather than the whole strand scattering. Our repair guide covers when to see a professional.

Pearls in Rings and Earrings

Pearl rings take the most abuse, because the ring hand touches everything. A pearl ring should be worn on special occasions, not daily. Take it off before washing, typing, or lifting. Pearl earrings last longer because the earlobe is gentler, but still wipe them after wearing and keep lotion off the posts. Pearl pendants sit on the chest, away from the hands, and survive the best of all.

When pearls are set in metal, check the setting. A pearl held in prongs can chip if the prong presses into it. A bezel setting is safer for pearls. If you are buying a pearl ring, choose a protective setting. Our setting guide explains which settings protect soft stones.

How to Tell Good Pearls From Chalky Ones

A healthy pearl has deep lustre: turn it in the light and you see a soft glow, and you can almost see your reflection in it. A worn pearl looks chalky, flat, or whitish rather than lustrous. If you see flaking or peeling on the surface, the nacre is wearing off and the pearl cannot be restored. Fine cultured pearls have thick nacre and last decades; cheap imitation pearls have a thin coating that wears off in years. Buy real cultured pearls, and they will outlast you.

If your pearls have gone slightly dull, a professional can re-buff them gently, but this removes a tiny layer of nacre and should be done rarely. Prevention is far better. Wipe them after each wearing and the lustre stays for decades. Our professional cleaning guide covers what a jeweler can safely do.

Wearing Pearls Everyday

Pearls love to be worn. Contrary to the idea that they should sit in a box, pearls stay healthier when worn, because the natural oils on your skin feed the nacre. A strand worn regularly and wiped after each wearing glows more than one locked away. The key is not to stop wearing them, but to care for them as you do. Put pearls on after makeup and perfume, take them off before showering, and wipe them each time.

If you only wear pearls on special occasions, take the strand out of the box once a year and lay it in the air. Pearls sealed in a box for decades can dry out. A few hours of air and a gentle wipe keeps them alive. Treat them as living jewelry, because they once were. Our birthstone guide notes pearls as the June birthstone, a classic gift for that month.

Storing Pearls So They Last

Pearls are scratched by almost everything. Store them in their own soft pouch or a separate compartment, never loose in a drawer with rings and chains. A pearl rubbing against a diamond ring for a night gets micro-scratched that cloud its lustre over time. Silk pouches or velvet-lined rolls are ideal. Hang a long strand loosely rather than folding it, because folding creates a permanent kink in the silk.

Avoid storing pearls in a safe deposit box for years on end, because the dry air dries them out. If you do store them long-term, wrap them in a slightly damp cloth every year to keep the nacre from cracking. Keep them away from direct sunlight and heat vents. Pearls like the same conditions you do: room temperature, not too dry, not too hot. Our storage guide covers the whole setup.

Buying Pearls That Will Last

The care routine only works if the pearls themselves are good. Imitation pearls, usually plastic coated with a thin pearlescent layer, wear in months. Real cultured pearls have thick nacre and last decades. When you buy, look for deep lustre, smooth surfaces, and consistent shape. Avoid pearls that look plastic or chalky, and avoid bargain strands. A good pearl strand is a lifelong piece, not a fashion accessory. Our gemstone buying guide applies the same care to buying.

When pearls are strung, confirm the silk is knotted between each pearl. A non-knotted strand is cheaper but scratches the pearls and loses them if it breaks. Insist on knotted silk. Also ask whether the clasp is a secure lobster or a simple ball; a secure clasp prevents losing the whole strand. These details matter as much as the pearls themselves. Our necklace guide covers strand lengths and clasps.

Repairing and Restoring Pearls

Pearls can rarely be repaired, only re-threaded or re-strung. If a pearl chips, it cannot be polished out the way a diamond can. A chipped pearl can sometimes be drilled to remove the chip, but that reduces its size. If a strand breaks, gather the pearls immediately and take them to a stringer; most can be re-threaded onto new silk. Do not attempt to knot pearls yourself, because a poorly knotted strand scratches the pearls and weakens the silk.

If pearls have gone dull, a professional can gently re-polish the surface with a very mild compound. This works only on pearls that still have thick nacre. On cheap pearls, it would wear through the coating. Ask the stringer honestly whether re-polishing is worth it. Often the best answer is to leave the pearls as they are, because gentle polishing removes material. Our repair guide covers what is fixable.

A Quick Pearl Care Routine

To make this easy, build a tiny routine. When you take pearls off at night, wipe each pearl with the soft cloth you keep in the pouch. Lay the strand flat or hang it, never folded. Once a month, lay it out and inspect the silk for fraying. Once every two to three years, take it to be re-threaded. Never spray perfume near it, never shower in it, never store it with other jewelry. That is the whole routine. It takes a minute a day and keeps the pearls glowing for decades.

If you travel with pearls, roll the strand in a soft cloth and pack it on top of your clothes, not at the bottom where things press on it. Our travel packing guide covers the details. Pearls are tough when cared for gently; they are fragile when treated like metal jewelry. Treat them as the organic, living gems they once were, and they will serve you beautifully.

Pearl Types and Their Care Differences

Not all pearls are cared for identically. Akoya pearls are small, round, and lustrous, with thin nacre that scratches easily. Freshwater pearls are usually more durable and more affordable, with thicker nacre. South Sea and Tahitian pearls are large, expensive, and have thick nacre, but their surface is still soft. In every case, the rules are the same: wipe after wearing, keep chemicals away, and re-thread the silk. The value of the pearl only makes the care more important; you do not want a cheap mistake to cloud a Tahitian strand.

Imitation pearls need no such care, because they are plastic. But they also do not glow like real pearls, and they chip. If you are investing in real cultured pearls, treat them with the respect their organic nature deserves. A real pearl, cared for, outlasts a hundred plastic ones.
