The mineral is graphite.
Aragonite is a carbonate mineral it is a polymorph of the more common mineral calcite, it is mainly found in animal's shells.
Some minerals are hard yet some are soft. Talc is the softest mineral as diamond is the hardest mineral. You can look at this on the hardness scale. It goes from one to ten, so talc is one as diamond is ten.
No, a mineral is a hard substance
The mineral is carbon: allotropes include diamond, graphite and coal.
For example talc is very soft.
Diamond is a polymorph of graphite (which are both allotrope's of carbon). Please see the related links.
Diamond is the hardest mineral on earth.
Diamond is the hardest mineral on earth.

calcite-is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCo3). diamond-is pure crystalline carbon(C).
Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO3).
Graphite is a very soft mineral beginning with "g". Interestingly enough, it is composed of carbon, just like diamond, which is the hardest mineral known!

No, diamond is the hardest known mineral, an allotrope of carbon, with a strong crystalline structure.
Well, diamond is a mineral so it isn't any type of rock.Diamond is the hardest mineral on earth and a 10 on the 1-10 MOHZ hardness scale. It is 40-50 times harder than the next hardest rock, corundum which is 9 on the scale. So no, diamond is quite the very opposite of soft, and as previously stated, it is a mineral, not a rock.No, diamond is the hardest rock.
It depends on how soft the mineral is. For example, Talc is the softest mineral. You can scratch it with just a fingernail. but on the other hand, Diamond, the hardest mineral can only be scratched with another Diamond. So as long as you are not trying to scratch a diamond (it would be 50/ 50 change of scratching if use another diamond), use a diamond. NOTE: how easy it is to scratch a mineral has nothing to do with how easy it is to break a mineral. Example diamond is the hardest mineral but can be chipped or broken by a good strong hammer stroke.
No. Quartz is harder than steel (based on the Mohs scale of mineral hardness), and diamond is THE hardest mineral.
