It can be turned into a scepter that Stella usually uses to help cast spells, or teleport herself and other people to a certain place. According to Stella, the ring is made of 6.1 pure magic.
It is cyan blue. When it is in its ring form, it is a ring with a sun-shaped circle. Same goes with the scepter form, except it is now much bigger and instead of the ring there is long staff with the sun-shaped circle being on its top.
The base is cyan blue. It has six orange jewel spheres on top - one in a middle and other five around it forming a pentagon. While transformed in a scepter it has a cyan blue sphere on top of it, but instead of the big wheel alike ring around it, it has six orange jewel spheres, once again - one in a middle and five around it forming the pentagon. On outside there's also five small spheres attached to the bigger ones.
Chimera's scepter is different. It is a purplish, darker version of Stella's Scepter that's shaped like a diamond with a purple jewel.
It is a part of the lineal right of the Princess of the Sun and Moon of Solaria and has been in the royal bloodline of Solaria since forever. It was forged so long ago that no one remembers when. It was carved out of a stone, immersed in the Spring of Light which still flows in the universe. The ring was also considered as one of the most precious gifts offered by the Dragon Flame.
In "An Unexpected Event," Stella uses her scepter against Knut and his ghouls in Gardenia Park, which Knut then steals as his ghouls restrain her, but she is able to recover it due to Bloom's unintentional attack.

The Trix, who are in an abandoned warehouse with the Winx, give them an ultimatum: the ring for Stella's life. The Winx are prepared to fight, but Bloom decides they cannot risk Stella's life and hands over the ring, freeing Stella.
In "Mission at Cloudtower," Bloom finds a book explaining the origins of the ring, and the Winx learn that it is an important and valuable object passed down through generations of Solarian royalty, partly created by a spring of light born of the Sacred Fire, but this does not explain why the Trix are so eager to have it. Later, the Winx decide to infiltrate Cloud Tower in order to reacquire the ring. Meanwhile, the Trix attempt to tap into the power of the ring but yield no results. They angrily conclude that the ring does not contain the power of the dragon as they hoped. Later, the Winx enter the Trix's dorm and Stella finds the ring.
