The first time your there you have to break some statues to find a purple one. The second
time your there you will find a blue crystal near a door next to the left wall. The third
time your there you will find a green crystal near the right wall but it will be hard to
find. An easy way to remember all this is that there all in the same place at the jedi
temple just not at the same time.

there is blue one by elvoter last one.

the black lightsaber in in I think it is the third or fifth level, but it is the first
time you go to the Jedi Temple. to the left of the entrance to the temple, there is some
crumbling remains (this is still on the outside), if you use lightning force, you will
notice there is a section un-affected by the light, try to blow it up however you can
(explosive, force push+lightning from a distance). the black lightsaber crystal might
unlock all of the colors along with itself

The black saberis for the 360 and PS3 dumbass
