I am curious too, but usually jewelry store robberies are done by robbers who already have a customer for it. Unless they are robbing for themselves which would be the most idiotic plan ever. So the particular person this group is doing this for will do what he does best with it in order to cover the trail, most likely they will melt it down, ship it overseas and sell it to someone who can create fake certificates for each jewel he will in turn make out of the melt.
