oh the question regarding his gems-
their location means nothing since his forcefield protects his body, which is in of itself totally impervious to superman/flash period. juggernaut can be balancing the gems on his nose like a dog treat and sim's guys still can't touch them.
i guess he puts the gems inside his clothing in some manner like most men do, after all he has to fight with his hands and at the same time keep the gems hidden it could be located anywhere on his person.
and AGAIN supes/flash can't touch them.
