Osmium vs Diamond

Who is more durable Emma's second mutation, teh diamond form or Colussos organic steel, Osmium?

I know there is not enough showing to gauge Emma's so called diamond form durability so spec is a must, course based on their natural elements properties..

Colossus is more durable.

emma can be shattered

Colossus all the way, and his form isn't really osmium, it resembles osmium and carbon steel.

bingo, beat me to it.

emma is more heat resistant though, and more resistant in temperature extremes in the opposite direction. also, obviously she is more resistant to high pressure.
