The pocket emerald story that comes before that "we were very wealthy" line is even more telling. It's missing from that Independent article, but that article's based on this Business Insider interview: https://www.businessinsider.com/elon-musks-dad-tells-bi-abou...

> Elon, by his father’s recollection then probably 16 years old, and his brother Kimbal, decided to sell emeralds to Tiffany & Co. on Fifth Avenue in New York – one of the world's most famous jewelers – as his father lay sleeping. "They just walked into Tiffany’s and said, ‘Do you want to buy some emeralds?’" Errol recalled in an interview with Business Insider South Africa. "And they sold two emeralds, one was for $800 and I think the other one was for $1,200."

> A few days later the family returned to the store to find that Tiffany was selling the $800 emerald, now set in a ring, for $24,000 -- a markup of 30 times the price Elon had received for the gem.

> Errol has used the story as on object lesson in how retail works ever since. He was surprised but not concerned by the incident, Errol says, because money was plentiful.

> “We were very wealthy,” says Errol. “We had so much money at times we couldn't even close our safe.”
