Diana is an all-jet black Munchkin cat with white paws and a white hair fluff on her head. 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 over it.
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 and is colored black with pink swirls at the top. It has a pink fence at the bottom, decorated with small black diamond shapes.
Diana is generally depicted as early-matured 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.
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 for 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. Afterward, Sage found her Charm, which tricked him that she was the lost kitten and persuaded him to get her awakened.
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 says that she is going to borrow a diamond from her because she doesn't want Lillian to use her own jewel, the blue apatite.

- Diana's jewel motif is the diamond, considered the most valuable gemstone, as well as the hardest material in existence. It is also one of the four precious stones, together with the sapphire, emerald, and ruby.
- Diana's birthday is in April; diamond is that month's birthstone.
- Diana is the second Jewelpet to have an alias (Jill, in Jewelpet Twinkle☆), the first being Dian.
- Both Diana and Dian are the only Jewelpets born as siblings. This is only true in the first series' continuity, however.
