This is a cute vintage mid-century Japanese akoya saltwater cultured pearl leaf pin by Beau.
It features four pearls and delicately detailed spade shaped leaves. The pearls measure 3.75mm and have good luster with light rosy overtones.
It is in solid sterling silver and is stamped "STERLING" and "BEAU". It measures 1 1/8 inch across.
All pearls are truly vintage and have only been lightly cleaned. Some very dark patina on the back.
