The pin belonged to King Milan Obrenović. It was made of a bullet used in the attempted assassination of King Milan in 1882 at the Saborna crkva. Ilka’s assassination is just one of four unsuccessful assassinations of King Milan Obrenović. Jelena-Ilka Marković, the widow of Colonel Jevrem Marković, who was shot in the Topola Rebellion, was indignant because of her husband’s death and tried to assassinate King Milan. King Milan ordered that a decorative piece, a tie pin, richly decorated, be made from that bullet. The pin is continued on a gold ring with alternately placed rubies and diamonds. The lead bullet head is fixed in the ring itself.
