Definition: A tennis bracelet is a flexible bracelet with diamonds (usually of the same size) set closely together, one after the other, all the way around its circumference. Although the term usually refers to diamond bracelets, you'll see colored gemstone versions tagged with the same name.
I haven't been able to confirm the term's origin, but it's reported that former pro tennis player Chris Evert regularly wore this bracelet style, and even stopped a game to find a bracelet that fell off during a match, leading to the jewelry's popularity and its name.
