Daley has his sights set on success at the 2012 Olympics in London
Tom Daley claimed 10m platform silver in a fiercely-contested final at the World Series event in Sheffield.
The 14-year-old Plymouth diver recorded 10s in four of his six dives to score 540.85 - a new personal best.
But it was still not enough to secure gold as China's Liang Huo edged him out by just 0.60 points.
Such was the high quality of the competition at Ponds Forge, Olympic champion Matthew Mitcham of Australia had to settle for fourth place.
"It was a very high standard competition so I'm pretty chuffed," said Daley.
"I was thinking going into that final with two Olympic champions and a World Youth champion that I would be lucky to get a medal, let alone be half a point off a gold.
"It would have been nice to hear the national anthem but we'll have to leave that for London at the 2012 Olympics."
Britain's Ben Swain and Nicholas Robinson-Baker claimed their second bronze medal of this year's World Series in the men's 3m synchro.
They saved their best-scoring dive until last, which lifted them from fourth into the medals.
The pair, who took bronze in the series opener in Doha last month, also recorded their season-best score of 420.75.
The Chinese duo of Qin Kai and Zhang Xinhua took gold with a score of 441.54.
"We keep improving with each meet so we are very happy," said Swain. "The competition is getting better and we're keeping pace with them. We're closing on the Chinese."
Identical twins Helen and Carol Galashan had a mixed day on their World Series debut in the women's platform synchro.
The 21-year-olds have had a quick rise to prominence after only converting to the sport from gymnastics two and a half years ago.
Sunday saw them give an international debut to their unique armstand back double somersault with one-and-a-half twists but they disappointingly failed to land it.
Despite that, they managed a commendable fourth place.
"It was a good experience for us and to get fourth was beyond what we expected," said Helen.
