A waterproof AAA zircon tennis necklace — one unbroken line of hand-set stones that catches light from every angle. This is the piece that makes a plain black dress look expensive and a white tee look deliberate.

Made from 18K gold-plated stainless steel with PVD plating and AAA-grade cubic zirconia in a secure channel setting. Fully waterproof, tarnish-free and hypoallergenic — safe for sensitive skin, with no green marks and no fading, so you can shower, swim and sleep in it without a second thought.

Available in gold and silver across four stone widths. 2mm is the delicate everyday layering width; 3mm is the safest all-rounder if you're buying your first tennis necklace; 4mm and 5mm read red-carpet and photograph beautifully. Each weighs around 35 g and fastens with a box clasp plus a safety catch, so it stays put.

Arrives gift-ready in an Ezra Gems pouch. Wear it with the matching AAA Zircon Tennis Bracelet in the same width and metal for a full tennis set, or shop more in our Necklaces collection.

Is this tennis necklace waterproof?

Yes. It is 18K gold-plated stainless steel with PVD plating, so it is fully waterproof. Showering, swimming and sweating will not damage it.

Will a zircon tennis necklace tarnish or turn my skin green?

No. Stainless steel with PVD plating is tarnish-free and hypoallergenic, so there are no green marks and no fading, even with daily wear on sensitive skin.

What width tennis necklace should I choose?

Choose 2mm for delicate everyday layering, 3mm as the most versatile all-round width, and 4mm or 5mm for a bolder, more visible statement.

What is a tennis necklace?

A tennis necklace is a continuous strand of identically sized stones set in a flexible line, so the sparkle runs evenly all the way around rather than sitting in a single pendant.

Can I wear a tennis necklace and tennis bracelet together?

Yes. Our matching tennis bracelet uses the same AAA zircon stones and the same 2mm–5mm widths, so a necklace and bracelet in the same width and metal read as a deliberate matched set.
