Both Luke (for his green saber) and Jiana grew their own crystals while meditating on them to remove impurities and imbue it with the force. That's also how the Sith make red lightsaber crystals. That's what my guy's going to do to make his.Also, in KOTOR 2 you get a personal crystal from the crystal caves on Dantooine (where at least one person will be sent when they are ready for their trials), but it isn't a primary crystal. According to a quote on Wookipedia, most crystals can be used, they just have to be attuned to the force and free from impurities. The reason they use crystals from Illum is because they are very pure and are naturally tuned to the force. We can go there, if you want, though.

Sith Lightsabers are typically red because artificial crystals are generically red. Luke using this as training for his Padawans as they need to concentrate with the Force to make the colour of the crystal one they want.

Also sorry not in the zone to right tonight, what was the verdict on the dual phase lightsaber btw?
