Best Answer

Alluvial diamonds are those found under water having been washed away from the volcanic pipe where they erupted from the earth's mantle by flowing water.

You can find alluvial diamonds in riverbeds or in the sea.

Where diamonds are found are called?

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.


Where are diamonds usually found on earth?

Usually, diamonds are found on earth around volcanic pipes -- the core of diamond mines, or downstream from volcanic pipes -- alluvial diamonds -- when flowing water rolls diamond stones away from the pipes where they erupted to the earth's surface.


How do diamonds end up in streambeds?

Diamonds are erupted to the surface of earth by volcanic pipes. When water flows over these pipes, diamonds are tumbled out and can be found in stream beds. They can also be found at the mouths of rivers that empty into the sea. These diamonds are called alluvial diamonds. These diamonds have been removed from the kimberlite material that erupted with them, and are eroded by the flowing water. Often, this process takes millions of years.


Can sand metal and diamonds be mined from placer deposits?

Apparently alluvial diamonds migrate into placer deposits, being moved there by natural means, such as flowing water. Other materials are simply ground into tiny bits and ultimately 'placed' into the low spots in the geography. Sand is a descriptor used to name the quality of the tiny stones that make up most of the materials in placer deposits: some metal bits and alluvial diamonds are also found in placer deposits. You can read more about them, below.


How do you pan for diamonds?

One does not typically 'pan' for diamonds, like one might pan for gold or silver. Panning assumes that a water source washes over the repository of (valuables) and then moves the material into an area where panning can be accomplished.In order to find a diamond under water, the source of water must run over a volcanic pipe containing diamonds. Some diamonds are found this way, and they are called alluvial diamonds.It is more common to mine in the earth for diamonds.

What is the biggest alluvial diamond ever found?

Diamonds have been part of human history for about 6,000 years, before humans began keeping written records of alluvial diamonds. Identifying the biggest alluvial diamond ever found, then, is not possible. Probably, the first diamond found and admired was an alluvial diamond. You can read more, below.


Where does the gathering of blood diamonds have the most significant impact on the people?

Anywhere diamonds can be dug from shallow locations or alluvial stones that can be 'panned' in running watter.


Where are the biggest diamonds found?

The biggest diamonds are found in the earth, in diamond mines or as alluvial stones deposited by water in rivers and as rivers empty into the ocean.

How do diamonds arrive in streams?

Some diamonds are found in rivers and in the mouths of rivers as they flow into the ocean. Water flowing over the tops of the volcanic pipes -- which push the stones to the earth's surface -- deposits the diamonds where they can be found in flowing water.These diamonds are called alluvial diamonds.


What are 2 types of diamond mines?

Diamonds are mined around the volcanic pipe that erupted them out of the earth's mantle. Generally, this means that diamond mines are circular and conical in their shape, the cone being inverted. Also, diamonds are found away from the pipes, having been moved by running water. These diamonds -- alluvial diamonds -- are found in beds where water flows or has flowed, from the pipe to the outlet of the water, sometimes in the sea. Alluvial diamonds mined at the mouths of rivers are scooped up with the seabed and sorted, then, from the surrounding materials like the diamonds in conical mines are sorted.


Can one tell if two diamonds came from the same mine?

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.


How are diamonds mined?

The diamonds are mined by digging the earth. Sometimes the very big open pits are left after the diamond exploration. Some diamonds are found on top of the earth, having been tumbled downstream from volcanic pipes by flowing water. These are known as alluvial diamonds, and are mined by hand -- workers sifting through the bottoms of riverbeds using sieves and water to separate the raw diamonds from other material. Alluvial diamonds may also be found in ocean water at the mouths of rivers.


What are diamond deposits called?

Diamonds are erupted to the earth's surface by way of volcanic pipes. Diamonds are mined from these pipes. When water flows over these pipes, diamonds can tumble into the stream bed, and some diamonds are carried to the mouths of rivers into salt water. These are called alluvial diamonds. The name of the diamond deposit, then, depends on where you find the diamanods. .

Can diamonds be found in oceans?

Yes.Called alluvial diamonds, these stones have been pushed into the sea by water flowing over volcanic pipes, which erupt to the earth's surface and bring diamonds with them.Generally, then, these stones found in salt water are located near the mouths of rivers.


Which country uses the most diamonds?

Africa has the largest producer in the worldAfrica is not a country - it is a continent. Zimbabwe (a country within the continent of Africa) has largest known concentration of diamonds in the world.Actually, I believe that Botswana is the largest producer of diamonds in the world. If Zimbabwe had as much in reserves of diamonds as Botswana, they would probably have their own currency.
