The Diamond was a merchant JumpShip with a Free Worlds League registry. Its type is unspecified, though it had at least three docking hardpoints and implicitly yet more, suggesting it to be a Star Lord-class vessel.
On 2 March 3031 the Diamond was done recharging its drive at the Andarmax system's nadir jump point and had already furled its jump sail but was waiting for the arrival of a final cargo DropShip in about half a day before jumping out. It was scheduled to jump to Turin via Jacomarie, with a DropShip load including a Monarch-class vessel and a modified gas tanker of unspecified type. Cultists traveling on the latter DropShip carried Richard Humphreys with them, who was rescued in a shootout that also caused a fire on the DropShip which was however brought under control quickly. Emma Centrella personally redacted the Diamond's jump clearance until a shuttle arrived that would bring her and Richard Humphreys, among others, back to Andarmax.
The Diamond only is featured in the German novel Gier which, being a German language publication that was not translated into English so far, does not meet the current criteria for canonical BattleTech products and must thus be considered apocryphal. As a consequence, the Diamond and all information about it is apocryphal as well.
- Gier, p. 310, mentions that besides the Monarch that just arrived and another DropShip that is expected to arrive within twelve hours, a gas tanker DropShip is already docked. The description of the free docking hardpoint implies there are more than just two occupied at this time.
