South Africa gems that sparked rush are quartz not diamonds

PO1 Tony Holland always informative and meaningful, thanks for the read and share my friend.

PO1 Tony Holland "The South African government says that stones found in a village last month are not diamonds but quartz.

A cattle herder first uncovered the stones in KwaZulu-Natal province. It prompted thousands to rush to KwaHlathi village, more than 300km (186 miles) south-east of Johannesburg.

But 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."
