Alternately, he might want people to believe he has transfigured his father’s rock again, but not be actually planning to keep it transfigured, because he wants to carry the Hermione diamond and let people think it is the rock.
Any thoughts on the changing/cooling issue? That seems to really get brushed off. Is a perfect diamond supposed to be absolutely stable at room temperature?
Contrary to the popular belief that “diamonds are forever”, they are in fact thermodynamically unstable under normal
conditions and transform into graphite.[13] However, due to a high activation energy barrier, the transition into
graphite is so extremely slow at room temperature as to be unnoticeable.

It isn’t
What is the most stable thing at room temperature, with magical assistance?
Arguably a troll—it’s constantly transfiguring itself back into the same form.
I don’t think that a troll’s transfiguration is supposed be stable at that level of detail.
So transfigure Hermione’s brain into a troll until you figure out how to save her.
