This is a stunning and unusual geometric chrysoprase and Japanese akoya saltwater cultured pearl ring.

The pearl measures 5.25mm round. It has good luster with light rosy pink overtones. It is surrounded by four bright green tablet cut chrysoprase gemstones. None are chipped or scratched. 

It is set in solid sterling silver and is stamped "925". US size 6 1/4. From mid-century. Very unique design.

All pearls are truly vintage and have only been lightly cleaned.
