CZ tennis necklaces: a buyer's guide

A CZ tennis necklace gives you the unbroken, light-catching line of a classic diamond tennis necklace at a fraction of the cost — buy on stone quality, setting security and an honest base metal.

The quick version

• A tennis necklace is defined by its continuous, unbroken line of individually set stones — no pendant, no gaps. CZ delivers that look honestly; it isn’t a diamond and we never pretend it is.
• What matters most is setting security + stone cut. Well-cut AAA cubic zirconia (Mohs ~8.5) throws bright fire; a loose stone in a flimsy setting is the real failure point.
• Be aware that most CZ tennis pieces — including ours — are 18k gold-plated brass, not solid gold, so they need a little care.
