Harry Potter adventures in time
The Sword of Gryffindor was a goblin-made sword that was owned by the famed wizard Godric Gryffindor, one of the four founders of Hogwarts School of Witchcraft and Wizardry. It was a masterpiece made by the goblins, with a silver blade and a handle with egg-sized rubies gleaming upon it. The name Godric Gryffindor was engraved just below the hilt.
The Sword and the Sorting Hat (both belonged to Gryffindor) are the only known relics of the four founders of Hogwarts not turned into a Horcrux. It is one of the few things that can destroy a Horcrux and Harry and his friends use it later.

The goblins claimed that Gryffindor had stolen the sword from the Goblins, believing that all goblin-made objects belong to the maker and should be returned after the original purchaser died. They therefore consider the sword to have been "stolen.
