Why is the Tennis Bracelet called this way?

Tennis is a remarkable type of jewel, a timeless classic that mixes elegance, comfort and sportiveness.
During a crucial match of the US Open, the famous Chris Evert suspended the match when she lost a precious diamond bracelet because of a sudden arm movement, and the match remained suspended until It was found again. From that day onward that specific kind of bracelet was called “tennis”.
Its unique characteristic consists in being a soft bracelet with precious gems mounted in silver or gold setting. Its composition reminds a never-ending string of diamonds that symbolizes eternity. In fact, before 1987 the tennis bracelet was called Eternity.
The OMG, the Italian Jewelry Market Observatory, did a survey on a 1000 people sample between 30 and 60 years old, and 63% of these people declared they chose the Tennis Bracelet over colliers, rings and earrings. This Bracelet has made the history of the jewelry industry.
