Gorgeous amethyst colored open-backed rhinestones are collet set in a gold tone setting and linked by chain.  The setting is engraved on the reverse side and is so pretty that you may choose to wear it with the back side showing.  These pale violet stones sparkle very brightly in this simple setting that allows the stones to have your full attention.  Necklaces such as these are found from the 1925 Deco era throughout the 1940s and 50s.  The hook clasp indicates that this set of stones is from the latter period.  They measure 10mm with some smaller stones near the clasp.  The entire choker is 15 1/2" including the section of stones that attaches to the adjustable clasp.  SORRY. THIS ITEM HAS ALREADY BEEN SOLD!
