How are diamond formed: how are diamonds polished and cut

Diamonds, There will be no one who does not know this name. Most of us would thought of buying a diamond ring or a diamond chain. Let's us know How are diamond formed
Diamonds are so valuable that you can buy a street or village with some diamonds.
Read this article to know information on diamonds and how diamonds formed?, how are diamonds mined? And how Diamonds are polished? 
Diamonds are made up of carbon, so diamonds form as carbon atoms.
How are diamond formed

Unlike ordinary stones, carbon atoms in diamonds are arranged in a cubic crystal structure is known as crystal structure or lattice structure.
That's why diamonds are unique than other Stones.
Now, Let us learn

How are Diamond Formed ? 

Many among us thought diamonds are formed from the coal and have doubts such as how long does it take for coal to become a diamond?
But, After carbon dating researchers found that
Diamonds were formed 1 to 3 hundred billion years ago.
But the interesting fact was at that time there were no trees on earth.
We know that coal is formed when dead trees accumulate on the ground.
So diamonds are not formed from coal.

Earth consists of four main layers, namely know as the crust, mantle, outer core, and inner core.
Diamonds can be found from the range 150 km to 250 km from earth's surface to the outer core of earth technically it is known as Earth Mantle.
According to researchers

300 billion years ago, Diamonds were formed due to carbon fluids present in the earth Mantle under high temperature and pressure in the earth mantle.

The formation of some colour diamond's( How are Diamond formed )

In Fact, Diamonds are colourless
But, In some rare cases colour Diamonds are formed

Formation of blue Diamond's 

Consider a diamond consist of 10 lakhs, carbon atoms with a boron atom, then a blue coloured diamond is formed.

Formation of Yellow Diamond's 

Consider a diamond consist of 10 lakhs, carbon atoms with a Nitrogen atom, then a yellow coloured diamond is formed

Formation of Brown Diamond's 

If the structure of carbon atoms in diamonds is not formed properly, then a brown coloured diamond is formed

Formation of Green Diamond's 

In case, If the intensity of radiation on the diamond is high, then a green coloured diamond is formed.
Formation of colour diamond are rare.
I think you understood how are diamond formed.

How Diamonds are out from earth( How are diamond formed )

Diamonds bury in the earth from 150 km to 250 km or even deeper inside the earth.
A few thousand to millions of years ago due to Deep Source Volcanic Eruption the diamonds are out from the earth.
Lamproite and kimberlite magma, which is about 300 km below the earth, it is simply known as magma.
Due to the Deep Source Volcanic Eruption, this magma rises to the earth's surface with speed 250 km/h with diamonds.
Deep Source Volcanic Eruption occurs rarely.
Since it is the time of the modern period, there is not even a single Deep Source Volcanic Eruption.
But the General Volcanic explosions take place every year, causing the diamonds to come to Earth Surface.
In this way we are mining and extracting the diamond from the earth's surface, but diamonds at 200 km or even deeper are something we can't recover.
So far we have unable to Dig more than 12 km, So It is not possible to dig hundreds of kilometres to recover diamonds.
Diamonds are rare to find, According to estimation of some researchers.
We dug approx 1 lakh 75 tons of gold, but when gold is compared to diamonds we only got 500 tons of diamonds till now.
Now let's see

How to find diamonds?

(where are diamonds found)

We already learned that when Deep Source Volcanic Eruption occurs, kimberlite magma comes to Earth's surface with diamonds.
This magma surrounds the Volcano from all sides.
However, when the kimberlite magma enters the Atmosphere (earth surface), it turns as the kimberlite Stones.
This means that diamonds are located where the Kimberlite Stones are located.

How are diamonds mined? 

There are three ways to recover diamonds

PIPE MINING

There are two main types of pipe mining, namely called as
1. open-pit mining
2. underground mining

Open-pit mining involves expelling the layers of sand and rock discovered simply over the kimberlite. When uncovered, the ore in the pit is separated by impacting (blast). A solitary impact (strong blast) can break approx 3,000 tons of minerals (ores). When the metal (ore) is broken, excavators load the metal (ore) into pull trucks and transport it to an essential metal (ore) smasher where the jewel removing process starts. The Kimberley Large Gap is a case of open-pit mining.

In underground mining, excavators burrow through the Earth's crust to the kimberlite pipe. Passages (tunnels) are developed on two levels, one over the other with channels (funnels) worked to interface the two. Mining starts at the top level by impacting metal (blasting ore), which falls through the channels (funnels) and gathers (collect) on the 2nd tunnel. Here, loaders gather the crushed mineral (ore) and carry ore to the surface for preparing.

ALLUVIAL MINING

Over thousands of years, the kimberlite pipe that reaches the Earth’s surface is worn and worn by wind, rain, rivers and streams.The worn kimberlite bears rough diamonds, that kimberlite rocks and stones carried downstream. The primary diamonds discovered in African nation were from alluvial deposits.
Today, mechanical alluvial mining includes building a huge divider to gather the water in one territory. Diamonds are regularly found in the rock layer (gravel layer), which gathers under layers of other material, for example, mud, clay and submerged vegetation (underwater plant life). When the rock is gathered, it is pulled to the surface and arranged for processing.

MARINE MINING

Marine mining includes separating precious stones (diamonds) from the seabed, many meters submerged under water. The earliest type of marine mining involved shore jumping, where a swimmer would gather precious stone bearing rock from the shallow seabed. Today innovation has advanced to particular ships that dig for diamonds located deep under water. These particular boats utilize an amazing crawler that sucks rough stones (kimberlite stones) on the seabed up through adaptable hoses/pipes. Then again, they utilize an enormous scope drill mounted to the boat to excavate diamonds.
The sea bank of Namibia is the most richest precious stone deposits (diamonds). Around 64% of Namibia's total jewel (diamonds) production.

How diamonds are polished 

Before we rush to know how diamonds are polished, we need to know an important thing
All the diamonds we see are cut and polished.
The one who cuts and polishes gems are called as lapidary.
Some designs are shown below

Diamonds are in the form of rough stones when they are recovered from earth, after polishing this rough Stones makes them an excellent diamond.
Here comes the importance of planning
This plan includes
How many Diamonds can be produced from a single rough Stone?
And
How to design them?
These types of queries (measurements) are calculated in computer's for better results.

These rough stones (Diamonds) later cut (Cleaving) into small pieces with diamond sawing machine this process is known as Diamond Cleaving or sawing.

Now these pieces (Diamonds) are bruting with a diamond bruting machine this process is known as Diamond Bruting.
Do you know
What Are Diamonds
Diamonds are naturally formed hardest material in whole world.
Diamond is sixth hardest material on earth till now and 1st place in Naturally formed hardest material.
To cut a diamond the tools must be stronger than it, That's why diamonds are cutted with another diamond.
In this process lapidary ensure that the diamonds must have at least 57 to 58 facets.
Facets are also known as sides.
However, the diamond will be polished once it reaches their proper shapes.
Diamonds appear to shiny from all angles after polishing.
Lastly, Diamond are inspected to ensure

Whether the Quality, Measurements and other specifications of diamonds are correct as the Manufacturer said
India is ranked number one among the countries in polishing the diamond.
Nearly, 31% of diamonds are polished in India when compared to the whole world.
Do you know
We think diamonds are only used as jewellery but due its hardness diamonds are used for industrial purposes, to cut glass, to polish other stone's and some companies uses diamonds to protect electronic appliances from heat.
