Yellow Diamond, as one of the rulers of Homeworld, is (20'0") beyond the usual height of most Gems on Homeworld. her height making a common pearl's pale in comparison. She has a pointed, upturned nose, plump lips and a thin long neck. Her hair is a short bob with two spiked tips. She has thick, black eyebrows, and two black dots of eyeliner in the bottom corners of her eyes. On the topic, her eyes are bright yellow with rhombus-shaped pupils. She wears a black and olive bodysuit similar to the ones worn by Jasper, Peridot, and Garnet. She accompanies it with a yellow cape with very large shoulder pads and a cutout for her gemstone. She also wears gloves with a slightly darker yellow and very dark olive yellow boots.
Yellow Diamond, like most Homeworld Gems, is shown to care little for the Earth and organic life.
She is part of the Diamond Authority, her faction seems to be the most "savage" of the 3, having a bunch of Guards and a great army always prepared to fight in the name of their kind. Yellow Diamond has a reputation for being cold. She gets stressed often due to the recent increase of riots, failed missions and 'incompetence' around her units, so she loses her patience often. However, in a certain way, she is the most reasonable Diamond. Normally, she allows certain gems to come to her base, and present their projects for their district. The district is well known due to her military presence, and high technology. They are entirely focused on both aspects, keeping the order with an iron fist.
Yellow Diamond possesses standard Gem abilities, but since she is a Diamond, her abilities are expected to be much greater than other Gems'.
- Electrokinesis: Yellow Diamond is quite possibly the strongest Electrokinetic gem on Homeworld, being able to destroy a gems physical form with the single shot of electricity, along with her being able to concentrate it into short bursts. Her Electrokinesis behaves similar to a gem destablizer.
- Enhanced Strength: Yellow Diamond is able to poof a normal gem with the press of her finger. This may be a simple question of physics rather than an ability, given the enormous size difference between a Diamond and a normal gem.
- Hyper-Comet Dash: She has the ability make a devastating spin-dash, similar to Amethyst's and Jasper's.
- Energy Boost: She has the power to engulf herself in energy, boosting her speed and ability to take damage.
- Energy Light-Saber
