Those who are looking for an answer to the question «How and where do diamonds form?» often ask the following questions:

👉 Where do diamonds form?

They form beneath the continental crust, from pure carbon. This carbon may either come from exclusively non-organic sources, organic sources, or a blend of the two. Diamonds formed from inorganic carbon are called harzburgitic diamonds, while those formed from some amount of organic carbon are called eclogitic diamonds.

👉 Diamonds form under pressure?

Diamonds are only made up of one element: carbon. When carbon dioxide is buried 100 miles under the Earth's surface and heated to a temperature of 2,200 degrees Fahrenheit, and then squeezed to a pressure of 725,000 lb per square inch, a diamond is formed.

HOW DIAMONDS ARE FORMED. Diamonds were formed over 3 billion years ago deep within the Earth’s crust under conditions of intense heat and pressure that cause carbon atoms to crystallise forming diamonds. Diamonds are found at a depth of approx. 150-200km below the surface of the Earth.

Diamonds are not only formed under the heat and pressure of the Earth’s gravity, but can form in the midst of a collision between Earth and an asteroid. Russia claims to have a deposit of diamonds resulting from a collision 35 Million years ago. Diamonds created during a cosmic collision are not likely to be of gemstone quality.

1) Diamond Formation in Earth's Mantle. Geologists believe that the diamonds in all of Earth's commercial diamond deposits were formed in the mantle and delivered to the surface by deep-source volcanic eruptions. These eruptions produce the kimberlite and lamproite pipes that are sought after by diamond prospectors.

Diamonds Form from Fluids in the Mantle That Migrate Due to Plate Tectonics Diamond is a metasomatic mineral that forms during migration of carbon-bearing fluids, which means that it forms from fluids and melts that move through the mantle.

What Countries Do Diamonds Come From? Globally, diamonds can be found in more than 30 countries around the world. However, the vast majority of diamond production is concentrated within 5 countries, namely: Russia (45 million carats), Botswana (24 million carats), Canada (19 million carats), Democratic Republic of Congo (14 million carats) and Australia (13 million carats).

Diamonds are continually forming and growing there, just as they have been for billions of years. The gems are brought to the surface of the Earth during a seismic event like a volcanic eruption, embedded in large chunks of rocks called xenoliths. 2. Diamond formation in subduction zones.
