A 137-carat diamond hasn’t been seen in public since 1919. It had been hidden inside a Canadian bank for a century

The legendary 137-carat yellow gem known as the Florentine Diamond, long believed lost after the collapse of the Austro-Hungarian Empire, has resurfaced.

Now, three members of the former Habsburg imperial family say the fabled diamond was never stolen or lost, but safeguarded in secret for more than a century, according to the New York Times.
