This article is about the Jewelpet. For the human character in Lady Jewelpet, see Lady Diana.

Diana (ダイアナ Daiana?) is a female Munchkin cat Jewelpet who represents Charisma.


Diana is all black with white paws and a white hair fluff on her head. She has dark blue Jewel Eyes. She wears a pink bow to hold up the white hair fluff, a lace-trimmed pink waistcoat, and a pearl necklace with a heart-shaped diamond over it.

Dianna's charm
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.


Generally, Diana is early-matured and likes to be elegant. She can also be very loyal to her friends. She can be funny sometimes like in Kira Deco, where she goes from place to place wearing a bald hairnet like hat on her head.

However, in Jewelpet, she is very sneaky and very cruel to the Phantom Herb Thieves, 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 season, acknowledging her dislike towards bananas.

In Jewelpet Twinkle, just like her original counterpart, Diana is cruel and boastful around most people, but she is also very loving and loyal to her partner Alma Jinnai.


In Jewelpet (anime), Diana is able to cast lightning using her paws.


In Jewelpet (anime), she 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.

In Jewelpet Twinkle, she's the Jewelpet partner of Alma Jinnai, alongside Opal. Unlike Opal, Diana follows Alma's desires without much thought, therefore making her one of the antagonists.

In Jewelpet Sunshine, she's 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.

In Jewelpet Kira Deco, she 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.

In Jewelpet Happiness, she appears in a couple of episodes related to sports events and forms a Magic Gem with Sachi Hakamada, along with secondary Magic Gems with her again.

In Lady Jewelpet, she appears very briefly in the episode where the Petit Ladies have to choose jewels for their rings. Diana's jewel is talked at length about how valuable it is. Luea says that she's going to borrow a diamond from her because she doesn't want Lillian to use her own jewel, the blue apatite.
