Bloodstone

"There's a lot riding on each and every target. Every gem takes aim at their goals and each and every one of them delivers."

Bloodstone is a Homeworld Gem and antagonist who made her debut in "New Kid". She is a spy and bounty hunter who strays from the Gem Homeworld to carry out her own plans, and as a result leads an underground black market operation that goes against both the Crystal Gems and the Gem Homeworld.

Often, Bloodstone is seen with her affiliated second-in-command Obsidian. The two of them even went as far as kidnapping Percy for their underground experiments, leading to his artificial transformation into Platinum. As of "Platinum", her whereabouts are currently unknown, though she still resides somewhere on Earth.
