Diana is a Munchkin cat with a jet black body and white paws and hair fluff. Her Jewel Eyes are made out of silver diamonds. For her attire, she wears a pink bow to hold up the hair fluff, a lace-trimmed pink shawl and a white pearl necklace with a silver heart-shaped diamond jewel attached around her neck.
In the first series, her overall appearance remains the same, but her eyes are shaped like curves, representing her role as an antagonist.
Diana's Jewel Charm is shaped like a house; it is a large black diamond with pink ornated swirls on its sides. It has a pink fence at the bottom, decorated with small black diamonds.
According to the official website, Diana is generally depicted as precocious and elegant. She can also be very loyal to her friends and is always there for them.
In Jewelpet, she is very sneaky and very cruel to the Phantom Herb Thieves, the people who work for her. In a few episodes of the series, she is shown to be nicer than usual. She is known as a "dark Jewelpet" in this series, acknowledging her dislike and hatred towards bananas.
In Jewelpet Kira☆Deco!, she is a bald wig comedian who highly demands people to make her laugh. She seems like an airheaded Jewelpet at first, but later reveals her true motives and forcefulness in episode 49.
As the Jewelpet of Charisma, Diana's spells allow humans (mostly girls) to easily attract others, giving them a strong presence and inspire their devotion and loyalty for them. In Lady Jewelpet, her jewel is described as having the power of eternal love and brilliance, as well as purity.
In Jewelpet, Diana is able to cast lightning using her paws.
Diana is the main antagonist of the first half of the series. She seeks to collect the lost Jewelpets for herself and curse humans in order to attract them; her purpose behind all of this is to awaken her brother Dian. She employs the Phantom Herb Thieves, who she treats poorly. Before she met them, Sage, a member of the Phantom Herb Thieves, found a kitten which looked like her and fed it milk, but later it got lost. Afterwards, Sage found her Jewel Charm and was awoken by him, who tricked and persuaded him that she was the lost kitten and demands to be awakened from her Charm state, which he does out of her orders. When she finally found Dian trapped in his crystal prison and freed him, Diana then served as his right-hand assistant, who also admires him for his good looks. In the last two episodes, Diana witnesses her brother transform into Dark Dian and has no choice but to try to restore him back to normal. When Rinko and the Jewelpets finally restored Dian to normal, Diana then hugs him as a sign of gratitude and turned into the side of good along with her big brother.
Diana is the most prominent member of the elite, rivaling the Rose class. She's also Dian's on-again, off-again girlfriend, which Dian dumped Garnet to get back with after she taped her eyes closed and about to cry.
Diana has frequent, seemingly pointless appearances in the background wearing a bald wig. Occasionally the main characters notice her but pay her no attention. It turns out, in episode 49, that those appearances were attempts to get other people to do comedy routines with her; being ignored all of the time, she demands them to make her laugh.
Diana appears very briefly in episode 32, where the Petite Ladies have to choose jewels for their rings. Diana's jewel is talked at length about how valuable it is. Luea claims that she is going to borrow a diamond from her because she doesn't want Lillian to use her own jewel, the blue apatite.
