This is a great mid century modern circa 1950s -1960s vintage demi parure brooch and earrings set of rounded concave triangles each set with a single large sparkling aurora borealis rhinestone. There are no markings. They are base silver tone metal with a purposefully applied dark patina. The earrings have clip backs. The brooch has its original pin back with functional roll over safety catch.
The brooch measures 1.75" x 1.25". The stone in the brooch is 15mm in diameter. Each earring measures 1.125" x .75". The stones in the earrings are each 8mm in diameter.
Condition is good. I note that some of the dark finish has worn off the backs.
The shape of these pieces reminds me of the classic mid century modern coffee tables - very space age/George Jetson-esque. Cocktails anyone?
