Large antique cameo style pendant on chain.  I believe the metal of the pendant is brass.  The 6 prongs that secure the cameo are split style.  

The cameo is white on a black base.  The metal frame is fancy with open work and an embossed type flower both top and bottom.  

The chain is a tightly woven 16" chain that closes with a flat push in catch that works well.  

It’s an oldie but goodie in nice antique condition.  Cameo frame is 2.25” x 1.75”  

Thanks for looking!  As always, from a smoke free home.
