GemDiver Station GemDiver Station was a space station that orbited the planet Yavin . It was constructed in 23 ABY by Lando Calrissian as a Corusca mining operation . Though there were previous space stations like it , GemDiver Station was the only operation of its kind at the time it was constructed , because financing such an operation was initially extremely expensive . Yavin was also the only planet where Corusca gems could be found . Atmosphere . Despite its industrial nature , GemDiver Station ' s interior attempted to be pleasing to aesthetic sensibilities . The walls of the station were painted with soft pastels and were decorated with optical tubes that had been shaped into various designs . Additionally , sounds that occurred in nature were continuously played over the intercom , even during emergencies . It ' s likely that Calrissian intended to generate a " peaceful " atmosphere in GemDiver Station as a counterpoint to the chaotic storms of Yavin . Upper levels and control bridge . The upper levels of GemDiver Station housed the control bridge , offices , and docking bays . The upper observation protruded from the main body of GemDiver Station . It housed the station ' s control bridge , from which command of the station ' s various functions was maintained . The bridge had an all - encompassing view , which was only somewhat abridged by narrow rectangular viewports . The deck of the control bridge contained a sealed armor case which held blasters for use in case of an emergency . Corusca gem mining . GemDiver Station orbited Yavin as close as was safely possible to facilitate its Corusca gem mining activities . As a result of its proximity , the station was double - hulled . The lower levels ( also known as the security level ) housed its mining and shipping operations . GemDiver Station utilized " Fast Hand " , a Submersible Mining Environment to mine Corusca gems in the lower reaches of the atmosphere of Yavin . The size of the gems had a positive correlation with the depth of the atmosphere . However , so did the strength of the Yavin ' s atmospheric storms , so in addition to having a thin sheet of quantum - crystalline armor , " Fast Hand " was also attached at all times to GemDiver Station by an energy tether . Calrissian employed a number of contractors known as corusca fishermen to mine the upper atmosphere of Yavin as well . Calrissian supported their operations in return for a percentage of what they caught . Despite the fact that they would only find smaller Corusca gems and Corusca dust there , he still considered it well worth the effort because even Corusca dust had a good value . Shipping . In the shipping chamber of GemDiver Station , copper - colored , multi - armed droids would pack newly mined gems into automated cargo pod s . Once they were packed , the pods were sent to Calrissian ' s broker on Borgo Prime . The broker sold them and collected a small percentage of the profit . Had he not been dealing in Corusca gems , Calrissian ' s broker would have demanded a higher percentage , but the extremely high value of the gems helped Calrissian get him to settle for less . However , like many other brokers , Calrissian ' s broker was usually unwilling to divulge the identity of the people whom he was selling to , fearing that he ' d lose his status as a middleman . He was not immune to bribes , however . Security . Because of the high value of Corusca gems and the financial risk involved in mining them , Calrissian placed a premium on security in his operation . In addition to armed security personnel , he took a number of additional measures to protect GemDiver Station in case of an attack . Before even docking with the station , a ship needed to pass through a perimeter of dozens of automated defensive satellites . Every ship that approached the station was greeted with the sight of the satellites powering up their weapons and training their weapons on the possible intruder . If the ship did not broadcast an access authorization code , the satellites would attack it . The security level , where the shipping and mining operations were housed , was guarded by heavy , armored triple doors , which would only open with a person who had the correct code clearance . Droids were the only personnel which loaded the automated cargo pods , which were equipped with self - targeting lasers . Despite all the security measures that Calrissian had put in place , they were proven to be useless during the Second Imperium ' s Raid on GemDiver Station . The perimeter of defensive satellites proved to be insufficient to deal with the ion cannons and lasers of four GAT - 12 Skipray Blastboat s . The double - armored hull was breached by a modified Imperial Assault Shuttle sporting industrial grade Corusca gems , which somewhat ironically , had been mined at GemDiver Station . The doors guarding the shipping chamber were breached by a heavy - duty laser . Additionally , the protestations emitted by one of the packing droids did not prevent it from being gratuitously blasted into scrap by a stormtrooper . In the aftermath of the raid by the Second Imperium , Calrissian and his cyborg assistant Lobot attempted to find ways to improve GemDiver Station ' s security , one of which involved Corusca gems in some way . It is not known what the rest of these were , nor whether any of them were implemented .
