A Rock and a Hard Place

There are basically two things you can do if you misplace a diamond worth $6 million. Jump off a building or take out an ad.

At Brinks, the world’s largest diamond and gold delivery firm, they chose the latter—pleading in newspapers worldwide last week for the return of what is being called an “unbelievably clear and extremely rare” 162.5-carat diamond that somehow went missing during a recent flight from Switzerland to South Africa.

Nicholas Trowbridge of Brinks in Switzerland said professional thieves are almost certainly to blame, though how they might have seized the stone remains a mystery.
