"A bijou is a mixed alcoholic drink composed of gin, vermouth, and chartreuse. Bijou means "jewel" in French. It is said to have been invented by Ezra Star. This cocktail is called Bijou because it combines the colors of three jewels: gin for diamond, vermouth for ruby, and chartreuse for emerald" - Wikipedia
