Ringmione seems to be the most popular hypothesis at the moment. It strikes me as extremely careless a plan for Harry to attempt; recall Quirrell's comments after the battle with the transfigured armor, and the first battle where passing out ended the transfiguration on the marshmallow he was practicing with.

However, I took "Harry's parents come to Hogwarts" as a completely insane move that Dumbledore/Macgonnagle would be highly unlikely to pull, and yet the elder wizards thought rather differently from me and did it anyway. I still think using the ring involves Harry assigning way too little cleverness to Dumbledore, but in light of the ordeal with his parents I'll give it a little more probability weight.

(Note also that Harry did something under the covers when Flitwick showed up.)

Harry will already lose a finger if anyone finite's his ring. He practiced with the marshmallow because the rapid expansion of the rock would tear off his finger.

Ringmione isn't much more of a personal risk to him.

This is a world where there are potions that can regrow bones in a single night. I think it wouldn't matter that much to Harry if he did lose his finger.

Cannon!harry does NOT like skele grow. I don't expect Rational!Harry would like it any more, even if he wouldn't complain about it to anyone.

No, but Hermione's life is on the line - he'd bite off his own fingers to save her.

No, the rock might crush his finger, or cause other problems, but it would push his hand out of the way, while with a ring, the center would close.

ch 30

He'd sustained that Transfiguration for seventeen days, and would now need to start over.

Could've been worse. He could've done this fourteen days later, after Professor McGonagall had approved him to Transfigure his father's rock. That was one very good lesson to learn the easy way.

Note to self: Always remove ring from finger before completely exhausting magic.

This implies to me that that his finger would've gotten wrecked if that was a rock. Remember, finite on the rock blew out both the front and back of the troll's head. It wasn't just expanding in a confined spot; it expanded fast enough to blow out both sides. Explosive de-transfiguration. Certainly enough to tear off a 10 year old's finger.
