Famously known as the “Heist of the Century,” the Antwerp diamond heist was one of the biggest thefts at this point in time. It took place between February 15th to 16th, 2013. The underground vault where the diamonds were stored was secured by 10 layers of security, including a lock with 100 million possible combinations, infrared heat detectors, a seismic sensor, doppler radar, and a magnetic field! And still, the thieves managed to steal diamonds, gold, and other jewelry worth more than USD $100 million.

The mastermind of the robbery, Leonardo Notarbartolo, was later arrested by police. He was found via DNA evidence gathered from a partially eaten sandwich found near the crime scene. He was sentenced to 10 years of imprisonment. However, the diamonds are yet to be recovered.

The Tucker Cross was the name given to the emerald-studded 22-carat gold cross discovered by the late diver Teddy Tucker in 1955. He found the cross amid the wreckage of a Spanish galleon known as the “San Pedro,” originally lost off the Bermuda coast in 1594.

Teddy Tucker sold the cross to the Government of Bermuda in 1959. It was initially kept at the Bermuda Aquarium Museum and Zoo, before being transferred to the Bermuda Maritime Museum.

In 1975, just before the visit of Queen Elizabeth, it was found that the cross had been stolen and replaced with a replica! Despite a long investigation by Bermuda Police, FBI, Scotland Yard and Interpol, the original Tucker cross has never been recovered.
