Question about diamond locations.

[Kentucky Kache]

Does anyone know what kinds of locations diamonds are found?
Are they usually in open areas, or mines? If mines, are the mines usually vertical or horizontal? Are they found in creeks, rivers and streams? Thanks for any info.

From what I understand, they are found in
(extinct volcanos), the vertical pipes .
Of course if they have been subjected to erosion such as wind, or water, they could be found in creekbeds or such.

We find occasional diamonds in our sluices in southern Oregon. Mostly industrial grade but others have been cut that are nice.
The whole area is very volcanic.

Here in Wyoming I look for areas of dark green grass in the spring. The areas will be round, no larger than 40 yards I have found and free of any wood. like sage brush or trees. I have heard that some mountain lakes that are circular and "parks" could be diamond bearing areas do to the Kimberlite soil. Kimberlight erodes faster than the soil around it making impressions in the land scape Wooded plant species will not grow in Kimberlite soil, but grass will thrive in it and turn dark green in spring. hope this helps a little.

Thank you, that does help.

In the Midwest the glacial deposits contain diamonds. Other areas of the country (including CA) have produced diamonds while panning for gold. It's almost laughable that so many '49ers couldn't find much gold, but they were throwing diamonds over their shoulders getting to the next pan.

Great post Pcarrol,

Definitely volcanic kimberlite pipes are what transport diamonds and other gemstones to the Earths surface. The most famous one in the US is located in Arkansas, now called Crater of Diamonds State Park.

The other volcanic pipes that transport Diamonds to the surface are Lamprolite pipes, although all kimberlite/lamprolite pipes do not contain diamonds.

Here in Indiana Diamonds have been found in the creeks and streams due to glacial deposits. I have not heard of any found in Kentucky though maybe some do exist there.

There is a famous story of a large diamond being found near where I live. from accounts I've heard, I think the story is true.
