Vintage natural Hetian semi translucent jade 14mm bead gold tone necklace

This is an absolutely gorgeous antique/ vintage natural / genuine light green semi translucent Hetian jade 14mm bead necklace. The beads are light green to very faint yellow in color. They measure 13.6 to 14.1 mm in diameter and weigh 127.1 grams. None of the beads are broken, cracked or damaged. Measures 30 inches end to end. I’m not sure of it’s exact age but a similar item online are dated from the 1800 to 1920s. The clasp is made of gold tone metal and has a little metal tarnish that comes with its age. The beads themselves are in excellent condition.
