Lowickan Firegems
the mining, sale, and distribution of these precious minerals was monopolized by the Empire, following the blockade of the Pa'Lowick System. They were known to be found in only one place: the Lowick Asteroid Belt, near the planet Kessel. How or why these unusual gems form is unknown, but they are usually deep red in color and seem to glow from within. The molecular structure of the firegem vibrates constantly, creating a heat source that makes the gems feel warm to the touch. Criminal and terrorist organizations discovered that the vibration of the firegem has an adverse reaction when placed near a hyperdrive reactor, causing the reactor to explode when the ship enters hyperspace. For this reason, they were outlawed during the Old Republic as well as the New Order.
