@kimlockhartga There's been much more revealed about it since.
There was definitely no mine anywhere in the area Errol claims. The gems came from Copperbelt mines (quite possibly stolen) and he either smuggled them out himself or had them illegally delivered to Johannesburg, where he had a gem dealership, where the stones were cut and polished.
He was allowed to deal in gems - that's not the issue. The problem was all the taxes and duties on these imports he wasn't paying.
It gets even more fun. He laundered those profits through an "Israeli broker" and sent both the money and suitcases of gems to dear Elon, the other kids, and ex-wife Maye in Canada and the US.
The stories about how Maye and Errol had this horribly acrimonious divorce are also bollocks. I'm prepared to believe he was abusive - the whole lot of them are nasty arseholes - but Maye playing destitute victim is a load of cobblers.
She used to pick up the kids from school in her latest-model blue German luxury sedan (when Errol wasn't greeting them in the Rolls).
