Or Harry transfigured Hermione’s body into a rock and then the rock into a brown diamond. Unless the story explicitly disallows double transfigurations and I missed it.
I thought this, but the spell used to undo a transformation by Harry in 89 is ‘Finite Incantatem’ which sounds more like ‘stop magic happening here’ rather than ‘undo a single transformation’, especially considering its varied other uses. Assuming Dumbledore didn’t make a basic error (he didn’t) I feel as though my stone hypothesis from earlier has been falsified.
My problem with that is that the rock should then still be a ‘transfigured object’ for the purposes of the spells and detected when Dumbledore examines the untransfigured diamond.
