Collectable Vintage Pentant and necklace, old Marcasite

This is a gorgeous old piece, apparently bought from Kay's Antiques... Selling because it's not my style.  Sterling silver unique chain, marcasite and cubic zirconia dangling pendant.

The pendant and chain are unique, as per the pictures and are sold as a set.

Some knowledge.......Marcasite jewelry is jewelry made using cut and polished pieces of pyrite (fools Gold) as gemstone, and not, as the name suggests, from marcasite. Both pyrite and marcasite are chemically iron sulphide, but differ in their crystal structures giving them different physical properties—also known as polymorphism.
