Bronze for Cunningham and Cameron
Northern Ireland bowlers Mandy Cunningham and Barbara Cameron won bronze in the women's pairs with a 15-14 victory over Jersey's Katie Nixon and Lindsey Greechan.
In the final, England's Jamie-Lea Winch and Natalie Melmore suffered a 20-17 defeat against South Africa.
England were 16-11 ahead but had to force the game into an extra end, and Tracy-Lee Botha and Colleen Piketh went on to claim gold.
Northern Ireland's medal was only their third so far of the Games, although they are guaranteed nine more in the boxing, and their win in a close match prevented Jersey claiming their first medal in any sport since 1990.
And for Cameron, it was her first medal in five Games.
The 52-year-old Ballymena bowler said: "I've been close to this position on a few occasions but this is it now. It's brilliant, I can't really explain how it feels, it's unbelievable.
"It's a dream come true. You never give up on your dreams."
Cunningham added: "I'm still in shock. I'm absolutely delighted for Barbara. She has said she is bowing out but I think we might try to talk her round."
