Vintage 60’s space-age-y unusual charm bracelet.

This is an unusual charm bracelet with clear lucite charms, and unusual round ball charms that I do not know composition of. I believe the bracelet is from 60’s or early 70’s but not positive. It’s just a fun one to pull out every now and then regardless of age. The darker color on the ball shapes is sort of a silver green. See measurements in pictures. Unmarked.
