This large pin dates from between 1900 and 1920. It is called a "sash" pin or "cloak" pin and was worn on outer garments. It is made of brass that was patinated and will not change color. It has a wavy look to the surface and the brass is brighter atop the waves. There is an Arts & Crafts quality to the design. The round cabochon stone is dark orange in color and resembles coral but is probably faux. This pin is in excellent original condition. It has a C-catch, consistent with its age, and stays clasped because it has a spring. An earring or stickpin clutch may be used as a safety, if desired. This pin measures 2 5/8" long X 2" high X 1/2" thick. It makes a great scarf clasp.
