Regarding the origin of diamonds, I believe that even if you have not bought diamonds and you don’t know them well, you will hear about “South African diamondsâ€. However, in fact, more than 30 countries around the world have diamond resources with an annual output of 100 million carats. about. The top five countries in production are Australia, Zaire, Botswana, Russia, and South Africa. Diamond production in these five countries accounts for around 90% of the world's diamond production. No country in South Africa may be as perfect as South Africa, combining originality and modernity. After the reinforced concrete is prosperous, it is the empty and lonely wilderness. This country, located at the southernmost tip of the African continent, has almost all mineral deposits except for oil. Although South Africa's diamond production ranks only fifth in the world, the quality of diamonds is very good. The crystals are mostly octahedron or dodecahedron, and about 25% of them can be used as gems for jewelry processing. Many famous diamonds such as “Cullian†are produced here, making South Africa the most important country for drilling. The mining of today's diamonds is still using the most primitive method. The semi-naked blacks are sweating and holding the tools to find the most expensive stone in the world.
