It is very easy to differentiate between diamond and steel. They have a completely different appearance, and a completely different chemical composition, and very different physical properties. I don't think that anyone gets these things confused.
Triangle..
There are no 'marks' used to differentiate between real diamonds and fake diamonds.
Diamond is harder than steel: you can scratch steel with a diamond, but steel will not scratch a diamond.
Yes. Actually... a diamond is NOT 'stronger' than steel. A diamond is 'harder' than steel, but it is not stronger.

Metals have different colors, different textures, different luster, different melting points and different electronegativities. I will have to conclude that an octopus would be able to distinguish among these properties. It may not be able to tell you what grade of stainless steel you present but, I contend that it will be able to differentiate between mercury and steel. If that be proven, my contention is likewise proven.

It is steel that has raised sections shaped almost like a diamond making it skid-proof.
