Vintage Art Deco Carnelian gemstone orange & clear glass OR rock crystal faceted bead hand knotted flapper necklace - 1920s, long and heavy

Very long vintage alternating Carnelian gemstone and clear glass or rock crystal faceted bead necklace, hand knotted on pale creamy orange thread. The heavy beads are graduated in size.

This is a long 1920s flapper length (40 inches); it can be doubled up over the head despite no clasp being present. I've also shown it as a single strand or knotted in the photographs.

The necklace is in very good vintage condition.
