Pearls are organic and porous — the most delicate material in fine jewelry. The golden rule: wipe with a soft damp cloth after every wear, never use chemicals or ultrasonic cleaners, store separately in a soft pouch, and have strands restrung every 1–2 years. Consistent gentle care is the only thing that preserves nacre long-term.

Quick Answer Daily Cleaning Deep Cleaning What to Never Use Storage Restringing Full Expert GuideQuick Answer: Pearl Care Essentials
- After every wear: Wipe with a soft damp cloth — remove oils, perspiration, and residue before storing
- Deep clean monthly: Soft cloth + lukewarm water + tiny amount of baby shampoo — never submerge strands
- Never use: Ultrasonic cleaners, steam, ammonia, vinegar, baking soda, toothpaste, or chemical jewelry cleaners
- Storage: Soft cloth pouch, laid flat, never airtight — pearls need moisture to prevent cracking
- Restring: Every 1–2 years for frequently worn strands; silk thread with knots between each pearl
- Wear them: Regular wear in moderation helps maintain luster — just wipe after each use
Daily Cleaning: After Every Wear
This is the single most important pearl care habit. Perspiration, skin oils, and cosmetic residue are mildly acidic and will slowly erode nacre if left on the surface.
Microfiber or a dedicated jewelry polishing cloth works best. Never use paper towels or rough fabric.
Work along the surface of each pearl to remove oils, perspiration, and any residue. Do not rub aggressively.
Remove surface moisture before storing.
Storing damp pearls can weaken silk thread and encourage mildew. Never use a hair dryer or heat source to speed drying.
The "Last On, First Off" rule: Always put pearls on after applying makeup, perfume, hairspray, and lotions. Remove them first when you return home.
Deep Cleaning (Monthly or As Needed)
Baby shampoo or a specialized pearl cleaner only. No dish soap, no jewelry cleaner, no degreaser.
The cloth should be barely damp — not wet. Never dip the jewelry directly into water.
Work gently along the surface. For pearl strands, support the strand so it doesn’t stretch.
Remove all soap residue — soap left on pearls can dull the surface over time.
At least 30 minutes. Never submerge pearl strands — water weakens silk thread.
What to Never Use on Pearls
The vibrations can damage nacre and loosen settings. Never use on pearls under any circumstances.
Heat can crack pearls and damage the nacre layer permanently.
All are too harsh for organic gemstones. Will dissolve or etch the nacre surface.
Pearls are calcium carbonate — acid literally dissolves them. Even mild acids cause irreversible damage.
Both are abrasive and will scratch the nacre surface, permanently dulling the luster.
Water weakens silk thread and can cause stretching or breakage. Wipe only — never soak.
How to Store Pearl Jewelry
Store in a soft cloth pouch or lined jewelry box. Lay necklaces flat to prevent thread stretching. Keep in moderate humidity. Store separately from other jewelry to prevent scratching from harder stones and metals.
Airtight containers (pearls need moisture to prevent cracking). Plastic bags (can emit chemicals that damage nacre). Direct sunlight or heat sources. Storing with other jewelry that can scratch the surface.
Pearl Restringing: When and How Often
Restring every 1–2 years. Regular wear puts stress on silk thread and knots.
Restring every 2–3 years. Even infrequent wear causes gradual thread degradation.
Signs restringing is needed: Visible thread between pearls, stretched or discolored thread, loose knots.
Always use a professional jeweler who uses silk thread with a knot between each pearl — this prevents total loss if the strand breaks. DEEVE offers professional restringing services as part of our lifetime warranty commitment. Learn about our warranty →

Complete Expert Guide: Pearl Care & Maintenance
Understanding Pearl Composition and Vulnerability
What Makes Pearls Unique
Pearls are composed primarily of calcium carbonate (aragonite) in crystalline form, along with conchiolin (an organic protein). This organic composition makes them:
- Softer than most gemstones (2.5–4.5 on the Mohs hardness scale)
- Porous and susceptible to absorption of chemicals and oils
- Sensitive to acids, including those in perfumes, cosmetics, and even perspiration
- Vulnerable to dehydration and cracking if stored improperly
Since pearls are often set in 14K or 18K gold settings, it’s important to care for both the pearl and the metal. Learn more in our Complete Guide to Caring for Fine Jewelry.
When to Remove Pearl Jewelry
Always remove pearls before:
- Swimming (chlorine and saltwater damage pearls)
- Exercising (perspiration contains acids that can damage nacre)
- Showering or bathing
- Applying cosmetics, perfumes, or hair products
- Cooking (exposure to heat and food acids)
- Cleaning with household products
- Sleeping
Special Considerations for Different Pearl Types
Freshwater Pearls
Generally more durable than saltwater pearls but still require gentle care following all guidelines above.
Akoya Pearls
Delicate nacre requires extra gentle handling and frequent restringing.
South Sea and Tahitian Pearls
Thicker nacre but still vulnerable to chemicals and acids. Follow all care guidelines meticulously.
Wearing Pearls Regularly
Contrary to popular belief, pearls benefit from regular wear. Natural body oils help maintain luster in moderation, regular wear prevents dehydration from long-term storage, and wearing allows you to monitor condition and catch issues early. However: always wipe pearls after wearing to remove excess oils and acids.
Professional Care and Maintenance
Annual Professional Inspection
Schedule professional inspection at least once a year covering: thread condition assessment, clasp security check, pearl surface examination for damage, setting inspection (for pearl rings and earrings), and professional cleaning if needed.
Restoring Luster to Dull Pearls
If pearls have lost their luster, consult a professional jeweler specializing in pearls. Professional cleaning may restore some luster, but severe damage may be irreversible. Prevention through proper care is always better than restoration.
Travel Care for Pearls
- Use a padded jewelry travel case with separate compartments
- Wrap each piece in soft cloth
- Carry in your carry-on luggage (never checked bags)
- Avoid wearing pearls during travel activities (swimming, hiking, etc.)
- Bring a soft cloth for wiping after wear
Insurance and Documentation
- Obtain professional appraisals for valuable pearl jewelry
- Photograph your pieces from multiple angles
- Keep all certificates of authenticity and purchase receipts
- Consider jewelry insurance for valuable pieces
- Update appraisals every 2–3 years
Signs Your Pearls Need Professional Attention
- Visible thread between pearls in a strand
- Dull or chalky appearance
- Cracks or chips in the nacre
- Loose or damaged clasps
- Discolored or frayed thread
- Loose settings in pearl rings or earrings
