Geneva sugar bowl. Custard glass. Glows bright under black light. Originally called Ivory color, lighter than most custard glass. Decoration has been called the "Christmas Decoration." We think that this is a sugar bowl without the top. However, we have been fooled before as some spooners also have the rim used to hold the sugar top on the sugar. We believe that the spooner is more narrow than this piece. Height is about 4 inches. Diameter is about 4 1/4 inches. The second photo shows the inside rim.
