The Royal Sovereign of Naboo medal was a circular decoration, gold in hue, that had a shape akin to a crescent moon with its tips connected. The sovereign of the Royal House of Naboo would wear it to symbolize the people of Naboo under specific conditions.
In the year 32 BBY, Padmé Amidala, then the Queen of Naboo, displayed the medal on the front of her escoffiate headdress. This occurred when she addressed the Galactic Senate, requesting an end to the Trade Federation's planetary blockade against her homeworld.
