The Godmodder separates the diamond block from Yorehammer and gives it to me to avoid being weakened by the Curse of Repetetiveness.
I make the diamond block immune to curses, and then curse the area around it with both the Curse of Repetetiveness (making unoriginal things useless) and the Curse of Creativity (making original things useless).
The SCP files say 682 is a three dimensional projection from a four dimensional universe, e.g. casting a shadow onto a 2d planar dimension. Armed with that knowledge I immerse 682 in an acid stronger than any other acid in the universe: antimatter. With the power of antimatter every single 3rd dimension atom of SCP-682 disappear into nonexistence, preventing him from being able to use his projected form in our dimension, allowing me to waltz in and grab the diamond.
I promptly set to work protecting the diamond in an impenetrable vault comprised of pure antimatter, and I send it 2.537 million light years away to the Andromeda Galaxy to be protected by Deadpool (who is arguably the most powerful being in the universe.) on a hidden, unnamed planet which you will probably not find ever due to the mathematically impossible to calculate number of star systems in that one galaxy.
