Ruth Small added the Commonwealth gold medal to her national title with victory over Zimbabwe's Constance Sibanda in the blind final.
The 51-year-old captured England's third gold medal in the Games with a 15-0 triumph, following the success of the men and women's fours teams.
"I'm still in shock because this is everything that I could have dreamed of," said Small.
"I was a little surprised at how comfortable I managed to win in the end, but I am overwhelmed by it all."
New Zealand's Mike Kernaghan earlier won a controversial men's singles quarter-final 21-17 after Australia's Steve Glasson had his winning bowl taken.
Glasson was penalised for rink possession in the 22nd end after both men had complained to English umpire Mike Roberts of their opponent breaking the rules.
The decisive moment came when Glasson, who had already been warned once over foot faulting, broke the rules again and so had his bowl taken away.
Technical delegate Kerry Clark said: "This had gone on through the game and he (Roberts) warned them both that any further occurrence or infringement would result in action being taken and that is what happened."
Robert Weale guaranteed himself at least a bronze medal with a thrilling victory over Scotland's Darren Burnett.
The Welshman held on for a 21-18 victory after 25 ends to move into the semi-finals.
Northern Ireland's Jeremy Henry also made it into the last four after coming from 6-0 behind in the fifth end to beat Zambian Eddie Nkole 21-11.
But England's Mervyn King saw his hopes disappear with a 21-7 defeat against South African Robert John Donnelly.
In the women's pairs, England's Lynne Whitehead and Amy Gowshall were comprehensivley beaten 23-12 by South Africa's Ellen Cawker and Jill Hacklan.
And Welsh duo Joanna Weale and Anwen Butten also crashed out, suffering a 20-11 defeat to New Zealand's Sharon Sims and Joanna Edwards.
