The South African government clarified that the stones discovered in a village were not diamonds but quartz.
A cattle herder first uncovered the stones in KwaZulu-Natal province. It prompted thousands to rush to KwaHlathi village, some 300km southeast of Johannesburg.
After conducting tests, officials have said the stones are quartz crystals, which are far less valuable.
After feldspar, quartz is the most abundant mineral in the Earth’s crust.
“The tests conducted conclusively revealed that the stones discovered in the area are not diamonds,” a local government statement reportedly said.
Studies carried out in the area have revealed that the site where the stones were found is geographically located on the edge of the Karoo dolerite sill, which is not in a zone where diamonds are normally found.
The council for Geoscience will be carrying out further studies to find out if there are any other minerals that may create jobs and improve the lives of tens of thousands of people who live in the area.
The government has asked people to stop digging because illegal mining practices have a negative impact on the environment.
