This is a stunning retro windmill charm/pendant set with a single Japanese akoya saltwater cultured pearl.

The pearl is 4.00mm round. It has good luster and bright pink overtones.

It is made of solid sterling silver and the blades spin freely! It is stamped "STER" and has a makers mark I cannot read. Total drop is 1 1/8in including the bail. 

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