Imagine finding a diamond in your roof? Unexplained diamonds have turned up in odd places, but the tech has come a long way since our heist and scientists can now figure out where they come from. Diamonds are the ultimate stealth wealth but tracing is making it tougher for thieves. Our Argyle diamonds went on a wild ride but in the end, some were recovered. Why have they reappeared all these years later and where is the rest of the multi-million dollar haul?

How do you pull off the perfect heist? Would you believe there's actually a recipe for it? While some heists are of Mission Impossible proportions, our caper is a little more domestic. Less motion sensors, infrared beams and seismic instruments; more shampoo bottles, kitchen sieves and lipstick. But what it lacked in high tech it made up for in sheer daring.

In all my years of journalism, there is one story that's stuck with me. Twenty years ago I was out bush chatting to diamond explorers about a heist that happened in the remote Kimberley region of Western Australia.
