Vintage long chain necklace with decorative rocks

The chain is 40” circumference with dripping rocks The three 2”iridescent rocks are attached from a 4” decorative ring There is also one small rock and two interesting 1 1/4” wood strips This hard to describe! Very creative. A very nice chain, tied in six random knots With six clusters of three, dark brown in the middle with gold beads on both sides Included are earrings that I wore with this necklace, rocks are 1 1/2” long Excellent condition, from 1970 Hippie days!
