A buyer in Stockholm ordered a 17 cm tennis bracelet with 3.0 mm round moissanite, sixty-one stones. Within eight weeks three links had opened and the bracelet kinked when worn. The clasp was fine. The problem was the link gauge: each link was set too thin for the stone weight, and the chain stretched under the pull of the stones. Tennis bracelets look simple, but the lie-flat and the no-break record come from three numbers we lock before we cut any wire.
If you are pairing a bracelet with a ring set, our wedding band matching guide covers the same measurement discipline. Below is how we build the bracelet itself.
Stone count and spacing for a flat lie
A 17 cm wrist wears a row of 3.0 mm stones across roughly 15.5 cm of usable chain. At 3.2 mm centre-to-centre spacing that is about forty-eight stones, not sixty-one. Overcrowding the links forces each setting to press against the next, and the bracelet arches instead of lying flat. We space stones at 1.06 times the stone diameter so each seat has wall between settings. The result is a bracelet that hugs the wrist without doming. The even light-play that spacing produces is the difference between a cheap look and an heirloom look.
Link gauge sized to stone weight
Each stone setting hangs from a small jump ring that carries the full pull of the bracelet. On a 3.0 mm stone we use a 0.9 mm wire gauge for the links; on a 4.0 mm stone we step up to 1.1 mm. Undersized links stretch and open, which was the Stockholm failure. Oversized links read bulky and catch on cuffs. We record the link gauge on the order sheet so QC rejects any link that falls under spec. The metal alloy we draw the wire from is held to the stamped purity, following the karat convention on Wikipedia's karat reference.
Clasp sizing and safety catches
A tennis bracelet needs a box clasp with a figure-8 safety, not a spring ring. Spring rings open under the lateral pull a bracelet takes on the wrist, and that is the second most common reason bracelets come back. We build the clasp to 4 mm wide, flush with the stone row, and we test it for snap closed three times before QC passes it. On bracelets sold to clients who wear them daily, we add a second safety latch at no extra cost because the warranty cost of a lost bracelet far exceeds the clasp cost. For the matching necklace side of a jewellery set, see our pendant and chain choice guide.
Length, sizing and the extender
Wrist sizing on tennis bracelets is unforgiving: a 1 cm too-big bracelet flops and twists, a 1 cm too-small one pinches when the hand swells. We size to the wrist measurement plus 1 cm of movement, and we offer a 2 cm extender chain on orders under 16 cm. Because moissanite is a flat per-stone cost, we can offer half-size lengths without the cost jump a diamond bracelet faces, which is a real talking point at the retail counter. The finished piece ships with the documentation covered in our appraisal and valuation reporting guide.
What stone size sells best for a tennis bracelet?
3.0 mm round is the default mover: enough sparkle to read, light enough to wear daily. 4.0 mm is the statement build and sells to a smaller client group.
How long should a tennis bracelet be?
Wrist measurement plus 1 cm of movement. Size tight and it pinches; size loose and it twists. We build half-sizes to hit this exactly.
Why do tennis bracelets break at the clasp?
Usually a spring ring used where a box clasp belongs. We default to a box clasp with figure-8 safety, and a second latch on daily-wear pieces.
Can tennis bracelets be resized?
Yes, by adding or removing a link, which costs far less than resizing a ring. We build spare links into the first order so the retailer can size it in store.
Why round stones beat fancy cuts on a bracelet
Oval and pear stones read dramatic on a pendant, but on a tennis bracelet they catch and rotate because each link turns independently. Round moissanite sits in its seat evenly and stays flat on the wrist. We stock round as the default and build fancy-cut bracelets only to order, because the round bracelet survives daily wear with far fewer returns. The even light-play round spacing produces is the reason the classic bracelet never goes out of style.
Send us the wrist range you sell to and the stone size. We return the stone count, link gauge and clasp spec on the build sheet before we cut wire. Ask us to quote your next custom moissanite tennis bracelet.
Frequently Asked Questions
Is moissanite a good diamond alternative for retail buyers?
Yes for price-sensitive customers who want brilliance and hardness. Moissanite ranks 9.25 on the Mohs scale, holds up to daily wear and costs a fraction of a natural diamond of the same size, so it resells fast in bridal and fashion lines.
What is the minimum order for wholesale moissanite?
MOQ starts at 50 pieces per design for stock items. Custom cuts and private-label settings usually start at 100–300 pieces depending on the mold.
Do you provide certificates with moissanite stones?
Yes. Every parcel ships with GRA or IGI documentation listing carat weight, color grade and cut. We recommend passing the certificate to your end customer for trust.
How long does sample and bulk production take?
Samples ship in 3–5 days. Bulk runs take 15–20 days under 500 pieces, and 25–30 days for custom work.
