Principal Exceptions to Gamp's Law of Elemental Transfiguration

The Principal Exceptions to Gamp's Law of Elemental Transfiguration are five magical objects that are an exception to Gamp's Law of Elemental Transfiguration — objects that cannot be created by magic. Out of the five exceptions, only four are mentioned in the Harry Potter series: food, love, life, and information. The fifth and final exception is likely money, as Rowling once remarked in an interview money is something wizards cannot simply materialise out of thin air, for the economic system of the Wizarding World would then be gravely flawed and disrupted. However, the Philosopher's Stone does possess the ability to make any metal into gold, which is the same metal as the currency of the Wizarding World. Love, the second of the five exceptions, is first mentioned in Harry Potter and the Half-Blood Prince by Horace Slughorn. Food, the first of the five exceptions, is first mentioned in Harry Potter and the Deathly Hallows, by Hermione Granger and is later mentioned again by Ron Weasley; the food in the kitchens at Hogwarts is not conjured; rather, it is transported upwards through the floor from the basement. In other instances in the series it appears that food has also been magically created; this explanation is likely valid here as well.
