Do you tuck your pearls into the same tray as rings and chains and wonder if they will survive unscathed? Because pearls are organic and much softer than metal, contact with hard surfaces, rough edges, and lotions can dull their lustre and cause scratches.
This post explains why pearls are delicate, how abrasion and chemical transfer harm them, and practical steps for cleaning, separate storage, humidity control, and restringing. Read on to learn simple routines and storage options that preserve colour, shine, and structural integrity so your pearls last.

Recognise why pearls are delicate
Pearls form from layered nacre, a calcium carbonate and organic matrix with a Mohs hardness around 2.5 to 4.5, so they are far softer than metals and most gemstones and will acquire surface scratches from contact with harder items rather than from normal wear. They also react chemically to acids in perspiration, perfume, and some cosmetics, which can etch the organic matrix, dull the surface, and cause irreversible discolouration. Because pearls are porous they absorb oils, lotions, and dyes; brief contact with natural skin oils can help maintain lustre, but prolonged exposure to cosmetics or coloured fabrics can produce stains and unpleasant odour.
Abrasion from chains, clasps, and hard gemstones gradually trims the outer layers of nacre, so avoid storage where pearls will rub against rough, pointed, or heavy settings. Necklaces left to hang with other items place tension on silk or nylon threads, which can stretch, weaken, and break. Lay pearl pieces flat and keep each item in individual soft pouches or lined compartments to prevent contact and minimise movement. Have strings inspected regularly and restrung when you see fraying, and avoid storing pearls next to dyed fabrics or cosmetics to reduce staining risk.

Prevent abrasion, scratches, and chemical transfer
Store pearls separately in soft-lined compartments or individual cloth pouches made of natural fibres, and use breathable fabric wraps or a lined jewellery box instead of sealed plastic bags or PVC, which can trap moisture and release chemicals that discolour the nacre. After wearing, wipe pearls with a soft, slightly damp cloth to remove sweat, cosmetics, and oils, then lay them flat to dry before storing, because residues can chemically alter the nacre and promote transfer of tarnish from nearby metals. Keeping pearls isolated prevents harder gemstones and metal from rubbing against the nacre and causing micro-scratches. Regular cleaning and breathable, soft storage together reduce the risks of surface degradation and colour change.
Keep pearl necklaces flat rather than hanging, and check the cord or silk regularly, since gravity and stretched thread increase bead contact and rubbing, which raises the risk of abrasion and strand failure. Store pearls separately from metals that tarnish, place a soft physical barrier between items, or keep anti-tarnish materials nearby, because metal sulphides can transfer colour and leave marks through contact. Periodic inspection of cords and storage conditions lets you spot early rubbing, tarnish transfer, or chemical residues so you can act before the nacre suffers lasting damage.

Clean pearls and remove contaminants before storing
Storing pearls with other jewellery risks scratches and discolouration because pearls are soft and their nacre can be etched or dulled by oils, acids, sulphur compounds, and solvents found in skin, perfume, hair spray, cosmetics, and chlorine. To remove these contaminants, wipe each pearl with a soft, lint-free cloth dampened with warm water and a drop of mild, pH-neutral soap, rinsing the cloth and repeating as needed, then lay the pearls flat on a soft towel to air-dry completely, since prolonged soaking can weaken silk and adhesives used in strung pieces. For loose pearls a brief, gentle bath followed by careful drying is acceptable, but for strung pearls avoid saturating the thread and inspect drill holes for wear after cleaning. These precautions reduce chemical and mechanical damage that leads to permanent discolouration or thread failure.
Avoid ultrasonic or steam cleaners, jewellery dips, alcohol, bleach, and abrasive brushes, because they can abrade nacre, strip protective coatings, or loosen glue in settings. Wipe pearls after each wear, allow them to air if damp, and only store them when fully dry in a soft, breathable pouch or a separate compartment to prevent contact with harder metals or gemstones. Keep a simple record of condition and any cleaning or restringing, and inspect threads periodically so you can spot progressive wear before it causes loss or damage.

Store pearls in soft pouches and separate compartments
Pearls are soft, with a Mohs hardness around 2.5 to 4, so they scratch easily when they contact harder gemstones or metal; store each pearl piece in its own soft, lint-free pouch of natural fibre, such as cotton or silk, and wrap gently without tight folds to minimise surface abrasion. Use a compartmentalised jewellery box with padded dividers so items do not jostle, and lay pearl necklaces flat in individual slots rather than hanging them, because tension from hanging or tight coiling can stretch the silk or nylon thread and increase friction between beads. Choose breathable pouches and a cool, dark storage location to reduce chemical exposure and light-related fading.
Avoid airtight plastic bags or containers, because pearls are organic and trapped volatile chemicals from plastics can cause discolouration or dulling of the nacre. Keep pearls physically separated from metal jewellery, particularly oxidising metals, since tarnish or silver sulphide can transfer onto the nacre and leave persistent stains; if you must store near metal, place a soft fabric barrier between items and clean any tarnished metal first. Wipe pearls with a soft, dry cloth after wear to remove oils, cosmetics, and perfume that accelerate discolouration, and inspect stored pearls for any sign of staining or loosening knots. Restring or repair weakened threads before wearing to prevent rubbing and bead loss, and follow these simple care steps to help maintain the nacre and strand integrity.

Maintain pearls with humidity control, gentle handling, inspection, and restringing
Store pearls separately in soft, breathable pouches or fabric-lined compartments and lay strands flat to prevent rubbing and stretching, because harder metals and gemstones abrade the nacre and visibly dull the lustre over time. Avoid sealed plastic bags and overly dry locations, since pearls contain organic layers that can dehydrate and craze or discolour when deprived of ambient moisture; instead monitor and maintain moderate humidity rather than creating an airtight environment. If you must mix storage, wrap individual pieces in acid-free tissue or a soft cotton cloth, and place a barrier between pearls and metal clasps or settings to prevent contact that causes scratches and metal transfer.
Put pearls on after applying cosmetics, perfume, and hair products, and remove them before washing or exercising. Wipe pearls with a soft, slightly damp cloth to remove body oils and residues, then allow them to air before storing to reduce chemical damage and discolouration. Inspect stringing and knots for fraying, stretched gaps, or loose clasps, and restring or knot between pearls when signs of wear appear so a single failure does not lead to loss or increased abrasion. Choose a flexible silk or synthetic thread that reduces friction against the beads, and perform regular checks to help preserve their lustre and colour.
Pearls are organic gems whose layered nacre has low Mohs hardness, so it readily acquires micro-scratches and absorbs oils, dyes, and chemicals from metals and cosmetics. Cleaning with a soft, slightly damp, lint-free cloth, drying fully, and storing each piece flat in breathable, soft-lined pouches or compartments reduces abrasion and prevents lasting discolouration.
Recognising why pearls are delicate, preventing abrasion and chemical transfer, cleaning before storage, and monitoring humidity and string condition directly address the risks covered in this guide. Adopt these straightforward routines, and inspect and restring strands when needed so your pearls retain their colour, lustre, and structural integrity.
