4. Anne-Marie Graff- $2.1 Billion
Age: 75
Company: Graff Diamonds
Country: British
According to Forbes magazine, Anne-Marie Graff and her children are the owners of some stocks at their company Graff Diamonds, worth up to $3.1 billion.
Of course, as you might notice, she is the wife of British billionaire jeweler Laurence Graff, who is also ranked in our list at 5th place.
The couple have been married for over 47 years, but that until he went on and fathered a child with a former 34-year-old employee, which made Anne-Marie to file for divorce.
The divorce, which could have been Britain’s biggest divorce settlement, hasn’t happened as the couple appears to have reconciled.
