This deco pattern is from the 1930s. It is found in crystal rose, azure, green, amber, ebony, and topaz. When it has gilding that is considered a Crown Decoration. This line has only serving and decorative pieces. The candlestick is 2 inches tall.
In the 1950s and 60s Fostoria sold some stemware that was called Diadem (line #6056) but it does not look like it was made for the original Diadem pattern.
