Perhaps they are the perfect colors for you, or maybe you like them because they are in Jet/Hyacinth, the official school colors for such teams as Oklahoma State University, the Cincinnati Bengals and many more. Each measures 18mm in diameter, not including the loop or the ear wire. Made with Austrian crystals. Sold by the pair. Manufacturer direct from a trusted supplier.
