This artist made art glass brooch was once sold at the Metropolitan Museum of Art in New York where I originally purchased it in the early 1980s. It comes in the original box with the Museums name on it. 
 
The brooch is a limited artist made design. It is a modernist free form design in Amethyst glass with applied layered glass in red, white, and sienna. 
 
It is a large presentation brooch that measures 3 1/4" long x 1 1/2" wide and is not signed. The pin is all new and never worn and in perfect condition. 
 
Comes gift wrapped and shipped in a new presentation jewelry box. 
 
* You can add a gold or silver brooch slider to convert this pin to a vertical pendant by checking the option box.
