Diamond mining is the process of extracting diamonds from the earth. This can be done through various methods, including open-pit mining, where large holes are dug in the ground, and underground mining, which involves creating tunnels to reach deeper deposits. The extracted ore is then processed to separate the diamonds from other materials. Once the diamonds are extracted, they undergo sorting and grading based on size, quality, and color. Diamond mining operations can be found in several countries, including South Africa, Russia, and Australia. The industry is regulated to ensure ethical practices and minimize environmental impact.
