This is a stunning vintage flower Japanese akoya saltwater cultured pearl brooch.

The pearl is 5.50mm round. It has lovely luster with rosy overtones. It is set among detailed flower petals. 

It is made of solid sterling silver and has a unique design. It measures just over 1.75 inches long. It has stippling and engraved details. A lot of care was put into its design. Stamped "STERLING". Some heavy patina due to age.  

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