Pipes of the minerals kimberlite and lamproite are often present in the Earth's upper mantle, and they carry diamond crystals in their pipe "trails." These minerals are resistant to weathering and are denser than quartz sand.

Where is a diamond most commonly found?

Diamonds are found in over 30 countries, but the leading producers of diamonds are:

• Russia.
• Botswana.
• Canada.
• Angola.
• South Africa.
• Democratic Republic of Congo.
• Namibia.

What kind of rock are diamonds found in?

Diamond is only formed at high pressures. It is found in kimberlite, an ultrabasic volcanic rock formed very deep in the Earth's crust. The extreme pressures needed to form diamonds are only reached at depths greater than 150km.

Can I find diamonds in my backyard?

You can find diamonds in your backyard, especially if you live in certain areas of the United States where ancient volcanic activity occurred. It's also possible to find diamonds in stream beds on your property.

How can you tell if a rock is a diamond?

The only hardness test that will identify a diamond is scratching corundum. Corundum, which includes all rubys and sapphires, is 9 on the hardiness scale. If your suspected diamond crystal can scratch corundum, then there is a good chance that you found a diamond. But NO OTHER HARDNESS TEST will identify a diamond.

Where can you find diamonds in the ground?

The following countries produce industrial grade diamonds: Australia, Botswana, Brazil, China, Congo, Russia and South Africa. Geologically speaking, natural diamonds are found in two environments. Most are found in kimberlites, which are pipe-like formations created as a result of volcanic and tectonic activity.

Can you find diamonds in sand?

Diamond occurs as a detrital mineral but its concentration in sand is always very low. However, diamond-bearing kimberlite pipes are often found by working through many fluvial sand samples but it is not diamond that prospectors are looking for.

How Deep Can diamonds be found?

Natural diamonds typically form 150–200 km below the surface of the earth. Diamond formation does not occur everywhere at these depths, but only below the oldest continents that have been stable for billions of years; these areas are known as cratons (see figure 2 in Summer 2018 Diamonds from the Deep).

Can you find diamonds on the beach?

The west coast of Namibia (South-West Africa) and South Africa is the only place in the world where diamonds have been deposited along the beach and coastal area. Tens of millions of tons of sand and diamond-bearing gravel are sorted through to find these gems.

What if I found a diamond?

Are diamonds found in sedimentary rocks?

Because of their supreme hardness and density, many diamonds survive the sedimentary processes and are frequently found in alluvial deposits. Minerals found in sedimentary rocks: Beryl.

Are raw diamonds worth anything?

With few common inclusions, raw diamonds are more valuable than diamonds with several common flaws. A raw diamond which has a brownish or yellowish tint is stronger but less valuable. On the other side, diamond with less hue is far more valuable. Transparent and colorless diamonds are too rare to find.

How does a raw diamond look?

Raw diamonds look like transparent stones with yellowish or brownish tints. There are some that are colorless but these are rare.

Is there a detector to find diamonds?

This leads to an important point: metal detectors will not detect non metal items such as gemstones, diamonds and pearls. What a metal detector can do is lead you to indicator minerals, which are used by prospectors. Prospectors follow the indicator trail back to gold or the volcanic pipe which may contain diamonds.

How do you find a diamond that fell off a ring?

If you're looking for a diamond that you have lost, treat its sparkle as your friend. Get the brightest, most reliable flashlight you have and scan it all over a room where you think you've lost your diamond. If you think you lost it outdoors, wait for nighttime to come.
