The term 'Tiara Adorners' refers to those who adorn tiaras with GEMS. GEMS are precious stones, often cut and polished, that are used to decorate jewelry and other items. Tiaras are a type of headdress, usually made of metal and decorated with jewels, that is worn by royalty or other people of high social status. Tiara Adorners are responsible for selecting and setting the GEMS in the tiaras to create beautiful and unique pieces.
