Zimbabwean diamonds in Brazil

Zimbabwean diamonds were in the news recently, with reports of their alluvial deposits – the base of their boom production in the last years – being close to exhaustion. These ones were photographed in Diamantina, Minas Gerais (Brazil), far from home.

They are not the prettiest thing, certainly not like the famed Angolan alluvial diamonds or for that matter the local Jequitinhonha river diamonds. There surely is an interesting story behind their voyage, though.

How have they got there? Where may have they gone since?
