Chain Necklace Lavalier Design Vintage Art Deco Moonstone Onyx

This is a vintage necklace lavalier design - it has an "S" closure and looks and smells like brass chain - we find no marks - beads appear to be moonstone and onyx or other black stone  - quality nice natural beads. Would believe Art Deco but have no provenance from estate.

• Necklace Length approx 21" - Drop length approx 2"
  
• Nice condition from estate - note no flaws - is as arrived from estate, not cleaned polished
  

• Will mail in jewelry box with tissue and pad envelope.
