A tennis chain is a continuous line of individually set stones, usually all the same size. It is one of the simplest pieces of jewelry to describe and one of the easiest to get wrong. This guide covers the four decisions that matter: stone size (width), length, metal and finish, and the clasp.
Quick answer
- Everyday, subtle: 3mm–4mm width, 18"–20" length.
- Statement or layering anchor: 5mm–6mm width, 20"–22" length.
- Bracelet: 3mm–5mm, wrist measurement plus about 0.5"–1".
1. Width (stone size)
Tennis chain width equals the diameter of each stone. Small changes in millimeters make a big visual difference because the stone's surface area grows with the square of its diameter: a 6mm stone shows roughly four times the face area of a 3mm stone.
| Width | Look | Best for |
|---|---|---|
| 3mm | Fine, delicate line of sparkle | Daily wear, office, layering with pendants |
| 4mm | Clearly visible, still understated | First tennis chain for most people |
| 5mm | Bold | Wearing alone as the main piece |
| 6mm+ | Very bold, heavier | Stage, events, statement stacks |
2. Length
- 16": sits at the base of the neck (choker-like on most men).
- 18": at the collarbone; the most common women's length.
- 20": just below the collarbone; the most common men's length.
- 22"–24": on the chest; useful when layering under a shorter chain or wearing with a pendant.
When layering, keep about 2" between each chain so they do not tangle. See our 3-chain stack guide.
3. Stones, metal and finish
The stone type determines most of the price. Common options are simulated stones, moissanite and lab-grown diamonds; each product page lists exactly which stone is used, along with its color and clarity grade. For a side-by-side comparison, read VVS vs. moissanite.
The base metal is usually 925 sterling silver or solid gold. Silver pieces are often finished with gold plating or vermeil for a yellow, white or rose color; plating wears gradually with friction and chemicals, so care matters (see our care guide).
4. Setting and clasp
- Prong (claw) setting: each stone is held by small metal claws, letting more light in for maximum sparkle. Check that prongs are even and stones sit level.
- Box clasp with safety latch: the standard for tennis chains. A secondary latch adds security against accidental opening.
- Flexibility: a good tennis chain lies flat and drapes smoothly without kinks between links.
Checklist before you buy
- Pick width by how you will wear it (daily vs. statement).
- Measure an existing chain you like to confirm length.
- Confirm stone type, color and clarity on the product page.
- Confirm metal and finish (silver, plated, vermeil or solid gold).
- Check the clasp type and return policy.
FAQ
Can I shower with a tennis chain?
It is best not to. Water, soap and chlorine dull stones and wear plating faster.
Which width is most popular?
For a first tennis chain, 4mm is a common middle ground: noticeable without being heavy.
Do tennis chains come as bracelets too?
Yes. Tennis bracelets follow the same width logic; choose a length about 0.5"–1" longer than your wrist.
