Does anyone know what çactus this is?

Usually it's a Gymnocalycium mihanovichii grafted on a Hylocereus trigonus rootstock.

Thanks! I read on the internet that I should keep it in partial shade. But I've been keeping it in full sun since I've had it. I'ts been doing fine and has 6 big buds about to flower. So now I'm in doubt, should I let it standing in full sun since it's been doing fine there or should I move it because the internet said so? Could it be harmful over time to keep it in full sun?

It is a chlorophyll free mutant (that's the reason for grafting). I have had mine in full sun for five years and it is still alive but has not flowered as nicely as yours has. Quite tough overall.

It looks like this one hasn't been irradiated - Dark purple-green G. mihanovichii and friedrichii are quite common, if not the norm, and often sold on their own roots.
