Princess Helen wearing her famous Greck key tiara :
Helen seems to have been one of the princesses of Europe's poorest jewelry. In fact, I only know one tiara, the one that gave her her stepmother Queen Marie on the occasion of her marriage to Carol of Romania.
It may seem strange that neither her paternal grandmother, Queen Olga of Greece or her own mother Sophie of Prussia have offered her any other ornaments on the occasion of her wedding.
Helen, however, destined to rule one day in Romania, had much less of jewelry that some of her cousins - like Olga of Yugoslavia - which would not inherit any throne.
