A Brilliant Circlet is a Circlet-class headwear found in Golden Sun: The Lost Age. It is one of the prizes that can be won in the Lucky Medal Fountain in Lemuria. Being a Circlet, it can be equipped by Jenna, Ivan, Sheba, and Mia.

The Brilliant Circlet increases the wearer's defense by 36. It also increases the wearer's luck by 10, the second highest luck rating in the game. It can be bought for 6100 coins and sold for 4575 coins.

Although a useful item, the Brilliant Circlet may not see much recognition compared to other prizes such as the Crown of Glory or Leda's Bracelet. It may see some use, however, if the player chooses to equip any Crown of Glorys they won to Felix and Piers. Late in the game, however, it may easily be replaced by stronger equipment, such as the Psychic Circlet or Berserker Band.
