What is Natural Rough Diamond?


The Very Difficult & Durable Material is referred to as the Natural Rough Diamond.

  • It gets for the Amazing Brilliance.
  • It appears to be sparkled.


It Contains Carbon

Element Carbon is found inside it. So there will be Carbon in its Pure Form in the Core of Natural Rough Diamond. Rough Diamond is having the Meta Stable Allotrope of the Carbon. In this Allotrope, the Carbon Atoms are arranged in the Face Centred Cubic Crystal Structure Variation. And overall this Structure is widely known as the Natural Rough Diamond Lattice.


Compare to Graphite

However, the Natural Rough Diamond seems to be lesser stable compare to that of the Graphite. (Graphite also gets the Allotrope of Carbon Structure)


Optical Distribution

Natural Rough Diamond is known as a Gemstone because of having for the Higher Optical Distribution. It gets for the ability to distribute for the Light of Different Colours in a way.


Impurities & Colour Specifics

It also gets for the Greatest & Stiff Lattice. Thereby, the Impurities (like Boron or Nitrogen) inside are very low. This Small Amount of Impurities is reason for its Colour. The impurities are accountable as 1 Per Million of the Lattice Atoms.

  • Boron makes it appears as blue.
  • Nitrogen makes it appears as yellow.
  • Lattice Effects makes it appears as Brown.
  • Radiation Exposure makes it appears as Green.



Back in 800 BC the Natural Rough Diamond was found in India. It was holding for the Holy Power Attributes. Even there was a belief not to alter it as altering would lessen its strength. So it was worn by people just in its original appearance. Likewise, the Powerful Energy was preserved in the Ancient Era.


Royal Use

Sometimes it is Transparent and at the same time being flawless as well. Thus, Natural Rough Diamonds are much Precious Stone. They are in fact so unusual to be found in the oldest time so only Royals used to own them.





How does Natural Rough Diamond Formed inside Earth?


It took almost Billions of Years in order for the Formation of the Natural Rough Diamonds.


The Process

It was thus a result of the Intense Heat & the Pressure. Due to Volcanic Eruption, Natural Rough Diamond Bearing Ore was brought to the Surface of the Earth. Times later when Magma was being cooled off it was converted into the Blue Ground, pretty much known as Kimberlite. This is the Place where in the date as well most of the Precious Natural Rough Diamonds are found.


Required Temperature & Pressure

Carbon gets crystallized because of the Exposure into High Temperature & Pressure, It than forms for the Natural Rough Diamond.

  • The Temperature has to be around 900 to 1300 °C.
  • The Pressure has to be around 45 to 60 Kilo Bars.


Age of the Natural Rough Diamond

It was formed way back before the Dinosaurs Era on the earth. Thereby each & Every Natural Rough Diamond is Very Much Old.

  • The Age of the Oldest Natural Rough Diamond is 3.2 Billion Years.
  • The Age of the Youngest Natural Diamond is 900 Million Years.


How it became Inventive Rock

It is formed at the Depths of around 140 to 190 Kilometres of the Earth under the lot of Pressure & Temperature. It sourced the Carbon from the Carbon Containing Minerals. It takes around 1 to 3.3 Billion Years (which is 25 to 75% of the Earth Age) for the Growth of the Natural Rough Diamonds. Due to a Deep Volcanic Eruption it came onto the Surface of the Earth. Afterwards it cooled down into the Inventive Rock, now known as Kimberlitic & Lamproites.





Physical & Chemical Properties of the Natural Rough Diamond


Compare to Any other Bulk Material, the Natural Rough Diamond gets for the biggest Hardness & Thermal Conductivity.


The Hardness & the Purity

The Hardness Number of the Natural Rough Diamond is 10 Mohs. The Pure Form of the Carbon is the Natural Rough Diamond as a whole. The Carbon Atoms in the Natural Rough Diamond are typically found in Octahedral Lattice & Covalent Bond. Because of their Hardness, the Faces of the Natural Rough Diamond Octahedrons are mostly shiny.



Mostly it is available in No Colour or in Yellow or in Brown. The Colours like Pink or Blue or Green or Gray or Orange or Red are pretty rare. However, the Natural Rough Diamonds occurred to have different colours as below.

  • Black
  • Brown
  • Yellow
  • Gray

  • Red

The Colourful Natural Rough Diamonds are having below things.

  • Crystallographic
  • Substitution of Impurities
  • Structural Defects (that is responsible for Specific Colour)

The Transparent or Colourless Natural Rough Diamonds are referred as Pure. Scientifically speaking; with respect to the Present Nature of Defect & its effect to the Light Absorption, it gets for 2 Main Types & Several other Sub Types.


Crystal Shape

  • Octahedral
  • Cubo Octahedral
  • Spherical
  • Cubic


Specific Gravity

  • 516 to 3.525


Refractive Index

  • -2.417



  • It Burns above the 700 °C in the Air



Thermal Conductivity

It gets for the 22 W/ (Cm * K) Thermal Conductivity which is almost 5 times higher than that of Copper.
