Three stones discovered in KwaHlathi in South Africa's KwaZulu-Natal Province last week are not diamonds, but quartz crystal, whose value is significantly lower than diamonds, according to preliminary findings made by local authorities and cited by the Daily Mail.
Researchers also stated that the site rested near a sill of volcanic rock named dolerite which was not in a zone where diamond occurrences are usually present.
Prior to the report, several ambitious people had already started selling the stones, with the starting price ranging from 100 rand (approx. $7) to 300 rand (around $21).
The diamond industry is huge in South Africa as diamond mines there produce millions of carats annually, with the industry contributing billions to the local economy.
