The Crystal Heart is located in the center of the Crystal Temple. It was first seen in the episode "Together Breakfast", and most recently in the episode "Catch and Release".


The Crystal Heart resembles a huge, red, crystal structure. Pearl stated that it is connected to the most dangerous parts of the Temple. The central vein connected to the bottom of the Heart leads directly down into the Burning Room from Rose's Room. Due to the rhythmic beating and vein-like apparatuses, the Crystal Heart gives the Crystal Temple a sense of being alive. It is unknown why the Crystal Temple contains a heart, the effects that it has when removed, or where it draws its power from. However, it can be assumed that the Heart powers the Crystal Temple.


"Together Breakfast"

Steven gripped onto one of the blood vessel tubes and then slid down it while seeing into other rooms.

"Secret Team"

Amethyst and Steven attacked and collected the escaped arms on its vessels.

"Catch and Release"

Steven rides the central vein from Rose's Room into the Burning Room to question Peridot about her behavior at the Galaxy Warp, mentioning the Cluster.


  • The Crystal Heart connects to all known Crystal Gem rooms: Amethyst and Pearl's rooms are connected via corridors on the main floor. The vein beneath the heart goes through Rose's Room (seen within the room in "Catch and Release") and leads directly to the Burning Room.
  • When Steven slides down the central artery, the middle area is Rose's Room, hinted by the primary tune played in the episode "Rose's Room" and its overall cloudy appearance.
  • Smaller, seemingly organic hearts that may be similar to the Crystal Heart can be seen inside the Injectors in the episode "On the Run" and subsequent appearances of the Kindergarten, although the location and its technology are currently inactive.
