Description
All of the Crystal Gems have the ability to summon weapons and shapeshift. It appears that they have specialized abilities as well, such as Pearl's holograms and Garnet's psychokinesis. All of the Crystal Gems are wearing stars somewhere in their outfits. Steven's is on his t-shirt, Garnet's is on the chest area of her body suit, Amethyst has star shaped holes cut into her leggings, and Pearl's is on her shirt.

Currently, Steven is the only male member of the Crystal Gems on Earth. According to "Laser Light Cannon", Steven's mother, Rose Quartz, had to give up her physical form to bring Steven into the world. It is unknown if this applies to every Gem, should they want to have a child. Rose passed her gem, a rose quartz, to Steven.

In the "Pilot" and "Cheeseburger Backpack", it is implied that the Crystal Gems are over a hundred years old. It is possible that there are more Crystal Gems because Pearl mentioned that there were many Gems on Earth in the past.

Trivia

 * All of the Crystal Gem's weapons (including Steven's shield) have the same color scheme as their gem.
 * Steven is the only member of the Crystal Gems whose skin isn't the same color as his gem.
 * Their gem placement seems to corespond to their personailities, actions, and how they think. Amythest's gem is over her heart; she tends to respond to whatever her heart tells her and does whatever she wants. Pearl's gem is on her forhead for her brain; she tends to overthink things and be a perfectionist. Garnet's gems are on her hands; she tends to not talk often and respond through action instead. Steven's gem is over his stomach; he tends to go with his gut instinct and is often hungry. Their summoning of the gems tends to also match their gem placement.
 * All the Crystal Gems can shapeshift, but Steven and Amethyst are the only ones shown doing it so far.

Stevan skin may be because his gem is red like Garnets or because he is half human.
