Quartzes

Quartzes are a broad collection of Gems cuts that serve as the primary soldiers of Homeworld's Caste System. Some Quartzes are higher ranking than others, being described as "elite" or holding commander positions while the majority mantains a common soldier ranking.

Amethysts
Amethysts are purple colored Quartzes, most notably produced on Earth's Prime Kindergarten for Pink Diamond. Besides Amethyst 8XM, the Amethysts from Earth were stationed at Pink Diamond's Zoo thousands of years later, now serving Blue Diamond and are commanded by Holly Blue Agate due to the "shattering" of Pink. Like Amethyst 8XM, these Amethysts share a laid back and comedic personality.

History
Four Amethysts appear in "Gem Heist" at Pink Diamond's Zoo; two of them are in charge of guarding the door in the Zoo's cargo bay. The two Amethysts tease the Crystal Gems when they land on the Zoo, resulting in a scolding from Holly Blue Agate. Later in "Gem Heist," another pair of Amethysts send Steven into the Zoo's tunnel, one with a square-faceted gemstone.

In "The Zoo," several Amethysts are seen entering the boundaries of Pink Diamond's Zoo to console the heartbroken Zoomans. One Amethyst later angrily informs Greg and Steven of the trouble they are in.

In "That Will Be All", this turns out to be a prank by Amethyst and the many other Homeworld Quartz guards she has met (whom she refers to collectively as "the Famethyst"), three of which having been formed right above her. These Amethysts inform her of her serial number being Facet-5 Cut-8XM. Among the Amethysts and Jaspers are two defective Gems: "Skinny", a tall and skinny Jasper, and Carnelian, shorter than most Quartz.

In "Now We're Only Falling Apart", numerous Amethysts are shown emerging out of the Prime Kindergarten in a flashback from Pearl.

In "Together Alone", several Amethysts and Jaspers are shown in the crowd of Quartz Gems dancing alongside the Crystal Gems' Amethyst during the Era 3 Ball.

"Now We're Only Falling Apart"
Many Amethysts appear in Pearl's flashback, all of which emerging from the Prime Kindergarten.

"Together Alone"
Several Amethysts attend the Era 3 ball, seen dancing along with several Jaspers.

Jaspers
Jaspers are a broad variety of Quartz soldiers that vary in color, such as Biggs Jasper and the Snow Monster. The famous Jasper describes her cut as never giving up and always getting what they want.

"That Will Be All"
Several Jaspers from the Beta Kindergarten debuted in That Will Be All. Like the Amethysts, they originally belonged to Pink Diamond but now served Blue. Despite their Gem type, they are all considered members of The Famethyst.

"Together Alone"
Two identical Jaspers attend the Era 3 ball, seen dancing along with several Amethysts .

Carnelians
Carnelians are a red type of Quartz, most notably the defective Carnelian from the Beta Kindergarten.
