Vintage Art Deco faceted Carnelian gemstone orange & clear glass crystal faceted bead necklace, strung on foxtail chain

Vintage alternating faceted Carnelian gemstone and clear glass crystal faceted beaded necklace. These are unusual beads and I don't know the necklace's provenance. Beads strung on a slim foxtail chain like this were often made in France by Louis Rousselet. However the screw clasp is not a classic Rousselet clasp and I don't know that this maker ever used real semi-precious gemstone beads like Carnelian. It could equally be a Czech necklace or by another French maker.

The necklace is in very good vintage condition. It has a length of about 17 inches and fastens with a secure screw barrel clasp.
