Description
All of the Crystal Gems have the ability to summon weapons and shapeshift, as well as the ability to fuse with each other like Opal who appeared in the episode Giant Woman. It appears that they have specialized abilities as well, so to bring Steven into the world. It's 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 correspond to their personalities, actions, and how they think.
 * Amethyst's gem is over her heart; she tends to be fun loving, and often does whatever she wants.
 * Pearl's gem is on her forehead; 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.
 * It has been revealed by Pearl in So Many Birthdays that Gems do not age and will not die unless they are killed in battle.
 * While Gems can't die from food poisoning, they can still get extremly sick to the point of vomiting.
 * This does not apply to Steven, a half-Human, half-Gem. In "So Many Birthdays," Steven accidentally ages to the point of near-death.
