Vintage Crystal Necklace Two Strand Red Clear AB Graduating

Offered is a fascinating vintage crystal necklace.  It is composed of both red and clear glass crystals with an aurora borealis finish. There are round filigree elements with a dark antique finish that feature a band of inset rhinestones as well.   The faceted round and bi cone beads graduate in size from the front to the back of the necklace strands.  For reference, the largest bi cone is 5/8″ from end to end, and the smallest is 1/4″.  The wearable length of this choker style piece is determined by the shortest of the two strands.  That is 15 3/4″ including the extender portion.  The bottom strand is a bit longer and provides an additional drop. The jewelry is old, but in good condition with no damage to report.
