This is a beautiful vintage Art Deco rouge compact in sterling silver and aqua blue guilloche enamel with a chain and finger ring. The compact is octagonal in shape and the engine turned design is lacy and delicate. It has a gold wash on the interior and the mirror is clear and unclouded. It is marked Sterling 4487 and it has a maker's mark that I can't identify. It dates to around the 1920s.
The compact itself measures 1 1/2 inches in diameter and it is about 3/8 inch thick. The chain and ring are 4 inches long. It is in very good condition with no damage to the enamel and only light surface wear.
