Lovely MARVELLA starfish pin is covered with imitation pearls. It measures 2 1/4 inches in diameter and is signed on the back as shown. The pearls are in great shape, no nacre loss detected even under magnification.
A note about the company: Marvella jewelry was manufactured by the Weinreich Brothers in Philadelphia, PA. They made jewelry for many other companies as well and were probably most well known for their imitation pearl jewelry. Marvella also made popular figural jewelry and crystal necklaces. More recently, the company has been bought and sold a few times. The Marvella name is still being produced but manufacturing has moved out of the US.
