Where does Australia rank in the world's top ten diamond producing regions?

 When it comes to diamonds, many people will think of South African diamonds first. South Africa is the world's number one diamond producing country in many people's minds. However, in fact, whether in terms of output value or output, South Africa is no longer the world's number one as you think. According to surveys, diamonds are produced all over the world. More than 30 countries have diamond resources, with an annual output of about 100 million carats. Today we will take a look at the top ten diamond producing countries in the world.

1. Australia is one of the top ten diamond producing areas in the world

Rio Tinto's Argyle diamond mine in the kimberlite belt in eastern Western Australia is the world's most productive diamond mine and the world's main source of pink and red diamonds, accounting for 90% of the world's annual production of red and pink diamonds. The Argyle mine also produces champagne, brandy and blue diamonds.

2. Botswana is one of the world's top ten diamond producing areas

Botswana is rich in high-quality diamonds, 50% of which are gem-grade diamonds , and its output value ranks first in the world. Botswana's diamonds come from open-pit kimberlite. The huge mines include the Orapa Pipe (1967), the Letihakena Pipe (1977) and the Jwaneng Diamond Mine (1982). According to the world's diamond production distribution map, the total output of the three mines exceeded 15 million carats in 1989.

3. Russia is one of the top ten diamond producing countries in the world

Russian diamonds are mainly distributed in the Yakutia region in central Siberia. On the world's diamond production distribution map, more than 100 diamond-bearing kimberlite pipes were found. In 1988, Russia found a new diamond mine near Europe. Russia's diamond production is about 12 million carats, half of which are gem-grade. Over the years, Russia has formed an independent diamond mining, processing and sales system. Its diamonds are large in quantity, high in quality and good in uniformity, and are very competitive in the market.

4. South Africa is one of the top ten diamond producing areas in the world

Kimberley diamond mine, from 1866 to 1914, 50,000 miners used shovels and other tools to dig, and a total of 2,722 kilograms of diamonds were dug. Currently, the South African government is trying to apply for the Kimberley mine to be a world cultural heritage site.

South Africa's diamonds are famous for their large size and high quality. 50% of the rough diamonds mined from the mines can reach gem quality. Fifty years ago, South Africa's diamond production ranked first in the world. As time goes by, South Africa's diamond production has decreased year by year. In 1987, South Africa's diamond production was 10 million carats, accounting for about 10% of the world's total production.

5. Zaire is one of the world's top ten diamond producing areas

Zaire is now the Democratic Republic of Congo. Zaire is rich in natural resources and is known as the "world's raw material warehouse", "Central Africa's gem" and "geological miracle". The country is rich in a variety of non-ferrous metals, rare metals and non-metallic minerals, including copper, cobalt, zinc, manganese, tin, tantalum, germanium, tungsten, cadmium, nickel, chromium and other metals and industrial diamonds.

6. Canada is one of the top ten diamond producing countries in the world

A few years ago, it was reported that a large amount of kimberlite was discovered in northern Canada, and diamond production could account for 10% of the world's production in a few years. On July 16, 1871, the Coulisberg Partnership Mining Team, which insisted on digging deep, succeeded. They kept digging deep on the dozens of square meters of land they occupied, and on this day they finally found the diamonds they had dreamed of. On the world's diamond production distribution map, the world's first diamond mine was born. It was named "Coulisberg Mine" and also called "New Boom Mine".

7. Namibia is one of the world's top ten diamond producing areas

In terms of the proportion of rough diamonds and gem-quality diamonds, the best diamonds come from diamonds mined from alluvial deposits in Namibia. These diamonds undergo natural weathering and are transported to the seashore, a journey of up to 1,000 miles. After this journey, the fragile parts of the diamonds are separated. In a specific sedimentary environment, diamonds are distributed in the rock strata in a certain pattern according to different particle sizes and shapes.

8. India is one of the top ten diamond producing countries in the world

In the world's diamond production distribution map, India is the first country in the world to discover diamonds . 3,000 years ago, India was the only place where diamonds were produced. From 2,500 years ago to the early 18th century, the Krishna River, the Penna River and its tributaries in India were the only places in the world where diamonds were produced. Many famous diamonds in history, such as the Kohi-Noor, the Orloff and the Great Mogul, all came from India. Due to excessive mining, India's diamond production has become so small that it can be ignored today.

9. Brazil is one of the top ten diamond producing countries in the world

The discovery and mining of diamonds in Brazil in 1725 made Brazil replace India as the most important diamond producing area in the world at that time.

10. China is one of the world's top ten diamond producing areas

China ranks 10th in the world in terms of proven diamond reserves and production , with an annual output of 200,000 carats. The main diamond production areas in the world are Wafangdian, Liaoning, Mengyin, Shandong, and the Yuanjiang River Basin, Hunan. Wafangdian, Liaoning is currently the largest diamond mine in Asia. Diamond placers are found in the Yuanjiang River Basin, Hunan, Tibet, Guangxi, and the Tanlu Fault, which spans Jiangsu and Anhui provinces.
