Diamond and also graphite are chemically the same; both are carbon. However, they have entirely different atomic and also crystal frameworks. Diamond atoms have a rigid 3-dimensional structure, with each atom carefully loaded with each other as well as connected to 4 other carbon atoms.

The factor for the differences in firmness as well as various other physical homes, can be explained with the molecular versions listed below.

Both Diamond and Graphite are crystalline carbon (both are pure carbon).

What are Diamonds?

Diamond is a kind of carbon that takes shape in the crystal system of greatest symmetry, referred to as the cubic system born thousands of miles below the earth’s surface area. Diamonds are created after countless years under heat and great pressure. They are brought to the surface area through a volcanic eruption. A diamond that is naturally created under the earth’s crust is referred to as  Rеаl Diаmоndѕ. Man has found out the process of diamond development and also has efficiently produced man-made diamonds in laboratories. They are referred to as ѕуnthеtiс diamonds.

A diamond is an allotrope, or a type, of the aspect carbon (it is carbon in its most concentrated kind). Within the precious stone, the carbon atoms are arranged in a variant of the face-centered cubic crystal structure called a diamond latticework. This arrangement of carbon atoms implies that the diamond broadens externally at the same rate in all instructions during its initial growth.

Because of its structure, which is extremely inflexible, a diamond could be infected by very few contaminations, such as the elements boron or nitrogen. Integrated with its tendency to be clear, this causes most diamonds' anemic, clear appearance. Blue diamonds come from boron pollutants, yellow from nitrogen contamination, brownish from latticework defects, and environment-friendly diamonds from direct radiation exposure.

Diamonds have a hardness far surpassing compared to any other substance understood to us. It has a very high openness and dispersion or 'fire.’ If diamonds are offered a really good cut, it provides a high degree of brilliance and a screen of colorful shades. As a result of its hardness, diamonds used for industrial purposes and gem quality once are cut into gems.

What is Graphite?

Graphite is a non-metal. It iѕ also аn allotropes of саrbоn ѕuсh аѕ diаmоnd and fullеrеnе. It iѕ soft аnd slippery as it iѕ аrrаngеd in lауеrѕ whiсh аrе hеld bу wеаk Vаn der wааlѕ—every layer iѕ оnlу оnе-аtоm-thiсk.

It саn аlѕо соnduсt еlесtriсitу аѕ every Carbon iѕ only bоndеd tо thrее others, lеаving thе fоurth еlесtrоn free аѕ delocalized еlесtrоn.

Grарhitе iѕ a сrуѕtаllinе fоrm оf carbon, a ѕеmimеtаl, a nаtivе еlеmеnt mineral, and оnе of thе allotropes of carbon. Grарhitе is the most stable form of саrbоn undеr ѕtаndаrd conditions. Thеrеfоrе, it iѕ uѕеd in thеrmосhеmiѕtrу аѕ the standard ѕtаtе fоr defining the heat of fоrmаtiоn оf саrbоn compounds. Grарhitе mау be соnѕidеrеd the highеѕt grаdе оf coal, juѕt above аnthrасitе and alternatively саllеd mеtа-аnthrасitе, аlthоugh it is nоt normally used аѕ fuеl because it iѕ diffiсult tо ignite.

Whаt iѕ the difference between Grарhitе аnd Diаmоnd?

Both Diamond and Graphite are crystalline kinds of carbon (Both are pure carbon). They are the same in their chemical structure; they vary a whole lot in their physical makeup. On the Moh s array, Diamond rates as 10, making it the hardest mineral compared to Graphite, which is the softest. Thus, based on the physical buildings, they are utilized for various functions.

Also, as a result of its rarity, a Diamond is far more expensive than Graphite.

Although they are made from the exact same component (Carbon), a Diamond differs from Graphite in its atomic structure. In Diamonds, the atoms are carefully packed together, with each atom connected to various other carbon atoms, as compared to Graphite, where the bonds between the layers are weak. This is the reason why Diamonds have an extremely solid as well as inflexible framework.

Both are pure carbon, however, vary in crystalline framework because they adhere differently.

A carbon atom has 4 electrons that are unpaired as well as can develop bonds by pairing with electrons from various other atoms. When it comes to diamond and graphite, we are speaking about just various other atoms of carbon.

All the electrons are matched with covalent bonds to other carbon atoms in a diamond. The diamond framework is hard to envision in a 3-dimensional room; however very easy to see in a 3-dimensional version.

In Graphite, 3 of the 4 electrons remain in covalent bonds With three bonds at 120 degrees from each different; another one could make a level framework. Graphite forms flat sheets. Graphite is a lot less thick compared to diamond due to the fact that of the space between the layers.

Diаmоnd аnd graphite саn bе differentiated frоm еасh оthеr in thе following mаnnеr.


  • It is the hardest compound known, and its thickness is 3.5 g/mL.
  • Carbon adhered to four different carbon atoms developing tetrahedrons.
  • Tetrahedrons combine to develop 3-D structures.
  • Does not conduct electricity.
  • It does not have any kind of appeal.
  • It has a very high melting factor.
  • The carbon atoms in the structure are sp3 hybridized.


  • It is a soft and also weak substance with a density 2.3 g/mL.
  • Each carbon atom is joined to three other carbon atoms by strong covalent bonds to develop level hexagonal rings.

Diamond and graphite are chemically the same; both are carbon. Nevertheless, they have completely different atomic as well as crystal structures. In a diamond, the carbon atoms have solid bonds in three measurements, makings it hard. In graphite, the bonds are created in level layers, with carbon atoms having solid bonds on the very same layer with weaker layers above and below, making this graphite weak. Diamond atoms have a rigidthree-dimensionall framework with each atom closely compacted as well as attached to 4 other carbon atoms. Literally, diamonds tend to appear shiny and bright (the expensive ones, anyhow), and graphite has a shabby and black appearance.

Man has discovered the process of diamond formation and has successfully produced synthetic diamonds in research laboratories. A diamond is an allotrope, or a type, of the component carbon (a diamond is a carbon in its most focused kind)Within a diamond; the carbon atoms are prepared in a variant of the face-centered cubic crystal framework called a ruby latticework. Blue diamonds originated from boron toxins, yellow diamonds from nitrogen pollutants, brown diamonds from latticework troubles, and environment-friendly diamonds from radiation direct exposure.
