The conference posed itself several questions. What were the changes in the typology, style and technique of jewelry art in this period? What role did the evolution of the jewelry business play in the personal preferences of monarchs, the aristocracy and the bourgeoisie? How were the political and military cataclysms, socioeconomic changes and technological achievements of the early 20th century reflected in the jewelry business of the time? How did collectors' tastes change, and what place did jewelry art hold in private and museum collections?
