Diamond Scam Probe Reopens Scandal Italian Banks Want to Forget

(Bloomberg) - In 2014, Massimo Balestra received a call from an employee at his bank, offering a risk-free investment “as secure as a wall safe.” The resident of a small northern Italian town ended up spending 6,945 euros ($7,876) on a diamond that he says he hasn’t seen since. Balestra is one of almost 100,000 Italians who bought so called “investment diamonds” at the urging of their banks in a widespread arrangement that’s now the target of a criminal investigation by the country’s financial police, according to people with knowledge of the matter. Investigators allege that Italy’s biggest banks hooked up their clients with diamond brokers who sold them stones for as much as double their market price.
