This is a stunning Modernist design done in sterling silver and set with a gorgeous natural stone. It is a green stone similar to malachite but with beautiful figuring and shades from light green to the deepest green. This piece is a pin but also has a loop for a chain so it can be worn as a pendant also. It is a little over 1 3/4" x 1 1/4" and in excellent condition. It is marked Sterling Silver Israel. This pin weighs about 20 grams.
