Opal is a periwinkle-colored winged unicorn with a yellow-colored horn on her head and a purple mane and tail. Her wings are decorated with rosaries of blue, pink, and yellow jewels, and her Jewel Eyes are made of purple and blue opals.
Opal gets the most characterization in both Sunshine and Kira☆Deco!. Whereas the first series describes her as a calm and yet supportive Jewelpet, Sunshine made her into an insecure but determined character. Kira☆Deco! made her into an antagonistic character with a lady-like but wicked personality.
Opal is one of the only Jewelpets being in the Super Crystal class, as her magic is highly successful and powerful.
As the Jewelpet of Awakening and Miracles, Opal's magic can allow humans to achieve something extraordinary and awaken the miracle within them.
In Jewelpet, she is a Legendary Jewelpet, who can be summoned if someone has a Super Crystal class ranking. She was summoned first in episode 26 to defeat Diana in her giant form and later in episode 51 to attempt to defeat Dian in his dark form.
In Jewelpet Kira☆Deco!, she has an antagonistic role with Io, who has a crush on her. She has a boastful and egotistic personality and isn't afraid to show her love for gothic fashion. Like her Sunshine counterpart, she has a crush on Jasper, dancing with him at Garnet's ball in episode 24.
