An August 4, 1987 piece in the Los Angeles Times, marveling about the diamond studs worn by Australian men’s champion Pat Cash said, “And, let’s not forget what Chris Evert did for the diamond ‘tennis bracelet.’” In other words, the name is fully in place by the 1987 U.S. Open. It did not happen at that Slam. If I have to get academic about it, and it seems I do, the 1970s date for the jewel is the one that makes sense historically. It was the disco era when people were beginning to dress down and wear denim with diamonds. There was a desire for low-key luxury and high-end jewelers began making it.
