Gorgeous vintage Marsala Marcasite and Aquamarine Pendant

Gorgeous VTG Marsala Marcasite and Aquamarine Pendant Stamped with Marsala hallmark on the back and a very smeared 925. See other listing of matching earrings that I purchased at the same time as this pendant back In the 90s. (The 925 on the earrings is much clearer) It is just over 1/2” long (9/16” to be more exact) Being offered WITHOUT a chain at the moment
