Malaysia's Cheong Jun Hoong stunned Chinese rivals Si Yajie and Ren Qian to claim the women's 10 metres platform diving title at the International Swimming Federation (FINA) World Championships in Budapest today.
It follows the bronze medal she won earlier in the week in the 10m platform synchronised event in the Danube Arena alongside Pandelela Rinong.
The duo had also claimed silver behind China at the Rio Olympic Games.
But this marks by far the biggest achievement of Cheong's individual career.
The 27-year-old took the lead in the third round before holding her nerve for a total score of 397.50.
Olympic silver medallist Si scored 396.00 for silver while Ren, winner of the gold medal in Rio de Janeiro, was third with 391.25.
United States' Ashley Twichell secured victory in the women's five kilometres open water event elsewhere today in Lake Balaton.
She triumphed in 59min 07.00sec to defeat 10km winner Aurelie Muller of France by 3.50.
Brazil's Ana Marcela Cunha finished a further 0.90 behind in third.
Russia's Svetlana Kolesnichenko claimed the day's other gold medal in the women's solo synchronised swimming final.
It marked the 12th world title of the 23-year-old Olympic team champion's illustrious career.
She scored 96.1333 to beat Spain's Ona Carbonell, who posted 95.0333 for second place, and Ukraine's Anna Voloshyna, who managed 93.3000 for third.
