Quartzes

Quartzes are a broad category of ,Gems that served as the primary soldiers in Homeworld's Caste System.

Role
Quartzes were initially a soldier caste; some individual Quartzes, such as Jasper, were used as bodyguards and escorts. They appear to be less numerous than Rubies. Some have defensive powers. Quartzes are made to fight. Some also act as guards at Homeworld outposts such as Pink Diamond's Zoo. They were commonly made on Earth. Quartzes are the most diverse known Gem type with Gems including Amethysts, Carnelians, Jaspers and Rose Quartzes.

Other Quartz types include Agates, who rank higher and seem to be administrative in nature and Citrines, who seem to be elite guards.

Physical Characteristics
Quartzes are much larger than most other types of gems, made to fit the role of an elite warrior. Quartzes have incredible height, broad shoulders, and an intimidating muscular build. While their exact height can vary depending on how well they formed when they were incubating in the ground, most Quartzes appear to be the same height as each other, with variations of this standard height being very rare. Quartzes have some of the longest and thickest hair of any gem, though Agates in particular tend to have their hair styled into short, neat buns to denote their rank. Their hair color is often a very pale tone of the color of their gem, although some have dark brown hair. Some Quartzes may have patterns and bandings on their skin, resembling that of their real-life counterparts.

All Homeworld Quartzes wear the standard Homeworld uniform, while Quartzes with a more managerial position, such as Agates, wear an additional shawl and boots. Decorated Quartzes, such as Jasper, can also wear a cape over their uniform, though this isn't actually a part of their physical form.

When corrupted, Quartz Gems take the form of a giant eyeless wolf-like beasts with chimeric features. They have a furry mane which extends down their back and covers their tail, and have large muscular forelimbs ending in broad forepaws that resemble hands. Their hind limbs are relatively lean and gaunt, ending in cloven hooves like those of an ungulate. They have a large, bulldog-like head with a prominently fanged underbite and a varying number of horns on their heads or where their facial features would be. Quartzes that have been uncorrupted generally have "scars" that manifest in variable extremes depending on the duration of corruption; Those who have been corrupted for over thousands of years exhibit a full set of horns identical to that of their corrupted form and permanently lose their eyes and nose (though some individuals might retain them). Despite this, their vision doesn't seem to be impaired in any way.
