Art Deco Mint Green Glass Bead Necklace

Absolutely beautiful hand blown glass mint green beads on this necklace from the art deco era 1920s/30s. Each bead is hand knotted in between and there is a brass hook closure. There is something written on the inside of the hook but it is very hard to make out. My guess is Made in Italy but I am unsure. Good vintage condition. Even though the beads are nice and heavy, the strand feels totally secure and ready for wear even after all these years.
