For your consideration is this pretty circa 1900 pin. It has a loop at the bottom and was probably a chatelaine pin. It has a ruby ( pinker that it came out in the pictures) and a seed pearl in an attractive flower etched setting. It has a tube hinge consistent with the era. I think it might be rolled gold or gold filled.
It measures 1 and 1/2 inch by 7/8 inches.
It is in excellent functioning condition. The back could use a cleaning. The front looks great...please ignore shadows.
