A buyer in Denver ordered a 7-inch tennis bracelet, sold it to a client, and got a call a month later: the clasp had opened during a tennis match and the bracelet was gone. The stones were fine; the figure-eight safety was the weak point. That complaint is the reason we now spec every moissanite bracelet - tennis or link - around the clasp first and the stones second. Below is the build spec we use on custom bracelet orders, whether the buyer wants a single-row tennis line or a station link piece.
Tennis bracelet construction and stone count
A tennis bracelet is a single row of stones, each in its own head, linked by articulated segments. The stone count for a 7-inch (17.8 cm) bracelet is roughly:
- 3.0 mm round: about 46 to 50 stones per row.
- 4.0 mm round: about 34 to 38 stones.
- 5.0 mm round: about 26 to 30 stones.
Each stone sits in a 4-prong head, and the links between heads must articulate enough to lie flat on the wrist. We spec the link to move through 25 degrees of flexion so the bracelet does not kink. The prong vs bezel guide explains why we use prong rather than bezel on a tennis row - light return matters more here than edge protection.
For the stone itself, moissanite's optical reference is GIA's cut-quality framework; we grade our tennis-row stones for match in size and color within each parcel.
Link-style bracelets with moissanite stations
A link bracelet is a chain (Figaro, cable or curb) with moissanite stations set at intervals. We spec stations every 2.5 to 3.5 cm, with 4 to 6 stations on a 7.5-inch bracelet. Each station is typically a 4 to 5 mm round in a bezel, or a 3-stone cluster. Link bracelets are lighter than a full tennis row, retail at a lower price point, and are the entry-level line for buyers who want a moissanite line without the tennis-bracelet price. The chain gauge guide covers the link stiffness math.
Clasp and safety choices
This is where tennis bracelets fail. We ship three clasp options:
- Box clasp with figure-8 safety - standard, but the figure-8 can open under shear. We use this on link bracelets only.
- Box clasp with double safety latches - our default for tennis bracelets; two independent latches must release.
- Hidden tongue clasp with safety chain - for high-end pieces; the safety chain is a backup if the main clasp opens.
We also spec that the clasp segment is slightly stiffer than the rest of the row, so the bracelet does not bend at the clasp - that bending is what pries the latch open. Our QC checklist includes a clasp pull-test at 2 kg before shipment.
Length and wrist sizing
Retail women's bracelets run 7.0 to 7.5 inches (17.8 to 19 cm). We build to the wrist measurement plus 1.0 to 1.5 cm so the bracelet slides on and off without falling over the hand. Men's link bracelets run 8.0 to 8.5 inches. At MOQ 5 units we offer half-inch steps so the buyer can hold stock. For matching earring orders, our earring findings guide covers pair-matching and nickel-compliance specs.
Weight, nickel contact and daily wear
A 4 mm stone tennis bracelet in 925 sterling weighs roughly 12 to 15 g; in 14K gold it runs 18 to 22 g. The weight is what makes a tennis bracelet feel premium on the wrist, but it also drives the price. For EU-bound pieces we spec nickel-free alloys and reference the REACH nickel-release limit, because a bracelet sits on the skin for hours each day. Link bracelets run lighter - a 7.5-inch link with four stations weighs 6 to 9 g in sterling - and are the piece buyers position as an entry-level everyday line. We recommend buyers keep at least one extension chain on file so a client who loses or gains a few millimeters can size the bracelet without a workshop trip.
How many stones in a 7-inch tennis bracelet?
About 48 at 3.0 mm, 36 at 4.0 mm, or 28 at 5.0 mm. The exact count depends on the head width between stones.
What clasp is most secure?
A box clasp with double safety latches. We use it on every tennis bracelet by default; figure-8 safety is reserved for lighter link bracelets.
Can you mix stone shapes on a tennis row?
Yes, but we keep shapes in segments - for example, a 4 mm round row with two 5 mm emerald-cut stations. Mixed shapes on the entire row read unevenly.
What bracelet length do women order most?
7.25 inches (18.4 cm) is the most common. We hold half-inch steps at MOQ 5 so buyers can size clients in store.
Do you offer men's link bracelets?
Yes. A 10 mm curb link with 5 mm moissanite stations at 3 to 4 points is a common men's order. Length runs 8.0 to 8.5 inches.

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.
