This is a pendant top by Edison Sandy Smith. It's an old design that you don't see anymore, and its size gives it a strong presence. I've been collecting Edison's work for over 20 years, but I've never seen a similar design. I think those who like it will find it a special piece. The stone color is a lighter blue than in the photos. The type of stone is unknown. The silver is thin. Approximately 6.4 cm long including the bail. Approximately 4.8 cm wide. Bail inner diameter is about 6 mm. I think it can accommodate a relatively thick Navajo chain. This is an old, handmade item, so please understand.
