Werth and fiery chestnut mare Bella Rose came out as the last rider of 30, presenting a flawless test. The pair scored 86.246%, including several 10's from the judges' panel of seven.
"Three were out with more than 80 already so I knew we had to give it our best. When Bella started to trot I felt she wanted to go and do it and the half passes could not have been better," said Werth.
Graves had put everything into her ride, presenting the 16-year-old Verdades with utmost precision in each step, despite gusts of wind picking up during her ride.
"It feels amazing. Two days in a row we really delivered for our country. The heat is a test of a horses' character." Equally sensational was Charlotte Dujardin's ride to Bronze, piloting her mare Mount St John Freestyle to 81.489%. The nine-year young mare showed picture-perfect passage that is usually only acquired at a more advanced age.
"Her passage was incredible. We continue to work on it and will give Isabell a run for her money." Germany's Sönke Rothenberger missed the podium by 0.44 points after mistakes in the one-tempi changes.
"I am disappointed. The horse would have deserved a medal because of its overall quality, but of course, we should not make mistakes."
