This is an American made sterling silver topped and cut glass, or crystal, bottle perfume horn or vial for the dressing table, or to be worn as a pendant. The sterling top is a hinged lid decorated with a large winged cherub's head surrounded by acanthus foliage. Maybe it is an angel's head? The silver is marked "STERLING". There is also a sterling ring attached to the top that would make it possible for the perfume horn to be worn on a chain or ribbon.
The glass is cut in a zipper cut and the perfume vial itself is in the shape of a horn. This shape and the cutting to glass helps prevent this bottle from rolling when laid down. So, this should prevent accidental breakage as the bottle will not roll off of the dressing table and onto the floor.
The contents of the vial are protected with a ground glass stopped, that is intact. The silver and the glass are both in great vintage condition with no dents to the silver nor chips to the vial or the stopper. Circa 1900.
