Top best answers to the question «Where do real diamonds come from»

Diamonds were first discovered and mined in India over 2,400 years ago. Over time, diamonds were found in many other areas around the world, including many in Africa. In today's trade, Africa, Russia, Australia, and Canada produce the most diamonds.

Diamonds are found near the Earth's surface, primarily in South Africa, Russia, Australia, Botswana, India, Brazil, China and USA. However, there are about 35 different countries in total that produce them. These valuable minerals are transported to the Earth's surface through erupting volcanoes.

A natural diamond's creation began around 100 miles below the Earth's surface. Each natural diamond is made of pure carbon, compressed by Earth's pressure over time, and is the hardest substance on earth that exists naturally.

Where do diamonds come from? Diamonds come from the Earth. A natural diamond’s creation began around 100 miles below the Earth’s surface. Each natural diamond is made of pure carbon, compressed by Earth’s pressure over time, and is the hardest substance on earth that exists naturally.

The diamonds are mined from the mines and prepared to head onto the next stage in the diamond finishing process. Countries in Africa producing the most diamonds are Botswana, Democratic Republic of Congo, Angola, and South Africa.

Approximately 3.3 billion years ago, and before dinosaurs walked the earth, diamonds were formed 150km – 200km deep below the earth’s crust in the melted rock of the mantle. The process started with Carbon molecules being compressed under high pressure of 45 to 60 kilo bar while undergoing intense heat of 900 degrees to 1300 degrees.

Diamonds are formed from carbon under intense heat and pressure. Diamonds form at depths of around 90 miles (150km), over millions and millions of years. The temperature at which they form is in the range of 2,000° Fahrenheit (1,100° Celsius) — too much hotter than this and the conditions are no longer suitable for their formation.

Most diamonds come from Russia, the Democratic Republic of the Congo, Australia, Canada, or Botswana.

Most diamonds come from the Earth's mantle, and most of this section discusses those diamonds. However, there are other sources. Some blocks of the crust, or terranes , have been buried deep enough as the crust thickened so they experienced ultra-high-pressure metamorphism .

Photo by Evan M. Smith. Boron is an element that is strongly concentrated at Earth’s surface. But in the mantle, where diamonds grow, the concentration of boron is extremely low. The boron content of type IIb diamonds is therefore unexpected and challenging to explain.

The majority of blue diamonds come from Rio Tinto’s Argyle Mine in Australia and Petra Diamonds’ Cullinan mine near Pretoria, South Africa. A smaller number of blue diamonds have been mined in the Goloconda mine in India. 29.6 carat Rough Blue Diamond by Petra Image via Petra Diamonds

Carefully drop the loose stone into the glass. If the gemstone sinks, it’s a real diamond. If it floats underneath or at the surface of the water, you have a fake on your hands. A real diamond has high density, so the water test shows if your stone matches this level of density.
