Diamond is the hardest naturally occurring mineral, topping Mohs’ Scale of Hardness with a relative hardness value of 10. Diamond is a polymorph of the element carbon, and graphite is another.
Is Diamond a mineral or not?
Diamond, a mineral composed of pure carbon. It is the hardest naturally occurring substance known; it is also the most popular gemstone. Because of their extreme hardness, diamonds have a number of important industrial applications.
Why Diamond is not a mineral?
Diamonds, on the other hand, are formed in the Earth through chemical reactions with no organisms involved, making them inorganic. A mineral is solid. … Diamonds are made entirely of carbon so they easily fall into this category. A mineral has an ordered internal structure.
Is a mineral solid yes or no?
Once again, a mineral is a naturally occurring inorganic solid, with a definite chemical composition, and an ordered atomic arrangement!
Which is not a mineral?
Steel is not a mineral because it is an alloy produced by people. “Inorganic” means that the substance is not made by an organism. Wood and pearls are made by organisms and thus are not minerals. … For example: the mineral halite (known as “rock salt” when it is mined) has a chemical composition of NaCl.
Why is diamond so expensive?
A diamond is the hardest material on the earth and the most expensive gemstone as well. Diamonds are not rare but high-quality diamonds that can be used in the jewelry are rare. … In addition, the size and quality of the diamond also plays a major role on the price. These are the reasons why diamonds are so expensive.

How deep can you find diamonds?
Natural diamonds typically form 150–200 km below the surface of the earth. Diamond formation does not occur everywhere at these depths, but only below the oldest continents that have been stable for billions of years; these areas are known as cratons (see figure 2 in Summer 2018 Diamonds from the Deep).
How can you tell if a rock is a diamond?
Test Hardness:
The only hardness test that will identify a diamond is scratching corundum. Corundum, which includes all rubys and sapphires, is 9 on the hardiness scale. If your suspected diamond crystal can scratch corundum, then there is a good chance that you found a diamond.
Where is Diamond found?
The following countries produce industrial grade diamonds: Australia, Botswana, Brazil, China, Congo, Russia and South Africa. Geologically speaking, natural diamonds are found in two environments. Most are found in kimberlites, which are pipe-like formations created as a result of volcanic and tectonic activity.
What mineral is the hardest?
