Turquoise colored stone bead necklace

I used to go to estate sales and collected quite a bit of vintage jewelry, always meaning to go thru and sell it. I don’t have the time to research each piece so I decided to just post lots on here and try to clear this box out. This is a pretty turquoise colored necklace. I believe the beads are made of stone and the silver beads in between are tarnished which leads me to believe they may be silver or silver coated. Has a good weight to it. Very pretty necklace
