This product is a vintage green Vaseline glass cordial stem featuring a retro "Comet in the Stars" pattern. Manufactured in the United States in 1914, the decorative glass piece glows next to an Ultraviolet Light, adding an extra special attribute to its appeal. Standing at 4-1/2" tall with a 2" diameter base, this original Depression glass piece from the early 20th century is a unique and collectible addition to any pottery and glass collection. It is attributed to U.S. Glass in 1914 but has been made by other companies and the "look" varies from piece to piece.
