Oprah Winfrey once bought 10-Carat Diamond Earrings because of Diana Ross' performance at a Central Park concert in 1983. She was inspired by her admiration for her diamond earrings and continued singing through torrential rain. Winfrey called Ross' production company the following day to inquire about the size of the earrings, believing they were five carats. However, she later learned that the information was incorrect and could have led to her quitting halfway through. She also identified Sidney Poitier's 1964 Academy Award win as another formative moment.
