Easy junk
for easy minerals, Fossils and cheap cubes just go to daichi and keep using a child Spectrobe for the searching. Each child has a different range of radar (you can see it when you wake them up, it’s in the top right corner of the top screen) the small range usually gives you mostly fossils, the larger mostly minerals, all ranges give you cubes. You can try this on all planets.
Pearl mineral can be found on the planet Nessa area two. Go through two gates of four grey pillars and on the far side of a none moving vortex, search for a mineral. It has 3 balls fused together and is worth 10,000gura.
Diamond mineral is on table top Mt. on daichi, there are ray’s (purple pillars in the area) that zap you and take away your energy. To avoid them go to the equipment mangier on kollin (headquarters) buy the red suit , it stops the zapping. When you get to the top you have to fight a HUGE Krawl, its first moves is a slash of its arm, dodge it and your good. The second is a spin towards you, when he stops attack with a spectrobe, his third move is a pound to the ground, DON’T GET IN FRONT OF HIM! If you do a red spots on the ground hit you, I don’t know anything else on him (I get him before his third move, cause I have two Lv118 Inkafalre Auger’s! 
) after you beat him and talk to Jenna search for the mineral under were the Krawl first showed up! Then you got the diamond minneral.
Inkaflare (Inkafalre Auger just has a drill for arms, I got it in a cheat card.) you can find the child (inkana) form on Genshi Area 2.
