China's Ren Qian won the women's 10 metre platform competition a day after her 15th birthday as more Olympic berths were claimed at the International Swimming Federation (FINA) Diving World Cup in Rio de Janeiro.
Qian, the World Championships silver medallist, dominated the event, which is serving as a tester for the Olympics in Rio in August.
She claimed a perfect ten points with her final dive at the Maria Lenk Aquatics Stadium, executing perfectly a back two and a half somersault and a half twist to finish with 454.6 points and the gold medal.
"I only did my best and what I do in my training," she said.
"My first 10 was last year.
"I’m not feeling pressure because of the Olympics because we will have other competitions until then, so I think that it’s necessary to think of a competition at a time."
China also finished second as Si Yajie totalled 412.80 points, with Australia's Melissa Wu taking bronze with 380.50.
All three divers had already claimed their Rio spots, with a number of competitors doing enough with their ranking to book berths for their country.
Maria Kurjo did enough for Germany by finishing seventh, while Britain's Georgia Ward and Japan's Minami Itahoshi also earned quota places by coming eighth and ninth respectively.
Samantha Bromberg of the United States earned her country a place by coming 12th.
China also won the other event contested, the men's synchronised 10m platform, as Yue Lin and Aisen Chen registered 456.00.
The gold medallists from Beijing 2008 had to battle weather conditions at the open air venue, which saw rain and lightning postpone competition for 40 minutes.
The podium was completed by Germany with Patrick Hausding and Sacha Klein scoring 448.44, and Great Britain who registered 446, 40 thanks to Tom Daley and Daniel Goodfellow.
With China already qualified, both European countries earned Rio spots along with fourth placed Americans David Boudia and Steele Johnson.
Ukraine's Maksym Dolgov and Oleksandr Gorshkovozovo also qualified after a sixth-place finish.
The action continues tomorrow with men's and women’s 3m springboard events.
