The Portuguese Crown Jewels (Jóias da Coroa Portuguesa), also known as the Royal Treasure (Tesouro Real), are the pieces of jewelry, regalia, and vestments that were used by the Kings and Queens of Portugal during the time of the Portuguese Monarchy. Over the nine centuries of Portuguese history, the Portuguese Crown Jewels have lost and gained many pieces. Most of the current set of the Portuguese Crown Jewels are from the reigns of King João VI and King Luís I.
