1950s Silver-tone Bib Necklace with Moonglow Cabochons

This beautiful necklace features four draping snail chains suspended by a triad of moonglow cabochons flanked by round rhinestone set in sculptured setting. The extending chain from the decorative sides has an interesting detail of three semi-round links following by an elongated link pattern. Hook and chain closure terminating with a pear-shaped rhinestone. This piece has a Schiaparelli vibe, albeit I cannot place the chain which looks so familiar to me.
