Pearl necklaces are typically strung on silk thread with knots between each pearl. Over time, silk weakens — restringing is essential maintenance for daily-wear necklaces.

When to restring

• Daily wear: every 2-3 years
• Weekly wear: every 4-5 years
• Occasional wear: every 5-7 years
• Heirloom storage (rarely worn): every 10 years

Signs restringing is needed

• Silk thread visibly soiled or discolored
• Knots between pearls have loosened
• Pearls roll or click against each other
• Strand stretches noticeably longer than original
• Visible thread fraying near the clasp

Why knot between every pearl?

1. Prevents wear — pearls don't rub against each other
2. Limits damage from breaks — if the silk breaks, only one pearl is lost (not the whole strand)
3. Adds drape — knots create natural spacing and curvature
4. Industry standard — quality strands always feature knot-between-pearl construction

Materials for restringing

• Silk thread — the traditional material; Japanese silk is the gold standard
• Silk-coated nylon — modern alternative, more durable but less flexible
• Beading wire — used only for pearl bracelets and shorter strands; not for necklaces

For premium pearl necklaces (AAA grade, $1,000+), Japanese silk is the standard. Lower-grade work may use coated nylon for cost efficiency.

The restringing process

1. Pearls are removed from old strand
2. Each pearl is inspected and cleaned
3. New silk thread is selected (color matched to pearl base — white for white pearls, dark for Tahitian)
4. Pearls are restrung in original order, with knots between each
5. Clasp is reattached (or replaced if worn)
6. Final inspection and delivery

Cost

Professional restringing typically costs $50-150 for a standard 18-inch strand, depending on pearl count and material. Bracelets: $30-80. Long opera or rope strands: $200-400.

DIY vs professional

We do not recommend DIY restringing for valuable pearls. Professional restringers:

• Use proper tension to avoid stretched or slack silk
• Tie consistent knots between every pearl
• Replace worn clasps with proper findings
• Inspect each pearl for damage during the process

Frequently asked questions

How long does professional restringing take?

5-10 business days typically; faster for simple strands, longer for complex graduated pieces.

Should I clean pearls before restringing?

No — the restringer will clean each pearl during the process. Sending dusty or oily pearls is fine.

Can the clasp be replaced during restringing?

Yes. Worn clasps are routinely replaced. Common upgrades: from base-metal to 18K gold, or from spring-ring to magnetic-safety.

How much does it cost to restring a pearl necklace?

$50-150 for standard 18-inch strands. Pricing depends on pearl count, length, and material (Japanese silk costs more than synthetic).

Can I restring pearls myself?

For practice strands or low-value pearls, yes — quality restringing requires consistent knot tension and proper materials. For valuable pearls, always use a professional.
