Oxum is the goddess of the river, love,gold, and sensuality. Gold and yellow are her colors, explaining why this crown is apparently made of brass. The five-pointed star is also very appropriate, as five is the number of Oxum. Though some avatars of Oxum are warriors, unlike Ogum and Oxóssi, she is still represented with royal iconography, e.g. a crown.  

The veil of beads dangling from the crown are known as a choráo, or crybaby. The choráo is meant to imply tears.  According to Sr. Costa it is  also reminiscent of headpieces that cover the faces of Yoruba monarchs and protect onlookers from their gaze.

Though he did not make the crown, Sr. Costa repaired the choráo once when it was broke. The intricate overlapping pattern required much skill to repair. One should keep in mind the skills necessary to make and maintain these objects, as well as any costs associated.
