Vintage Amethyst Snake Crystal Pendant Necklace

Vintage 70's or 80's light purple amethyst pendant or charm with silver snake wrapped around the gemstone. Approximately 1.5 inches tall. Small chip in the stone that's about 1/4 of an inch long and is barely noticeable. I only saw it when measuring the pendant and I have had this for a while. Boho bohemian gypsy hippie style.
