Are these decorative fruit pieces made from jade?

I took a chance on purchasing these at an estate sale because they look as if they might be jade.  The owner traveled extensively and was also a WWII vet but the estate sale person didn't know where or when they were purchased.  The grape cluster is approx 7 inches long with 5 leaves.  They look remarkably like real green grapes.  The cluster of peaches/plums (?) is about 4.5 inches and the apple is around 3 inches.  Both of these have 5 leaves-one broken leaf on the peaches. There is a light-colored area in the apple but I don't know if it's a flaw in the jade or maybe damage.
