This is a lovely vintage designer pearl brooch with baroque blue/gray Japanese saltwater akoya cultured pearls.

The pearls measure 7.50-8.00mm with a silver/blue body color. They have very good luster with light pink overtones. 

It is made of solid sterling silver and has a swirling abstract design. Stamped "SILVER" for solid sterling silver and "VIVO" for the designer. It measures 1 3/4 inches long. 

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