Restringing a Pearl Necklace at Home: The GRIFFIN Guide for Repair

Restringing a pearl necklace at home is well within reach when the pearls are sound and the drill holes are clean. The work asks for the right material, a little patience, and an honest assessment of when to step back. GRIFFIN 100% Natural Silk has been the trade benchmark for pearl knotting since 1866. Born in Carl Schinle's workshop in Schramberg in the heart of Germany's Black Forest, our triple-twisted filament silk is the cord pearl knotters reach for first.

Family-run for 160 years and now in its 5th generation, GRIFFIN is a historic brand founded in 1866 that supplies high-quality Bead Stringing materials and Accessories for jewelry making. This guide covers everything: when home restringing is appropriate, how to size and colour-match the cord, how to release the old thread without harming a single pearl, the eight-step knotting method, and how to finish the work so it lasts.

Can you restring a pearl necklace at home?

Yes, with one condition: the pearls themselves must be in good order, with drill holes that are intact and unchipped. If those two conditions are met, a competent home restring on GRIFFIN 100% Natural Silk produces a result that sits flat against the body, holds its knot pattern, and lasts. The material is the same one a professional jeweller would reach for, and the technique is the same too. What changes with practice is speed and confidence.

The pull-back: if the drill holes show cracking, if the clasp is failing in a way you cannot diagnose, or if the piece is convertible or multi-strand and you are unsure of the original layout, that is the moment to step back and book bench time. There is no prize for forcing a repair on a strand that wants professional help.

A note on cost. Repeat restringing on heirloom pearls is one of the few jewellery tasks where the home cost (a card of GRIFFIN 100% Natural Silk plus a small drop of glue) sits an order of magnitude below the bench rate. For pieces worn regularly, learning the technique pays for itself within the first repair.

What you need: GRIFFIN 100% Natural Silk plus a short tool list

GRIFFIN 100% Natural Silk is the foundation. It is filament silk drawn from the high-quality centre of the cocoon thread, twisted three times for stability and shine, supplied on a 2 m card with a stainless steel beading needle attached. Twenty-one natural colours; thirteen sizes, from No. 0 (≈ 0.30 mm) through to No. 16 (≈ 1.05 mm). The Best of the Best, on the market since 1866.

A short list of other items keeps the bench tidy:

• Knotting tweezers. Bevelled tips that seat a knot tight against the pearl face without fraying the cord. The traditional alternative is a fine awl, but tweezers produce more consistent knots once the wrist learns them.

• GRIFFIN Bead Cord Glue (10 g bottle, item 140105). A clear, flexible, solvent-free adhesive for the two finishing knots at the clasp ends. Applied to the loose knot, given a few seconds to soak into the silk, then pulled tight.

• Small sharp scissors. For trimming cord tails close to the pearl face.

• Flat-nose pliers. For closing the jump ring when the clasp is reattached.

• A grey-flocked bead board or soft cloth. For laying out the pearls in their original graduation while you work.

A note on the pre-attached needle: it is part of the design, not a convenience. Because the needle and the cord are matched at the factory, the needle diameter is correct for the cord, and there is no double-thread guide to navigate. Carded Bead Cord (100% Natural Silk, NylonPower, High Performance) carries this advantage; the spool products (Jewelry Nylon, Braided Nylon Cord) do not.

Matching the original cord size and colour

The right size of GRIFFIN 100% Natural Silk is the largest cord that passes through the pearl drill hole twice with a slight drag. Test two adjacent sizes on one sample pearl before committing to the strand. If the cord slides through unhindered, it is too fine; if it forces, it is too coarse and will wear at the drill-hole edge.

GRIFFIN 100% Natural Silk size chart:

On colour: aim to match the cord tone to the pearl body colour, so the knots read as part of the strand rather than as breaks in it. The full GRIFFIN 100% Natural Silk palette is 21 colours: white, light pink, dark pink, coral, red, garnet, yellow, amber, blue, dark blue, lilac, amethyst, turquoise, jade green, green, olive, cornelian, beige, brown, grey, black. White suits white Akoya and most freshwater pearls; beige suits warm-toned freshwater; yellow suits golden freshwater; black suits Tahitian and dark baroque strands.

Removing the old thread without damaging the pearls

Photograph the necklace flat before cutting anything. The photograph is your record of the graduation order, any colour variation, and the clasp position. If a pearl rolls away, you have a reference.

Work in good light, on a soft surface, with a tray ready to receive each freed pearl in sequence.

For soft, pliable old silk, insert a fine awl or knotting tweezer tip into the side of the knot and worry it open. Approach from the side, never with a direct pull.

For stiff, hardened silk, a single drop of clean water on the knot, then thirty seconds to rehydrate, will usually restore enough flexibility to ease the knot apart. Hardened silk is brittle and unpredictable, and water is gentler than force.

For knots that refuse to release without risk to the pearl, cut. Cut through the silk on the side of the knot away from the pearl. A cut cord is replaced as a matter of course in restringing; a chipped drill hole cannot be undone.

Work from one end, place each pearl on the bead board in order as it comes free, and resist the urge to bunch them. The graduation, if there is one, must come back exactly as it left.

The eight-step pearl-knotting method

This is the GRIFFIN technique for knotted pearl necklaces, refined over more than a century. Follow it in order.

11. String on three pearls and push them to the end of the thread. Secure with slipknots if needed.

12. Tie on an S-Hook Clasp. Form each knot by inserting the knotting tweezers into the loose knot and sliding it tight against the pearl face.

13. Pass the thread back through the first pearl. Push the three pearls along to the clasp and tie the two threads tightly together.

14. Tie the remaining pearls one after another in the same way. Disregard the shorter thread once it is no longer needed.

15. String on all of the pearls one after another, apart from the last three, and tie a knot after each pearl.

16. String on the last three pearls without tying knots. Pass the needle through the jump ring at the second clasp half and back through the last pearl.

17. Push the pearls tight. Tie a knot. Pass the thread through the next pearl and tie another knot. Pass it through the third pearl and tie a third knot.

18. Glue the first and last three knots on the strand with GRIFFIN Bead Cord Glue. Trim the excess cord cleanly.

Two practical notes. First, stretch the cord between both hands before you begin; relaxed silk seats knots more reliably than freshly unwound silk. Second, tighten the cord after each knot is seated, not only at the start; small slackness compounds along a strand of forty or fifty pearls and shows up as gaps between the last pearl and the clasp.

Finishing the work with GRIFFIN Bead Cord Glue

The two finishing knots at the clasp attachments carry the load of the strand every time the clasp is opened. They are the failure points that matter; the knots between pearls are protected by the pearls themselves.

GRIFFIN Bead Cord Glue is the right adhesive for those finishing knots. It is solvent-free, free of softeners, permanent and flexible after drying, and made for textile threads. It is sold in a 10 g bottle with three dosing tips (item 140105). Apply it to the knot while the knot is still loose, give it ten to fifteen seconds to soak into the silk fibres, then pull the knot tight. The bond sits inside the cord, not just on the surface.

For heirloom strands that will see decades of wear, a second knot over the first adds margin. Glue and tighten the first knot; once it has set, form a second overhand knot directly above it; apply a second small drop of glue; pull tight. The added bulk is minimal at the clasp end and the security is meaningful.

A note on glue choice. GRIFFIN sells two adhesives, and they are not interchangeable. GRIFFIN Bead Cord Glue (item 140105) is the right product for silk and nylon cord finishes. GRIFFIN Superglue (item 140103) is the right product for Stretch Magic / Jewelry Elastic Cord knots and for gluing cord bundles inside metal Tube Ends. Use each where it belongs.

When home repair is appropriate, when to send it out

Home repair is the right call when the pearls are intact, the clasp is sound and only needs reattaching, the necklace is a single-strand design of standard length, and the strand can be laid out and photographed before you cut.

Send it to a professional bench when any of these are true: drill holes show cracking, chipping or visible thinning at the entry points; the clasp itself needs replacement (a worn lobster spring, a failing toggle, a magnetic clasp where the casing has cracked); the necklace is multi-strand, convertible, or has integrated graduations across more than one row; the pearls are of significant value and you want independent quality assurance on the repair.

A professional bench is not a defeat. It is a sensible appraisal of which strands deserve the extra eyes.

Care between repairs

Pearls and silk are organic; both respond to environment. A few habits keep the next repair years away rather than months.

Put perfume, hairspray and cosmetics on before the pearls go on. Those products are the main accelerator of silk degradation, and they sit on the cord every time the necklace is lifted into them.

Wipe the pearls and the visible silk with a soft, dry cloth after wearing. Skin oils and perspiration accumulate at the back of the neck where the clasp sits, and that is the spot the cord wears first.

Store flat. Hanging a pearl strand puts constant tension on the two finishing knots at the clasp. A drawer-lined pouch or a soft roll is better than a hook.

Inspect annually. Look at the cord at the back of the strand, where the clasp rides. Discolouration, stiffness or visible thinning at the drill-hole entry points is your cue to restring.

GRIFFIN also makes a dedicated Pearl Caring Cloth that protects the nacre from the airborne contaminants and skin chemistry pearls collect during wear. Use it after each wear. Never apply jewellery cleaning agents to pearls or to silk; use only GRIFFIN cleaning cloths.

Choosing the right cord: silk, NylonPower or High Performance

For a traditional pearl strand, GRIFFIN 100% Natural Silk is the historical and aesthetic choice. The natural shine of silk harmonises with the nacre on the pearl. Knotted strands lie perfectly on the body. The cord is the one the trade has used for more than 160 years.

GRIFFIN NylonPower is the vegan alternative. Same 13 sizes, the carded format with a stainless steel needle attached, and a tensile strength that is double the strength of conventional nylon. NylonPower stretches only 3 to 4 per cent under tension and returns to its original length when released. For customers who avoid animal-derived materials, this is the line.

GRIFFIN High Performance is the strength tier. White only, ten sizes from No. 0 to No. 10, made from high-tech fibres engineered into a dense molecular structure. Necklaces and bracelets that use hard gemstones (rock crystal, amethyst) or heavy metal beads with small drill holes require High Performance, because softer cords will be cut at the drill-hole edge over time.

Most pearl restringing jobs sit with 100% Natural Silk. Save High Performance for the hard-gemstone work it was designed for.

Closing

Restringing pearls at home is craft work in a long tradition. GRIFFIN 100% Natural Silk has been the cord pearl knotters reach for first since 1866, and the step-by-step method that produces a sound, lasting strand has not changed in any significant way during that time. The work rewards a steady hand and an honest eye for what is in front of you. When the pearls and the drill holes are sound, the right cord and a quiet hour produce a strand that lies as it should.

GRIFFIN 100% Natural Silk is available through griffin1866store.com and through authorised GRIFFIN stockists worldwide.

Frequently asked questions

Q. What is the best silk beading thread for pearl restringing?

A. GRIFFIN 100% Natural Silk is the trade benchmark for pearl knotting. It is triple-twisted filament silk on a 2 m card with a stainless steel needle attached, in 13 sizes from No. 0 (≈ 0.30 mm) to No. 16 (≈ 1.05 mm) and 21 natural colours.

Q. Does GRIFFIN sell French Wire (Bouillon) for the clasp ends?

A. Yes. GRIFFIN French Wire is available in three gold-plated and silver-plated variants, matched to thread size: item 401008 (gold) or 402008 (silver) for thread sizes No. 0 to No. 4, with silk also catered for at No. 5; 401010 or 402010 for No. 5 to No. 6; 401012 or 402012 for No. 7, No. 8 and No. 10. French Wire is not required for thread sizes No. 12, No. 14 or No. 16.

Q. What clasp finish should I expect on a GRIFFIN clasp?

A. GRIFFIN clasps and findings are made of 925 sterling silver, nickel-free, with 7-micron 24K gold plating (where applicable). S-Hook Clasps come in three sizes (12.0 mm, 20.0 mm and 30.0 mm). Custom orders are available in rhodium-plated, rose-gold-plated, ruthenium-plated and matt surface finishes.

Q. Can I reuse the original clasp?

A. Often yes. Inspect the spring on a lobster clasp, the latch on a box clasp, or the magnetic seat on a magnetic ball clasp. If the action is firm and even, the clasp is sound. If there is any play, replace it during the restring rather than after.

Q. How long does GRIFFIN 100% Natural Silk last?

A. A correctly restrung strand worn two or three times a week typically holds for two to four years. Occasional wear extends that interval. Silk is organic and degrades through abrasion, hydrolysis and UV; cord at the back of the neck wears first, which is why annual inspection is sensible.
