Gems/Gem Types

This is a list of gem types featured in both Steven Universe and headcanons by BlueWhiteLight and his friends. Each Gem is made with a purpose and designed to fulfill their roles or jobs. A gem type will be identifiable by their gemstone and appearances. Some Gem types, like quartz, share a general role with specifics based on sub-species. Other Gem types may come from the same species, but have two completely different roles. Rubies and sapphires are the best examples for this as rubies are common soldiers while sapphires are rare aristocrats. The Gem types on this page are listed based on the Homeworld caste system.

The Diamonds
The diamonds are the matriarchs of Homeworld, collectively called "the Great Diamond Authority". They have the highest ranking among all Gems and are praised by their underlings who serve them. Each diamond is different, having their own unique appearance and role. However, they can share similar physical characteristics such as towering heights and diamond-shaped pupils. It isn't known how diamonds are formed, whether they are grown in a special kindergarten or created by other means. In Gem society's history, four diamonds are known to exist. The Gem War caused by the rebellious Rose Quartz dwindled their number to three.

Known Members:
 * Blue Diamond: Although not directly stated, Blue Diamond seems to oversee the diplomatic side of Homeworld. Since the aftermath of the rebellion, she has been neglecting her duties and trying to preserve as much as she can of Pink Diamond's legacy. Her unique ability is radiated Pathokinesis, creating an aura of sadness causing those affected by it to cry.
 * Pink Diamond: A presumably off-colored diamond, she was the former member of the Great Diamond Authority. Due to her love for the Earth and resentment towards the other diamonds, she faked her own shattering and took on a new identity as Rose Quartz. Since she is Rose Quartz, she has her abilities: healing, phytokinesis, and floating. In A Single Pale Rose, it's revealed she can create non-sentient gem shards by applying pressure to dirt. It's not known if this is an ability all diamonds share or unique to Pink Diamond.
 * White Diamond: Not much is known about White Diamond except that she is the assumed leader (or at least most senior member) of the Diamond Authority. She is thus the paramount ruler of all Gems and the intergalactic Gem Empire. It is stated that she isn't like other Gems or even the other diamonds. Reportedly White Diamond hasn't left Homeworld in eons.
 * Yellow Diamond: Yellow Diamond has complete control over Homeworld's military. This also included experiments and weapons designed for military use, like the Cluster. Yellow Diamond has exhibited incredible strength and electrokinesis, powerful enough to destabilize a Gem's physical form.
