Via rising molten magma or by mining.
they get to the surface from volcanoes. when they erupt, they bring diamonds with them.
There are some tests that a certified gemologist can conduct that can generally pinpoint the location or source of a diamond. Whether or not the diamonds came from the same 'mine', may be problematic, since many diamonds are harvested using techniques other than mining. For example, if water runs over the volcanic pipe that pushed the diamonds to the earth's surface and diamonds are washed downhill, then harvested as alluvial diamonds, the mined volcanic pipe may be substantially distant from the alluvial diamond find. But the source is the same.
There are numerous 'kinds' of diamonds -- too many to list. The number of diamonds cannot be determined, since not all diamonds have been mined to date.
No, people say ROTATED SQUARES are diamonds - It's a common mistake. Diamonds are just rotated squares - NOT diamonds. Just remember that.
Diamonds are VALUABLE
Natural diamonds are as old as Mother Earth herself.
Diamonds are erupted to the surface of the earth by volcanic pipes.
Diamonds erupt to the surface of the earth at the top of the volcanic pipes that contain them.
Carbon.
No volcano produces diamonds. Diamonds are erupted to the surface of the earth through volcanic pipes, which look like upside-down volcanoes. These pipes erupt indicator minerals, some of which include diamonds.
Raw diamonds are found in the earth, where they are blasted to the surface by volcanic pipes.
Diamonds are erupted to the earth's surface by way of volcanic pipes.
Diamonds are formed deep within the earth's mantle, under enormous pressure and extreme, high heat. Then, volcanic pipes erupt the diamonds to the earth's surface.
Diamonds are erupted to the earth's surface through volcanic pipes. These pipes can be mined.
People in many African nations mine for diamonds around the volcanic pipes that erupted the diamonds to the earth's surface.
Diamonds are erupted to the earth's surface with indicator minerals, including kimberlite. Not all diamonds are 'stuck' to anything else.
The geology around the Grater of Diamonds was covered by the surface effects of a volcanic pipe which deposited diamonds and indicator minerals there.
All diamonds are erupted to the surface of the earth from deep within the mantle, where diamonds are formed. Diamonds are mined on every continent on earth except Europe and Antarctica.
