4mm Tennis Chain Necklace — Unisex 5A CZ Everyday Iced Chain

The one size that works for everyone. The 4mm Iced Tennis Chain hits the sweet spot between delicate and statement — wide enough to hold visual weight on its own, slim enough to layer without looking overdone. It reads unisex across all chain lengths and works equally well on a woman's collarbone or a man's chest.

This is the chain most customers reach for first — the everyday go-to that pairs with almost anything in our pendant collection.

Why 5A CZ?
5A cubic zirconia sits at the top of the CZ clarity scale. More facets, higher light return, and less visual cloudiness than standard 3A or 4A stones. At 4mm width you're getting a full row of 5A stones — the difference in sparkle is visible in person.

What's the difference between 3mm and 4mm?
The 3mm chain is our slimmest — built for minimal layering and choker-style wear, skewing feminine. The 4mm adds just enough width to read confidently on a man's neck while still working on women who prefer a slightly bolder chain. If you're buying one tennis chain to do everything, 4mm is the answer.

Perfect for:

• Men and women who want a single versatile iced chain for daily wear
• Pairing with any pendant in our collection — block, gothic, cursive, or varsity styles
• Gym-to-night wear — slim enough to not feel heavy during activity, present enough to elevate an outfit
• Shoppers across the US, UK, Europe, Canada, Australia, and the Middle East looking for an affordable unisex tennis chain with 5A CZ quality
