A diamond tennis necklace is a continuous line of individually set diamonds running the full circumference of the necklace. It is one of the most luxurious and impressive pieces in fine jewellery. This guide covers everything about choosing, wearing and caring for a diamond tennis necklace.
A diamond tennis necklace is a flexible necklace in which every link contains a diamond, creating a continuous line of sparkling stones around the neck. The stones are typically individually set in small prong or bezel settings, connected by flexible metal links, creating a necklace that drapes softly and moves fluidly.
The name "tennis necklace" comes from a famous incident at the 1987 US Open, when tennis player Chris Evert's diamond bracelet (then called a line bracelet) snapped and fell during play. She asked the officials to pause the match while she searched for it. The story became famous and the style became known as the "tennis bracelet" — and by extension the "tennis necklace".
A diamond tennis necklace is the most diamond-intensive and most impressive single piece of fine jewellery available. A 5.00ct total weight tennis necklace contains dozens of individual diamonds, each set individually, creating a continuous line of brilliance around the neck.
Tennis necklace size is described in total carat weight — the combined weight of all the diamonds in the necklace. The individual stone size is also specified — smaller stones create a finer, more delicate look; larger stones create a bolder statement.
