A tennis bracelet is a type of jewelry consisting of a thin, flexible band of precious metal (like gold, platinum, or sterling silver) adorned with a continuous row of diamonds or other gemstones. The design is sleek and elegant, making it suitable for both casual and formal occasions. The name "tennis bracelet" originated from an incident in the 1987 U.S. Open when tennis player Chris Evert's diamond bracelet fell off during a match, and the event was widely publicized.
