So the cocoon in the core could not exist due to pressure being to great in that part of the mantle. Also the mantle is a solid, again due to the pressure it is under, and magma is only formed near the lithosphere. Lastly the Magnetic field created in the earths core is due to the liquid metal of the outer core moving across the solid metal inner core. So no the cocoon in the movie The Core could have it own isolated EM field.
Their's is an uneasy life.
African countries where diamonds are mined depend on this natural resource as a source of employment, tax revenue and generally business development around the industry.
The area on and around a volcano would be a likely place for diamonds to occur, but Mt. Rainier is not known for having diamonds. The closest location to Mt. Rainier is Montana and Canada, somewhat north of Montana. The largest number of diamonds are mined in Russia, but the largest deposit is in Australia. Diamonds were known and used in India perhaps as long as 6,000 years ago.
heck no
Carbon is the element from which Diamond is formed. Just pure carbon. Made deep in the Earth. The hardest substance known (though all diamonds are not equally hard) and rates 10 on the Mohs hardness scale. This is an arbitrary scale. The hardest diamonds come from the NSW fields of Australia, and are in demand as polishing material. Diamonds also have the highest 'melting point' of the elements - around 3820oK. They have the highest thermal conductivity -- about 400 times that of copper. Other allotropes of carbon are charcoal, graphite, and perhaps graphene.
There are thirty five countries around the world where diamonds can be found in the earth. The most notable diamond deposits are found in Africa, so it is possible to buy diamonds from countries other than those found in South America.
Swarovski crystals are a branded type of lead crystal that is made primarily of glass and lead and may also be coated with other materials. When comparing crystals to diamonds, they are commonly referred to as a diamond simulant. Simulants may look similar to a diamond, but do not possess the same properties. A diamond is formed from carbon and has a hardness of 10 on the Mohs scale -- the hardest. Lead crystal is graded around 6-7, though both can scratch glass.
Some diamonds may be included in kimberlite.
Natural diamonds are stones recovered from the area around volcanic pipes where diamonds erupt from below the earth's mantle.
People in many African nations mine for diamonds around the volcanic pipes that erupted the diamonds to the earth's surface.
The geology around the Grater of Diamonds was covered by the surface effects of a volcanic pipe which deposited diamonds and indicator minerals there.
The only resource for natural diamonds are the geologies around volcanic pipes.
Chocolate diamonds ave been around as long as the earth has been around, since that's were they are formed by Mother Nature.
Conflict diamonds or blood diamonds. These diamonds are often used to fund conflict and civil wars in diverse regions around the world.
"Herkimer diamonds", the particularly beautiful clear doubly terminated quartz crystals found around Herkimer, NY, are mostly sold to mineral collectors, tourists, or anybody that wants an amazing piece of natural artwork to grace a shelf. Loose crystals are also quite popular in jewelry making, being easily and quickly turned into attractive pendants. Some are bought by faceters for cutting. They are also sold to sick people, by crooks, for purposes of "crystal healing" and similar nonsense.
Diamonds are found in diamond mines that circulate around volcanic pipes: mined diamonds.As well, diamonds are found under water where the water has washed over volcanic pipes that contain diamonds: alluvial diamonds.
The lustrous, transparent, doubly-terminated quartz crystals from mines around Herkimer, New York, called Herkimer diamonds, present a dilemma for collectors. They are quite brittle, and found in very tough silicified dolostone. Crystals in matrix are more interesting and more valuable than crystals without matrix, so you generally don't really want to remove them. Trimming is best done with a diamond saw, or a pressure trimmer. If you really want to just pop the crystals off, a hammer and chisel will do that just fine.
