Diamond Ships are one of the different transportation methods that the Diamonds use.
Blue Diamond's Ship
Blue Diamond's Ship is a massive blue left arm-shaped spaceship. The ship was owned by Blue Diamond until it was destroyed.
Blue Diamond's Ship is a large blue spaceship shaped like a left arm. Along the ship's arm and hand, sky blue lines are present and create square shapes in different parts of the exterior. A small hole on the ship's palm is used to act as an entrance for Blue Diamond's palanquin, which levitates from the hole into the ship. At the end of the arm, there is a light blue rectangle.
In "Steven's Dream", Blue Diamond grabs Greg and summons her ship. Steven watches in shock as Greg struggles in Blue Diamond's grip and pleads for her to let him go. Blue Diamond goes into her palanquin with Blue Pearl, and it floats up, entering the palm of her ship. Steven tries to give chase, using his floating powers until the ship blasts away at warp speed, causing him to start falling in the air. In "That Will Be All", the ship makes its second appearance at the zoo when Steven, Greg, and the Crystal Gems are leaving in the Roaming Eye. In "Reunited", Blue and Yellow Diamond come to Earth in their ships to release The Cluster. The ship is destroyed when The Cluster throws Yellow Diamond's ship onto Blue Diamond's ship. In "Legs From Here to Homeworld", pieces of the ship appear scattered across the beach in front of the temple.
By raising her left arm in front of her with her fingers spread, Blue Diamond can make her ship rise from its resting state. After the palanquin enters, the ship makes a fist and then flies to its destination at light speed, causing any nearby clouds to distort its shape; the ship bends in a circular pattern when flying. When the ship flies away, it also appears to create a strong blast of wind in the opposite direction, as seen when it stops Steven's floating abilities.

Yellow Diamond's Ship
Yellow Diamond's Ship is a massive yellow right arm-shaped spaceship. The ship was owned by Yellow Diamond until it was destroyed.
Throughout the ship's arm and hand, dark yellow lines are present and create square shapes in different parts of the exterior. There is a small hole on the ship's palm. At the end of the arm, there is a yellow rectangle.
In "That Will Be All", the ship makes its first appearance at the zoo when Steven, Greg, and the Crystal Gems are leaving in the Roaming Eye. In "Reunited", Blue and Yellow Diamond come to Earth in their ships to release The Cluster. The ship is destroyed when The Cluster throws Yellow Diamond's ship onto Blue Diamond's ship. In "Legs From Here to Homeworld", Yellow Diamond attempts to activate the ship but fails.

Pink Diamond's Ship
Pink Diamond's Ship is a large pink spaceship shaped like a pair of legs and also shaped like heels. Throughout the ship's legs, light pink lines are present and create square shapes in different parts of the exterior.
The interior of the ship is almost circular. The ceiling is pink. The walls are red with the violet-red original symbol of the Great Diamond Authority. The center of the walkway has a footboard to activate the hologram around the legs. In front of the ship, the window frame has the shape of the triangle. Two huge seats flank the walkway. The back doorframe has the shape of the triangle.
In "Lion 4: Alternate Ending", the ship makes its first appearance, abandoned and mostly buried in the desert in front of Rose's Landfill. In "Legs From Here to Homeworld", Steven manages to activate the ship and uses it to go to Homeworld.
When Steven touched the ship with his hand in "Legs From Here to Homeworld", the pedestal and the whole ship glowed and rose out from the sand. In order to launch, the pilot has to get a running start. The pilot's legs control every movement of the ship. A holographic panel can be accessed near the footboard, presumably functioning as a dashboard. Like the Gem Warship, Pink Diamond's Ship can generate bubbles that can engulf its occupants and pass through its walls, allowing for rapid transport in and out of the craft.
White Diamond's Ship
White Diamond's Ship is a massive white head-and-torso-shaped ship. It is owned by White Diamond. The interior of the head part of the ship is shaped like an oval. The walls are whitish gray.
It made its debut in "The Trial" and appeared in the title cards of "Off Colors", "Lars' Head", "Familiar" and "Together Alone". In "Legs From Here to Homeworld", at the Diamond Ship Docking Bay, White Pearl transports Steven directly to White Diamond's ship, where he meets White Diamond. The ship has remained docked at the same location since. In "Familiar", Steven looks at the ship from his mother's old room at night. In "Together Alone", it still appears. In Escapism, Stevonnie looks outside of the window of the Prison Tower at the city, the view including White Diamond's ship.
- Blue and Yellow Diamond's ships resemble the Gem Warship in shape, except that each of their ships includes an arm attached to the hand and are colored to match their owners.
- All the Diamonds' ships make up the parts of a complete body and have the same colored pattern as the Authority's symbol. They are designed to join together, as shown in "Change Your Mind".
- As seen in "That Will Be All", Blue Diamond's ship is in the configuration of an outstretched hand, while Yellow Diamond's ship is in the configuration of an enclosed fist. This shows Blue and Yellow Diamond's personalities; Blue Diamond is more understanding and willing to help and listen, whereas Yellow Diamond uses force to get what she wants and is more strong-willed.
- While Pink Diamond's ship made its debut in "Lion 4: Alternate Ending", it was not identified as such until "Legs From Here to Homeworld".
