Diamonds are formed by Mother Nature, deep within the Earth's mantel over millions of years. Once mined from the ground, the raw diamond is cut, shaped and polished by a professional diamond cutter using diamond cutting tools -- the only hand-made process for this gemstone.
Note that diamonds can also be formed in labs, from carbon. These are not 'hand-made' in the strictest sense of 'hand-made', but are also cut, shaped and polished by a professional diamond cutter.
Diamonds are mined depending on how the diamonds are present in the earth's surface.
Open-pit mining around the volcanic pipes is common. Mined material is dynamited, crushed and moved to a plant where washing deposits diamond-containing residue in separate areas.
Diamonds can also be found in riverbeds, at the mouths of rivers and in the sea-bed having been washed along by water running over a volcanic pipe that contains diamonds. These areas are similarly stripped of material and washed, delivering the diamond material to a separate area.
They are essentially compressed carbon; when the carbon is at a very high temperature and under very high pressure, the bonds are formed. Natural diamonds are made 180km below the earth’s surface. The temperatures at this depth are between 1100o c and 1400o c. Diamonds rank 10 (the highest) on the Mohs scale, range from transparent to opaque and is not affected by any chemicals.
A diamond is made of carbon that is formed underground and under pressure to produce the diamond. Other elements are also involved so they are different colors and can have various flaws.
a diamond is mined from the ground using a special tool which is a big drill or in some countries they are dug up by hand in mines.
take 7 good pics of different animals then he will give u a hard hat cutebunny
Diamonds are mined, they are not harvested.
There are no productive diamond mines in USA.
Diamond mines are used for mining diamonds.
there is no magnifing glass in diamond mines!
The diamond with the symbol on it.
Yes, there are gold mines and yes, there are diamond mines. The two resources have not been mined from the same mine.
Found in the mines of India.
You go to Big Zeke in the Safari and go through the Diamond Mines.

Yes it does.
There are no significant diamond mines in Egypt, certainly none in Cairo.
Diamond mines are typically found in countries with rich deposits of diamond-bearing rock, such as Botswana, Russia, Canada, and Australia. In these countries, diamond mining operations extract diamonds from deep underground or from alluvial deposits in river beds.
Diamond mines are formed by mankind using earth movers, dynamite, and other mining techniques. Diamond mines are dug around volcanic pipes which erupt bringing diamonds closer to the earth's surface.
