Aside from using it to obtain your Psychometry weapons it also acts like any other mineral. You can use it to customize your weapons or craft accessories from it (including the Force Booster ring, which doubles your INT - very useful).

Personally, I think the "Blue Sphere" referenced in the title is actually the planet Edifice. There's nothing particularly special about the mineral.
