Beautiful Silver Foiled Pink Paste Earrings. Made of "paste", a special glass and lead formula originating from George Ravenscroft, a London glassmaker, during the 17th century and perfected by a French jeweler Georges Strass in the 18th century. Each "paste" was hand-carved to fit the setting. Paste has become very collectible and desirable and can no longer be made today. The earrings are backed in a 15K gold shepherd's hook.
