The Ferns managed to tie the first quarter 13-13, but slowly gave away too many opportunities, handing the Sunshine Girls a three-point lead by halftime.
It was a battle of the captains in Jamaica's circle as Jhaniele Fowler-Reid and Katrina Grant fought for possession, but it was Fowler-Reid's height advantage that gave Jamaica the upper hand.
Jamaican defender Shamera Sterling, who was named player of the match in their win over Fiji yesterday, was also a tough opponent, leaving shooters Te Paea Selby-Rickit and Bailey Mes little opportunity to land much-needed goals.
The Jamaicans' tight defence in the circle meant Mes was forced to take more long-range shots, and with the absence of injured sharp shooter Maria Folau, the Ferns struggled to close the gap on the scoreboard.
Defender Temalisi Fakahokotau was back on the court in the third quarter, after sitting out their win over Malawi due to a sprained ankle, and her brave and ambitious defensive tactics saw an immediate impact on the court.
However, it wasn't enough to help the Ferns claw back into the clash, as Jamaica held their three-point lead well into the final quarter.
As the Ferns struggled to maintain a consistent flow on court, Jamaica's lead began to soar, opening the tight gap to a handy buffer, which they maintained until the end.
The Silver Ferns will face Fiji tomorrow night before the finals on Saturday afternoon.
