But the Watford-born 23-year-old had to settle for silver in the clean-and-jerk, which meant she finished second overall.
Breeze, one of only four lifters competing, lifted 87.5kgs with her third attempt to win the snatch from Canada's Maryse Turcotte and India's Sunaina Sunaina.
Breeze, sixth in the 2000 European Championships, entered the clean and jerk with a weight of 107.5kgs and lifted it to break her personal best.
To Breeze's obvious delight, she took her final opportunity to lift 112.5kgs but Turcotte's success at 115kgs meant the 27-year-old took gold and the overall title with Breeze finishing second overall and in the clean and jerk.
Sunaina ended the event with three bronze medals.
India's Sanamacha Chanu took gold ahead of two Australians with a lift of 82.5kg in the women's 53kg snatch competition.
But England's Joanne Calvino endured a miserable time, failing with all three attempts at 62.5kg before leaving the stage in tears.
Three-times Oceania champion Natasha Barker took silver with her fellow Australian Seen Lee taking bronze.
In the clean and jerk, Calvino's first attempt was hindered by the ringing of a mobile phone from the crowd and her humiliation was complete when she was unable to put any scores on the board all afternoon.
Altenor's best was 80kgs and Law accomplished a lift of 77.5kgs but it was Chanu who took gold and the combined crown.
Barker had to settle for three silvers and Lee claimed a trio of bronze medals.
