(Guide) How to store pearls: simple steps to stop scratches and colour loss

A single scratch or a stray perfume drop can dull a favourite strand of pearls overnight. If you cherish pearls but worry about scratches, discolouration, and fading lustre, this guide explains how simple habits and smart storage preserve their beauty.

We begin by explaining how pearls form and why their nacre makes them vulnerable, then cover daily wear precautions, gentle cleaning and safe drying, plus travel storage tips. Follow these practical steps and occasional professional care to keep pearls glossy, protect their colour, and ensure they last for generations.

Understand pearl structure and vulnerabilities

Pearls consist mainly of calcium carbonate platelets bound by the protein conchiolin, which gives them a soft hardness around 2.5 to 4.5 on the Mohs scale, so they scratch far more easily than gemstones or metals. Stacked aragonite layers in the nacre produce lustre and iridescence through light interference, so when nacre thins or wears away the bead nucleus can show through, reducing depth and colour. Because nacre and conchiolin are porous and chemically reactive, acids, solvents, perfumes, hairsprays, and some cosmetics can dull or etch the surface. They also abrade when rubbed against other jewellery, rough fabrics, or hard edges, so even contact with other pearls accelerates surface wear and loss of shine.

Silk or nylon threads absorb body oils and sweat, which can stain and weaken the string, so inspect knots and restring when threads show fraying. Store necklaces flat and separate from other pieces, ideally in soft pouches or lined compartments, to reduce friction, strain, and mould risk. Avoid extreme humidity, dryness, or heat because those conditions can stress nacre and threads, and remove pearls before applying cosmetics or doing household tasks to limit chemical exposure.

Protect pearls during daily wear

Put pearls on last, after applying makeup, perfume, and hair products, because solvents and acids in these items can strip the nacre and reduce lustre through direct contact. Remove pearls before exercise, swimming, showering, or household chores, as sweat, chlorinated water, and abrasive surfaces can dull the surface and weaken the string. After wearing, wipe pearls with a soft, slightly damp cloth to remove oils and perspiration that attract dirt and can cause discolouration or fibre weakening over time.

Keep pearls away from watches and rings while wearing, and avoid pairing them with harder jewellery, because glass, metal, and gemstones will scratch the relatively soft surface. Ensure strands have knots between each pearl and check the string and clasp regularly, since knots stop beads rubbing together. Inspect the thread for fraying, and note any looseness or slipping of beads. Restring when beads feel loose to reduce the risk of loss.

Clean pearls gently and dry safely

Wipe pearls after wearing with a soft, lint-free cloth dampened with plain water, or use a drop of mild, pH-neutral soap to remove greasy residue, then rinse the cloth and pat beads dry. Avoid ammonia, bleach, vinegar, and abrasive cleaners, because acids and harsh chemicals can etch the nacre and strip colour. Dry strands flat on a soft towel with air circulation, and do not hang wet necklaces or expose them to direct sunlight or heat, since wet silk threads can stretch and weaken and create gaps between beads.

Store pearls separately from metal and gemstone jewellery in a soft cloth pouch or fabric-lined compartment, avoiding airtight plastic, because friction, off-gassing, and trapped moisture can cause scratches and discolouration. Put pearls on after perfume, makeup, and hair products, since skin oils help maintain lustre while cosmetics and sprays deposit residues that dull colour, and wipe them after wearing with a clean cloth dedicated to pearls. Inspect the string and re-string when beads move freely or the thread shows wear, and ensure a knot between each pearl to prevent rubbing and limit loss if the strand breaks.

Store and protect pearls when travelling

Wrap each pearl piece individually in a soft, breathable cloth or a padded compartment to prevent friction with metal or other jewellery, because rubbing wears away the nacre and causes scratches and loss of lustre. After wearing, wipe pearls with a soft, slightly damp cloth and allow them to air dry, as sweat, sunscreen, and cosmetics contain acids and oils that can discolour or erode the nacre if left on. Include a moisture-absorbing sachet in the storage pouch to control humidity, but avoid long term airtight sealing since the pearls' organic components can crack if they dry out completely.

Keep pearls in your hand luggage and place them in a cushioned pocket or flat compartment to avoid crushing, extreme temperature changes, and rough handling that can weaken the string or crack the surface. Fasten clasps and lay necklaces flat, or store each strand separately to prevent tangles and undue strain on the thread. Inspect the string and knots before travel and loosen tight wraps to reduce tension during transit. Handling and storage routines like these reduce mechanical wear and preserve colour and lustre without requiring special chemicals or treatments.

Maintain pearl lustre with professional care

Have a professional check your pearls for thread tension, knot security, and drill hole wear, and re-string when beads begin to move loosely, because unchecked movement lets pearls rub together and abrade the nacre. Ask for a written condition report and full records of any conservation or enhancement, as some treatments can alter colour, lustre, and future preservation choices. Those records help you and the specialist monitor nacre thickness and surface integrity so interventions remain appropriate.

Before professional attention, wipe pearls with a soft, slightly damp cloth to remove oils, cosmetics, and sweat, then lay them flat to dry on a soft surface, since removing surface deposits reduces the need for aggressive treatment. When you request cleaning, insist on pH neutral, low abrasion methods under magnification and avoid ultrasonic, steam, or solvent baths because strong vibrations, heat, and chemicals can delaminate nacre and fade colour. Store pearls separately in a soft, breathable pouch or lined box and avoid airtight plastic, which can trap moisture or off gas substances that dull the surface sheen. These simple routines limit cumulative wear and help preserve natural lustre without unnecessary intervention.

Consistent, gentle care preserves pearls' nacre and lustre because avoiding acids, abrasives, and friction stops the thin aragonite layers from wearing away. Simple habits, such as putting pearls on last, wiping them after wear, and storing each piece in soft, breathable compartments, reduce chemical exposure and mechanical abrasion, so strands retain colour and structural integrity.

From daily wear precautions to gentle cleaning, safe drying, travel storage, and periodic professional checks, these practices limit surface wear and maintain depth of colour. Inspect threads, insist on pH-neutral, low-abrasion treatments, and re-string when beads move freely so you can preserve the natural sheen and pass pearls on with confidence.
