The Golden Cross Tiara. The tiara, which is made solely out of gold, with no gems or other metals as embellishments, was originally made for Queen Marie of Romania. This tiara is still in Serbia. It is on display in a small museum in Oplenac, beside a grand church and mausoleum where members of the royal family are buried. In recent years, Princess Brigitta (the wife of Prince Karl Vladimir) has been photographed in the tiara.
