Seventeen-year-old Andrea Spendolini-Sirieix shrugged off the pressure to nail her final dive and seize European 10m platform gold for Great Britain.
Commonwealth champion Spendolini-Sirieix trailed Ukraine’s Sofiia Lyskun by two and a half points after the fourth and penultimate round in Rome.
But Spendolini-Sirieix, daughter of TV personality Fred Sirieix, scored 76.80 for her final attempt to win.
Earlier, Britain’s Grace Reid and James Heatly won synchro springboard silver.
The Edinburgh duo, who won Commonwealth gold in Birmingham earlier this month, were edged out by polished German pair Lou Massenberg and Tina Punzel.
Reid and Heatly finished on 290.76, nearly four points off the winners.
Italy’s defending champions Matteo Santoro and Chiara Pellacani led after two rounds, but a scrappy third set of dives saw them slip down the standings.
The home-crowd favourites secured bronze by only 0.06 points from strong-finishing Swedish pair Emilia Nilsson Garip and Elias Petersen.
Spendolini-Sirieix’s focus pays off
Spendolini-Sirieix’s success means Great Britain top the diving medal table with two golds, a silver and a bronze from the championships so far.
Spendolini-Sirieix and partner Noah Williams opted to miss the mixed 10m synchronised event to focus on individual events after a demanding summer.
It paid off for both Spendolini-Sirieix and the team with compatriots Kyle Kothari and Lois Toulson winning the European title in her and Williams’ absence on Tuesday, before she swept to victory with a polished final dive.
Spendolini-Sirieix was only fifth best after an untidy entry into the water on her first dive.
Lyskun, who won the title in Kyiv in 2019, opened up a 12-and-a-half-point overall lead on her British rival after the second dive.
But Spendolini-Sirieix gradually reeled her in and landed a highly technical back dive with two and a half somersaults and one and a half twists in a pike position to take victory.
The Briton finished on a total of 333.60, bettering Lyskun’s 329.80.
Team-mate Toulson climbed up the standings to sixth after a disappointing first dive.
