A retailer in Vancouver ordered thirty tennis bracelets with 3.0 mm round moissanite, four prongs per stone. On half the batch, stones sat unevenly after two months of wear. The cause was not the prongs. The cause was link length tolerance: adjacent links were stamped to plus or minus 0.15 mm instead of plus or minus 0.05 mm, so the bracelet twisted and the stones tipped.
Tennis bracelets are a chain of identically set stones, and the chain tolerance is what fails. Below are the link, clasp and sizing specs we hold on every tennis order.
Stone size and carat per row
We build tennis bracelets in 2.0, 3.0 and 4.0 mm round moissanite. A 3.0 mm stone weighs about 0.11 carat; a 7 inch bracelet with 21 stones runs about 2.3 carats total. The 3.0 mm row is our volume seller at roughly 65 percent of tennis orders. The 4.0 mm row sells to evening wear and the 2.0 mm row sells as a stacked bracelet. Buyers stock one 3.0 mm row in sterling silver and one in 14K white gold to cover most retail requests.
Link spacing and prong count
Each stone sits in its own link, linked to the next by a figure-eight connector. We hold link length to plus or minus 0.05 mm so the bracelet lays flat. The connector is 0.8 mm wire; below that, the bracelet kinks under wrist rotation. We use four prongs on 3.0 mm stones and six prongs on 4.0 mm stones, because four prongs on a 4 mm stone leave the tips catching on knitwear. Our tennis bracelet design guide lists the prong count per stone size we build.
Clasp: lobster, box and figure-eight safety
Box clasps are the default on tennis bracelets; they lay flat and lock with a tab. Lobster clasps are cheaper but sit proud of the wrist. We add a figure-eight safety chain to every box clasp at no extra charge, because the clasp is the single point of failure on a tennis bracelet. The safety chain runs 0.6 mm wire and prevents the bracelet from falling off if the tab opens. We have seen return rates drop from 4 percent to under 1 percent since we made the safety chain standard.
Length sizing and extension chain
We stock 7.0 and 7.5 inch bracelets as standard. A 1 inch extension chain adds USD 0.90 per piece and lets the bracelet fit a 6.5 to 8 inch wrist. Buyers should not size a tennis bracelet tight: a bracelet that leaves a mark on the wrist comes back for re-sizing within a month. We recommend a 0.5 inch gap between the bracelet and the wrist bone. Our tennis link build notes cover the connector and sizing tolerance.
Rhodium and plating wear
Sterling silver tennis bracelets are rhodium plated at 0.3 microns. The plating wears through at the clasp and on the top row of stones after about 12 months of daily wear, which is normal. We quote a re-plating service at USD 12 per piece. White gold bracelets are plated to the same thickness; we test each batch against the karat fineness markings so the stamp matches the alloy we cast. Buyers should also read our sterling versus 10K gold guide before quoting a tennis line.
Packaging and retail display
Tennis bracelets ship flat in a padded tray, not coiled, because coiling kinks the links. We pack each bracelet in its own 8 x 8 cm box with a foam insert that holds the clasp open. Retailers tell us the flat pack cuts display setup time by about half compared with coiled stock. We also include a 1 inch care card that lists the re-plating cycle and the clasp check. Buyers ordering above 50 pieces get a branded insert printed at no extra charge.

What carat per row sells best?
The 3.0 mm row at about 2.3 carats total on a 7 inch bracelet. It reads as a tennis bracelet without tipping the wrist, and it sits in the middle of the retail price band.
Do you use four prongs or six on a 3 mm stone?
Four prongs on a 3.0 mm stone, six prongs on a 4.0 mm stone. Below 3 mm, four prongs leave too much wire on the crown and reduce light return.
How long should the extension chain be?
1 inch, on a figure-eight safety. It covers a 6.5 to 8 inch wrist, which is about 90 percent of the female adult wrist size we measure.
Can tennis bracelets be resized?
Yes, by adding or removing links. We charge USD 4 per link and require the original clasp to come back. Re-sizing changes the carat count on the row, so we update the spec sheet.
Send us the stone size, wrist size and metal. We return a link gauge, clasp and extension spec on the sheet before production. Ask us to spec your next 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.
