Walter Earl Morrison was apparently unloading a plane at Sky Harbor Airport in Arizona, when he noticed the precious stone

Morrison is alleged to have then swiped the shiny, ridiculously expensive stone and traded it for a mere 20 dollars worth of marijuana. 

A criminal mastermind, Walter is not. Although, the "expert" is edited to look like a bit of a moron in the above piece too.

He was promptly fired from his job by UPS and is being charged with felony theft by local police.
