Is this adrandite garnet or pyrite? Is this rough stone could be cut for gemstone (I'm afraid it would broke in pieces)?

Tha actual color of the crystal is brown. There is no grey/bluish color in actual stone, maybe it caued by the effect of crystal slope. The crystal is small (3 to 5 mm) but in group.formation.

This is front pict

 

This is from the other side. The actual color of blue in this pict is brown.

Yes it looks like andradite. It is from the garnet group. It is sometimes gem quality. Should not have difficulty cutting these stones.. It is formed in iron bearing rock so I would not be surprised to see andradite and pyrite side by side. Andradite is a calcium iron silicate.
