This study stone costume necklace is equal parts witch and seriousness. American Brutalism was popular as a style from the 1950s through the early 1980s or so. The style, metal, and choice of stone of this piece leads me to believe it is from the 70s. This is what you wear to the work meeting for your presentation -- she's serious but she's mysterious, too! A fun vintage find at a great price. The item is in good vintage condition. The chain measures 24 inches.
