This quote taken from Victoria Tillotson website "A scarce and wonderful example by Boston-based modernist jeweler Ella L. Cone, designer for and proprietor of The Silversmith's Shop which resided at 342 Bolyston St. during the 1950s and 1960s. designs by Danecraft and Beaucraft, furniture by Harry Bertoia and Scandinavian housewares as well. Cone's own jewelry is very much in keeping with American modernist aesthetic precepts, although she is also known for her figural examples." The pendulum swings. 1 1/2 inches long, almost 1 inch wide. Marked Ella Cone Sterling. Very good condition.
