In the 1700s, Brazil was enjoying a gold rush and as the gold miners panned rivers, they also found a few diamonds. India’s diamonds were the only diamonds known in the world until the 1700s when diamonds were found in Brazil. Historians have found evidence of villagers in India finding diamonds in rivers and using them in trade as far back as 400 B.C. Remember that diamonds with a higher quality and value always enter the jewellery market, while diamonds with lesser value are used in industry. Interestingly, Namibia and Sierra Leone produce the least amount of diamonds every year, but the few that they produce have the highest value in the world. Now we are going list the same countries and rate them according to value of the diamonds that they produce. The list above rates the world’s largest diamond-producing countries by the volume that they produce every year.

Sierra Leone – 609 thousand carats of diamonds.

South Africa – 8 million carats of diamonds.

Zimbabwe – 10 million carats of diamonds.

Australia – 12 million carats of diamonds.

Botswana – 23 million carats of diamonds.

Here is a list of these countries and the approximate amount of diamonds that they produce every year: Which countries have diamond reserves?ĭiamonds have been found in more than 30 different countries located in both the Northern and Southern Hemispheres, but only 10 of these countries stand out for the volume of diamonds that they produce. Only a few natural occurrences, including the cataclysmic movement of earth’s tectonic plates and the impact of meteorites, can cause this type of pressure on the earth’s mantle and they happened many years ago.Īfter carbon has been made into diamonds, the precious stones remain hidden in rock until volcanic activity brings them nearer to the earth’s surface. Once they have bonded, carbon atoms need to undergo about 50 kilograms of pressure per square centimeter to make them into crystals with rigid, unbreakable bonds. It’s intense heat keeps the mantle at temperatures well above 1,000 o C and causes the carbon atoms to form chemical bonds with each other. The earth’s core beneath the mantle is made of molten metals. The mantle is composed of solid rock and is rich in magnesium, iron and carbon.

The only place carbon is transformed into diamonds is in the earth’s mantle which lies 160 kilometers beneath our feet. The majority of this carbon will never become diamonds, because it isn’t exposed to enough heat and pressure.

Scientists have found it in the atmosphere and the ocean, in every rock and handful of soil, as well as in our bodies. Diamonds play an important part in our personal lives and in the world around us, but where do all these diamonds come from? Diamonds are made from carbon, heat and pressureĬarbon is everywhere.
