Mega Aggron Stone Please?!

To start off, not entirely sure if this is where this goes. Anyways, I have Pokemon X, beat it, got all the items, ect., but I cannot find anyone that I know that is willing to trade me over a mega Aggron stone. If someone has one please let me know. I have everything including the masterball and all the other mega stones ect. Lemme know if you'd be willing to part and what you might want for it and thats all good then! Even if you don't have the stone, if you wanted to post your friend code as well I'll add you as well to battle/trade/compete with some time. Happy hunting to everyone!
