Diamonds are the most compact form of wealth in existence, and can be worth more than one hundred thousand times their weight in gold. Few, if any, other assets allow you to carry millions of dollars in your pocket without revealing a thing to others.

Security companies provide a critical service to the diamond industry by providing safe and secure transport of diamonds. Some companies cannot even conduct business without these security agents, as their insurance providers mandate their use. Anyone who has ever walked the diamond district of Antwerp would have noticed the dozens of security people walking the streets with unmarked suitcases of diamonds moving from place to place.
