diamonds are the HARDEST naturally occuring substance on earth. However they are not the most INDESTRUCTABLE: diamonds can sometimes shatter with only a relatively small amount of force - it is the ability to control the application of this force that allows experts to "cut" diamonds into gem stones.

Hardness - Hardness is the measure of how resistant solid matter is to various kinds of permanent shape change when a force is applied. TL;DR: Which element scratches another.
Strength - Strength of materials is a subject in materials science dealing with the ability of objects to withstand stresses without failure. TL;DR: Which element breaks faster under pressure, etc.
