South Africa's diamonds have a long history. At present, almost 85% of the best quality products in the diamond circulation industry are from South Africa. Even the early discovery of diamonds took place in South Africa. The story of diamonds dates back to 1870, when a farmer named Adrian van burl Vick owned a farm near Kimberley, North Cape Province. When he found his children playing with several diamonds, all the wonderful follow-up began.
Why there are so many diamonds in South Africa? In the geological history, there have been many volcanic activities in South Africa. The intense high temperature gathers the carbon materials in the earth's crust and crystallizes them into diamonds. Those high-quality diamonds reach the standard of making ornaments, and South Africa has gradually become the distribution center of high-grade diamonds.
So, how does such a precious treasure get to the ground? It turns out that diamonds are sent to the surface through volcanic eruption, and most of the volcanic eruption channels in South Africa are in a kind of similar 'throat' rock pipe called kimberlite, which flows from the earth's crust to the ground like a pipe. Because these pipes were formed by ancient volcanic movements, the miners had to dig down as much as they could to get the diamonds, until the hill became a hole.

Today, this scenic spot, simply called "big hole", has become a world famous place. The Kimberley hole covers an area of 17 hectares and a radius of 1.6 km. More than 22 million tons of earth have been dug from here, producing 14504566 carats of diamonds (2722 kg). It wasn't until 1914 that the stones were completely excavated. At that time, the open pit was 215 meters deep and the mining tunnel was 1100 meters deep.
Geologists have also found other kimberlite pipes containing diamonds in South Africa, and today there are many large holes around Kimberley and in other parts of South Africa. South Africa has become a real diamond producing country in the world.
