Lab-Grown Diamond Tennis Necklace
A tennis necklace is a single unbroken line of diamonds circling the neck — the necklace sibling of the bracelet Chris Evert made famous at the 1987 US Open. Because a diamond tennis necklace carries several carats at once, this is where lab-grown pricing saves the most in absolute dollars: our 14 designs run from $2,275 to $26,915, where mined equivalents can cost several times more.
Choosing your tennis necklace
Total carat weight and length set the look — a lab grown diamond tennis necklace in white gold reads classically icy, while yellow gold warms every stone. The style is genuinely unisex: the mens tennis necklace has become one of the defining pieces of current men's jewellery. Match yours with a tennis bracelet for the full line.
Why lab-grown wins biggest here
Multiply the per-carat saving across an entire strand and the gap becomes enormous — every stone IGI-certified and matched to its neighbours for colour and clarity, as the style demands.

Sizing a diamond tennis necklace
Budget planning starts with stone size, because it compounds: at a 16-inch length, 2mm stones total roughly 5 carats, 2.5mm about 8, and 3mm pushes past 11 — small diameter changes move total weight dramatically. Decide the look first (delicate line versus statement row), then let length fine-tune it: 16 inches sits at the collarbone, 18 drops just below, 20 reads relaxed.
Two checks before any purchase, anywhere: the clasp should be a box or lobster closure with a safety figure-eight — this is jewellery that carries real weight — and the links should flex freely in every direction so the line hugs the collarbone instead of standing away from it. Stiff links are the tell of a cheaply made piece regardless of the stones.
Tennis necklace FAQs
Why is it called a tennis necklace?
The name comes from tennis star Chris Evert, whose diamond line bracelet snapped during a 1987 US Open match — play stopped to find it, the press named the style, and the necklace inherited the name.
What is a graduated tennis necklace?
A graduated tennis necklace tapers its stones — largest at the centre, smaller toward the clasp — concentrating carat weight where it shows most.
How many carats is a tennis necklace?
Anywhere from around 5 to 20+ total carats depending on stone size and length — which is why a lab grown tennis necklace costs a fraction of its mined twin: the saving multiplies across every stone.
Can men wear a tennis necklace?
Absolutely — the diamond tennis necklace men's trend is one of the strongest in current jewellery, usually in slightly larger stones and shorter lengths.
What length should I choose?
16–18 inches sits at or just below the collarbone — the classic drop for a tennis necklace womens buyers choose most; 20+ inches reads more relaxed and unisex.
Which gold suits a tennis necklace?
A gold tennis necklace in yellow warms the line and reads vintage; white gold disappears behind the stones for a pure-diamond look — the most popular choice.
