5. KaDeWe, Berlin.
In the early morning hours of January 27, 2009 three masked men broke into Germany's luxury department store Kaufhaus Des Westens, also known as KaDeWe. The store's CCTV footage showed exactly how they climbed into the grand main hall, broke open cabinets and display cases and stripped the store of €5 million worth of jewelry and watches.
At first, the police thought that traces of DNA found on a glove left at the scene would make nabbing the o criminals responsible for one of the most spectacular jewelry heists in Germany's history, easy. Imagine their surprise when the DNA evidence led to identical twins – which have innately near-identical DNA – rendering the usually full-proof evidence useless. Is that the perfect crime or what?
4. Graff, London.
In the summer of 2009, two snazzily-dressed thieves walked into a London Bond Street jewelry store, waved handguns at the shop's workers and stepped out with $65 million worth of gems in one of Britain's biggest jewelry heists.
It was the third time a Graff store in London was targeted in a high-profile raid in the past six years. The two's loot included dozens of high-end rings, bracelets, necklaces and watches worth $65 million.
3. Antwerp Diamond Center.
In wintery weekend on February 2003, 123 safety deposit boxes tucked away in the Antwerp Diamond Center's main vault were completely emptied. Belgian authorities didn't discover the theft until Monday, realizing the robbers got away with an estimated $60 million worth of gems. While the ring behind what has been called the greatest jewelry heist in the world history, was eventually jailed, the whereabouts of the diamonds remains unknown.
2. Harry Winstron, Paris.
In December of 2008, four armed men – three of whom were dressed women’s clothing – marched into Harry Winstron's Paris, store shortly before closing time, and took the high-end store for $108 million worth of jewels.
Robbing the store wasn't enough for the foursome, who also robbed the storage room, causing Winston's stock to dip 9%. The same store was robbed just one year prior, when thieves netted €10 million worth of jewels. Which brings us to the obvious question: wouldn't hiring some armed guards be cheaper than getting robbed every year?
1. Schiphol Airport, Amsterdam.
February 25, 2005 saw $118 million worth of diamonds and gems stolen at Amsterdam's Schiphol Airport. Many of the stones were uncut, which made them much harder to value and trace. Unlike the other heists on the list, which probably involve some planning, the Schiphol robbery was executed in a “smash and grab” fashion.
It was later discovered that about two weeks prior to the robbery, four men stole a KLM cargo truck and uniforms in order to divert suspicion and allow them to move around the secure areas of the airport freely.
On the day of the robbery, the thieves drove right up to a KLM truck that was carrying a large haul of uncut diamonds, intended for delivery to Antwerp, and held up the drivers at gun-point,and in front of numerous witnesses, before simply getting in the truck and driving away. It was the second time in six months that the airport terminal was breached.
