Vintage Jade bead necklace

This Jade necklace is 19 inches long with a gold tone clasp. The 3rd picture is closest to the true color of the beads. I do not know if the beads are real jade but I have done what test I can do to check like taking the blade of a pair of scissors and try to cut a line in the beads....they would not cut. So I have priced them low because I don't know for sure. They are very beautiful!!! As always I am open to negotiations!
