Tennis bracelets and necklaces got their unusual name from an incident involving the U.S. professional tennis player Chris Evert during a tennis match in the 1980's. Evert had been wearing an expensive diamond bracelet, an inline string of individually-set diamonds. Previously these bracelets were known as eternity bracelets. When the clasp snapped during play, she asked the officials to stop the tennis match until the bracelet could be found. Since that day, bracelets and necklaces featuring an inline string of diamonds have been called tennis bracelets and tennis necklaces.
