NWT 14 karat (14K ? ) gold filled triangle stud earrings

Brand new gold tone stud earrings. Triangular shape. Good quality. The packaging says 14 karat gold filled. There are no markings on the earrings or on the backs, so not sure if they are really gold filled, or just were sold in the wrong packaging.
