This is a delicate vintage floral Japanese akoya saltwater cultured pearl brooch.

The pearls range from 4.75-8.00mm. They have lovely luster with light rosy overtones. The smallest pearl is more of a cream color while the larger are a white/silver color. They are set among delicate filigree flower buds. 

It is made of solid sterling silver. It measures just over 1 1/2 inches long. A lot of care was put into its design. Not stamped but tested solid sterling silver.

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