Sterling Silver & Prong Paste Rhinstone Bow Choker Necklace

Vintage 1950s sterling silver bow necklace. It is set with rhinestone "paste", but these are the good ones that are set with prongs. Marked "Otis" and sterling in the pendant and the clasp. Measures 14 1/4" long. Weight: 1.2 ounces. Stones are clean and clear. Silver has some tarnish. The clasp works great. 

This necklace came from an estate with another one. They are pictured together in the last two photos.
