Eternal Golden Crown (エターナルゴールデンクラウン Etānaru Gōruden Kuraun?) also known as Golden Crown (黄金の冠 Kogane no Kanmuri?) (or Golden Crown of Wisdom in the English dub Glitter Force Doki Doki) is the last and third Sacred Treasure, wielded by one of the three legendary Pretty Cure warriors, Cure Priestess, in the past.
The Eternal Golden Crown was once kept in the Trump Kingdom as a lock to keep the Selfish sealed away, but the king removed it, breaking the seal and releasing the Selfish, which transformed the king. The crown was hidden away in a forest until Princess Marie Ange guided Joe to its location and brought it back to the Pretty Cures. At first, Mana tried to use it but it failed, then Aguri touched it, allowing her to see the visions and the truth about her and Regina, resulting in her fainting. She later takes it to Regina and bets it on a battle for the Miracle Dragon Glaive, and causes a fight between her and Regina. Though the fighting ends badly, as both girls are injured, Cure Ace then tries to destroy Regina, however, Cure Heart protects her. DDPC45
