Very doubtful belonging of the ring to Hitler.
Firstly, the ring is very massive, the one who made it seemed to think that the place where they sit, and not their head: how such a high ring can be worn is not practical at all.
Secondly, I see the ring is peeling off, it is not gold, but simply covered with gold, from which I conclude that it is cheap.
It is unlikely that such nonsense could be presented to Hitler, while even gift rings lower to the ranks of the Reich were made of gold.
In general, I was not at all convinced by the photo - this is a collage for non-observant people who like to amuse themselves with fantasies
