I think it will definitily be explained in the later Arcs, maybe when Dr. Vegapunk will appear in the manga.

@pap I think I read somewhere that Oda said *a New World scientist* would appear and tell us more about Devil Fruits soon. Maybe at the end of the current arc? He might also tells us more about seaprism as well.

Note that you can sometimes abrasion cut a very hard material with its own dust. This also says nothing about whether the material may be brittle or chemically active.  Very hard materials are easy to fracture and diamonds can easily heated into CO2.

If they were just hard as diamond, Zoro could have cut them (Alabasta arc). Note that not even the bird cage or Franky's beam did any harm to the Sea-Pism coated factory. Since they are SEA-Prisom stone, they may be formable in sea water.
