My guess at age is 1940's when having a powder box on your vanity was all the rage. The top is a plastic blue with a guilloche enamel rose in the center of top. The glass bottom has a ribbed surface with tulip panels all around. Over all size is 3 ½" in diameter and 1 ¾" tall. No chips or cracks on glass base with metal top inside has some discoloration. Please check out pictures for a better look at this sweet little catch all powder jar.
