Fabulous Art Deco sterling silver chrysoprase and marcasite ring. The focal point of this wonderful geometric styled ring is a large oval green agate, accented by marcasites. They used very tiny marcasite stones in the vintage pieces, giving them a wonderful sparkle. This beautiful ring sits close to the finger, making it easy to wear. It measures 1 inch long and is a size 5.75. The inside of the band is marked sterling. I did not polish the silver since these vintage rings look great with the patina they acquire over time. It is in excellent condition, and dates to the 1920's to 1930's.
