A late Victorian or Edwardian glass and metal button in an jewel-tone amethyst color.  The glass center is multifaceted.  It appears to have a foil background.  The outer rim of the button is brass.  A narrow trimming in a rope design separates the glass jewel from the rest of the smooth metal. 

This is a two piece button, with the metal of the back in a painted surface.  Shank back. 

Size of the button is 1-1/2" diameter. 

Condition:  Some wear and dings to the surface of the brass.  Condition of the glass center is quite good with no nicks that I see.  Some surface scratches to the black surface on the button back.

A pretty button for crafts, dress or costuming making.
