Vintage Signed Laguna Clear And Red Beaded Necklace

Vintage 50s-60s-70s, Beautiful Condition, signed Laguna on the hook clasp. Last picture shows the knotted string at both ends of the necklace. This string was used for the main part of the necklace which is clear beads separated by tiny red beads. The extension is clear beads only (no red), and they are strung on metal to hook the clasp. I do not know what the beads are made of. Please see all pictures and video to aid in description and for signs of age. Really pretty how the light shines off the clear beads like crystal due to many cuts around each bead. Overhead light on for pic #3 and video, natural lighting used for all other pictures, no filters used.
