The difference between normal dirt and a stain is in their difficult to wash off. Normal dirt comes off easily but a stain is a colored patch which penetrative and thus making it hard to remove.

Easy- spikes come Normal- enimies come Hard- less rings Very hard- clear spots come P.S. Very hard is the farthest I've gotten
The difference between a real diamond and a false diamond is hard to tell from appearance. But experts can determine the validity of the diamond by a magnified scope. This scope can extinguish the difference between the two by the color and density.
Diamonds are very hard, and graphite is very soft.

There are several differences, the primary one being that on the Mohs hardness scale, diamond is 10, quartz is 8. Quartz crystal is very hard, but diamond is harder.
Diorite is an extremely hard rock, making it difficult to carve and work with but not anywhere near as hard as a diamond
Only Diamond is as hard as diamond, and if their could be any gem stone as hard as diamond then it would definitely be Diamond.
Diamond is the hardest known mineral.
