A Borg diamond.
Interior of a Borg diamond.
The Borg Queen's vessel was a unique diamond shaped starship that was used by the Borg Queen to travel. Little is known about its capabilities or specific purpose. However, the only times the diamond has been seen have been to transport the queen, and thus it can be inferred that it is 'her' ship. The ship is heavily armed and well protected and like all Borg ships, capable of transwarp speeds. The ship is approximately 800 meters long.
A Borg Diamond was present when Species 10026 was assimilated. It was assumed that Seven of Nine and the Borg Queen were aboard while this assimilation took place. Later, a Diamond pursued the Delta Flyer when it escaped from the Unicomplex after rescuing Seven. The Diamond was destroyed when the USS Voyager collapsed the transwarp conduit it was traveling in.

- The designation "Borg diamond" is never mentioned on screen, but is ascertained by its shape. It is, however, designated the Borg diamond in the game Star Trek Armada as well as many other games. It remains unknown whether any other ships of this type exist.
