The Shiny Gem Warehouse was the Barzini's diamond and jewellery warehouse, where illegal goods were shipped around after passing through the Barzini Hub in Mid Town. Ruled over by Simon Fletcher and Victor Barzini, it was heavily guarded and hidden to the east of France, away from the prying eyes of the police. The Barzinis however, now lead by Paul Fortunato, were able to retake the Gem Warehouse after a long shootout in February, 2014.
