Gems known as fire rubies held significant worth in the initial years of the Galactic Empire. In the Lothal year 3272, Ezra Bridger, a street urchin and skilled thief, pilfered a fire ruby from the Imperial pavilion area within Capital City on the planet Lothal. Subsequently, Bridger documented this acquisition in his journal, speculating that the gemstone was likely counterfeit.
The initial reference to fire rubies appeared in Rebel Journal by Ezra Bridger, a reference book authored by Daniel Wallace and published in 2014.
