the Black Cross
A knight with the black cross or medieval Teutonic knight was a member of the Catholic military order Deutscher Orden or Teutonic Order, officially founded in March 1198 CE. With their famous black cross on a white tunic, the austere Teutonic Knights became masters of trade and diplomacy, carving out vast swathes of territory from their base in Prussia and building castles across Europe, from Sicily to Lithuania.
Each piece of jewelry in the collection bears a small black hematite cross.
