Han Wang and Qulin Zhang of China took the gold with 305.70 points. Abel, from Laval, Que., and Heymans, from St-Lambert, Que., were second with 303.60.
"It's definitely a very encouraging performance for us to finish so close to the Chinese pair," Abel said. "The score wasn't our best and you have take into account that the judging here this week was very tough.
"We made a small error on our third dive and that may have been the difference."
