This is a really great vintage bead necklace of graduated faceted Czech glass beads in clear and deep opaque jade green. The center section of the beads are strung on a fine chain. The rest of the beads are wired. While all of the clear beads are faceted, only the larger green beads in the center section are. The rest of the green beads are smooth. It fastens with a spring ring catch. Being on wire as it is makes it very secure, so there would be no worries about restringing. It is marked on the jump ring and I believe it reads Czechoslov however it is very tiny and the stamp is blurred.
It measures 17 1/2 inches long and it is in excellent condition. There is some light wear but no significant issues.
