What Are and How Natural Diamonds Occur
Diamonds Colorless = grow in an octahedron direction of the crystal lattice growth, they likely contain no nitrogen nor boron.
Natural diamonds are estimated to take 1 billion to 3.5 billion years as that is how there dates are tested currently and they travel through earths highways from the earths core into the subsection zones, volcanic vents, hydro dynamics, hydraulic fracturing, then rising up through volcanic pipes and moving as well up through the Lithosphere layer of the earth.
What are Earth created or natural carbon diamonds?
Diamond is made of the element symbol C Carbon, atomic number 6. Carbon is a black element that under pressure and very high heat for billions of years can form a diamond and that is how the natural diamond is made.
The diamond is one tough mineral. Diamond atoms are arranged in a crystal structure called diamond cubic, this arrangement of atoms in the diamond structure are very rigid.
What a diamond is made of was first confirmed, but was not the first discovery to be made of 100% carbon in 1797, however it was discovered in 1772 by a French scientist Antoine Lavoisier who utilized a lens concentrating the suns rays onto a diamond in an atmosphere of oxygen and this showed the only thing combusting was carbon dioxide and this was the proof that the diamond is made 100% of Carbon C it has become one of many humans quest utilizing this gained knowledge to venture outward to pursue knowledge and then produce these highly sought after gems in a human built controlled environment, this has been achieved in its latest and most stable form the laboratory diamond.
The diamond mineral is a very clean and clear of impurities native mineral, because carbon under super high pressure along with super high temperature applied for millions and billions of years very deep within the earth means very few, in fact only two well known elements from the periodic table can be found in trace amounts in a diamond and they are in lighter trace amounts.
Though still rare there are these two more common elements, they are atomic number 7 Symbol N color yellow representing nitrogen and atomic number 5 Symbol B color blue representing boron.
Diamonds do attract other single elements, creating other natural Diamonds Fancy Colored ones, they are however very very rare.
Diamond is toughest natural material on earth
There are tougher synthetic materials and formulations that compete with that toughest spot on earth category, but as far as being the toughest natural mineral element or substance, the diamond is the currently known leader.
The diamond is a 10 on the Mohs Mineral Hardness Scale for hardness on this scale there is no harder natural material.
The Mohs tests created by Friedrich Mohs in 1812 relies on the scratch test that a harder material can scratch a softer material and based on that test result the mineral Talc being the softest mineral and diamond being the toughest mineral, There are 8 others that are within the middle of the scale, the test is quite reliable for a field test of most all minerals. Any mineral under a 2 Mohs can be scratched using your finger nail.
