The listing, Major Magnetic Expansion Bracelet - gold tone with 6 large, round cubic zirconias - Vintage has ended.
This is a magnetic bracelet - quite old - 1970's. The 6 magnets each contain a large sparkly round cubic zirconia. The magnets still work but are most likely, not as strong as they once were, so this bracelet would probably be more suitable as a decorative bracelet.
