Diamonds are one of the most precious gemstones in the world, and they have been prized for centuries for their beauty, rarity, and durability. But where do diamonds come from? How are they formed? And how do they get to the surface of the Earth?

In this blog post, we will explore the origins of diamonds, from their formation deep within the Earth’s mantle to their eventual discovery and extraction. We will also discuss the different types of diamonds and how they are graded for quality.

How Are Diamonds Formed?

Diamonds are formed under extreme conditions deep within the Earth’s mantle, at depths of 150 to 250 kilometers. The temperature at these depths can reach 1,500 degrees Celsius, and the pressure can be up to 50,000 times greater than at sea level.

In these extreme conditions, carbon atoms are forced to bond in a particular way, forming an incredibly strong and durable crystal structure. This crystal structure is what gives diamonds their characteristic hardness and brilliance.

The carbon atoms that form diamonds are thought to come from the Earth’s mantle, where they are released from the breakdown of other minerals. The carbon atoms then rise through the Earth’s crust, carried by a kimberlite rock.

Kimberlite is a rare type of rock, only found in a few places worldwide. South Africa, Botswana, and Russia are the world’s most famous diamond mines.

Different Types Of Diamonds

There are many different types of diamonds, each with its unique properties. Some of the most common types of diamonds include:

• Gem-quality diamonds: These are the most valuable type of diamond, and they are used in jewelry. Gem-quality diamonds are typically colorless or near-colorless and have a high level of clarity.
• Industrial diamonds are used in various industrial applications, such as cutting, drilling, and polishing. Industrial diamonds are typically less valuable than gem-quality diamonds but are still very hard and durable.
• Lab-grown diamonds: Lab-grown diamonds are created in a laboratory under controlled conditions. They have the same chemical and physical properties as natural diamonds but are much less expensive.

Diamond Sources Around The World

Here are some of the top diamond sources around the world:

•  South Africa: It is the leading producer of diamonds. The country has been mining diamonds for over 150 years, and it is home to some of the richest diamond deposits in the world.
• Botswana: it is the second-largest producer of diamonds in the world. The country has been mining diamonds since the 1970s, and it is home to some of the world’s most valuable diamond mines.
• Russia: Russia is the third-largest producer of diamonds in the world. The country has been mining diamonds since the 1950s, and it is home to some of the world’s most remote and inaccessible diamond mines.
• Canada: Canada is the fourth-largest producer of diamonds in the world. The country has been mining diamonds since the 1990s, and it is home to some of the world’s most technologically advanced diamond mines.
• Angola: Angola is the fifth-largest producer of diamonds in the world. The country has been mining diamonds since the 1980s, and it is home to some of the world’s most conflict-ridden diamond mines.

The diamond industry is constantly evolving, and the sources of diamonds are changing as well. A growing interest has recently been in mining diamonds on the ocean floor. There are believed to be large deposits of diamonds on the ocean floor, and some companies are already beginning to explore the possibility of mining them.

Another area of interest for the diamond industry is the development of lab-grown diamonds. Lab-grown diamonds are formulated in the laboratory under controlled conditions and have the same chemical and physical properties as natural diamonds. Lab-grown diamonds are much less expensive than natural diamonds and are becoming increasingly popular with consumers.

The diamond industry will likely continue to evolve in the coming years, and the sources of diamonds will continue to change. However, one certain thing is that diamonds will remain a valuable commodity for many years to come.
