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.
