Fourteen-year-old Si Yajie of China won the women's world 10m platform gold on Thursday with compatriot Chen Ruolin, the previous world and Olympic champion, in second place and Ukraine's Iulia Prokopchuk third.
"I am very excited with this gold," beamed Si.
"Overall, my performance was quite good, especially the first four dives where I was consistent."
Si triumphed with 392.15 points, with defending title-holder Chen, a four-time Olympic champion, who won world gold on Monday in the 10m synchro, fewer than four points adrift on 388.70.
"I am pretty satisfied with my final, except for the fourth dive, which I had only performed once. It went a bit wrong," said Chen.
"The competition is as it is -- someone wins, and someone has to lose. The key is how you manage your failure.
"Having strong opponents in the Chinese team is an additional motivation for me to perform well."
European champion Prokopchuk scooped the bronze on 358.40, more than 30 points behind the Chinese pair.
It was the sixth diving title won by China out of the seven contested so far in Barcelona with only Germany's win by Sascha Klein and Patrick Hausding on Sunday in the men's 10m synchro blotting the copy book.
