The Brilyantes are fictional gemstones in the Filipino fantasy television series Encantadia as well as its 2016 requel. They are the elemental gems that holds the balance in Encantadia. Each gem manifests the classical elements: aether, fire, air, water, and earth. The tranquility and future of Encantadia rests on these gemstones. In both series, each Brilyante are being carefully kept by each kingdom in Encantadia. The kingdom of fairies, Lireo, in the east of Encantadia, is the keeper of Brilyante ng Hangin (Gemstone of Air). Adamya, the kingdom of elves in the south is the keeper of Brilyante ng Tubig (Gemstone of Water). Sapiro, the northern kingdom of valiant warriors and healers, kept the Brilyante ng Lupa (Gemstone of Earth). Hathoria, the kingdom of proud and violent blacksmiths and orcs in the west, is the keeper the Brilyante ng Apoy (Gemstone of Fire). But after the Hathoria attempted to seize the all the gemstones, they are turned-over to Queen Mine-a of Lireo for safekeeping. Later, the four daughters of Queen Mine-a became the keeper of these gemstones.
The four brilyante first appeared in Encantadia, but the history of the gemstones appeared on its prequel, Etheria. The history of the four elemental gems date back to the First Great War in Encantadia with the fall of the Etherian Empire.
The four brilyantes were initially created as a single gem that the deity Emre, the highest god in Encantadia, bequethed to the leaders of each kingdom in Encantadia; it was called as the Brilyante ng mga Elemento (Gem of the Elements): King Bartimus of Hathoria, King Meno of Sapiro, Queen Cassiopeia of Lireo and Elder Aegen of Adamya, used it to aid them in their struggle against the abusive empire of Etheria (followers of the fallen snake deity, Ether) under the rule of Queen Avria. The gem contains the four elements that will keep the balance in Encantadia. After the fall of Etheria, the jewel was entrusted to the most stable nation at the time, Sapiro. Fearful that the gem's power will corrupt Sapiro, Cassiopeia, the first Queen of Lireo, made the fateful decision and used the Kabilan Sword (the sword once belong to Etheria) to break the gem into four fragments that embodies the four elements it contain: water, fire, wind and earth. Because of this act, the four kingdoms of Encantadia lost their alliance with each other and Cassiopeia was cursed by Bathalang Emre and banished from Lireo. The four gem fragments were vested upon the four kingdoms. Sapiro was given the Brilyante ng Lupa, Hathoria was given the Brilyante ng Apoy, Lireo was given the Brilyante ng Hangin, and Adamya was given the Brilyante ng Tubig.
