Figures wearing a headdress with a single protrusion from the crown of the head, known as the Oro, are found only among the Ọba and a select category of palace dignitaries whose ancestors originated in ancient Ile Ife ( ; Ọbazee 2025, p. 407). Only the Osa and Osuan, custodians of the Uwen and Ora deities, as well as members of the Emuru, who are responsible for the care of Iru vessels, may wear a headdress with the Oro. The identification of different figures is therefore interpreted based on the combination of the Oro with other items of regalia. Artists in the Igun-Ẹrọnmwọn and Igbesamwan depicted figures with the Oro on Ama-Ẹrọnmwọn (bronze relief plaques) and Aken'ni Elao (carved tusks), respectively. The Oro would either be made of coral beads as part of the crown or headdress, or be woven from itoto fibre ( ).

Odigba (coral-beaded collar) is a rigid neck collar made of coral beads, worn as part of ceremonial attire only by senior princes who have been made Enigie (Inneh 2007, p. 107). Although Ibafe (2007, p. 43) argued that the Odigba was introduced during the Ogiso period (c. 900–c. 1170 AD) by Ogiso Ere, along with other symbolically important Emwin Arhe, such as the Ada (ceremonial sword) and the Ẹbẹn (ceremonial sword), this seems unlikely, as coral was only introduced in the late 15th century through trade with Portuguese merchants.
