Philosopher's Stone

The Philosopher's Stone is a fictional mystical item featured in comic books published by DC Comics. Yeah, it also appears in the Harry Potter stuff too, but the Americans refer to this item as a "Sorcerer's Stone", which admittedly, is slightly easier to pronounce. The DC version of the Philosopher's stone is associated with the Flash line of comic titles and first appeared in Showcase #14 in June, 1958. The Philosopher's Stone is a rock with mystical properties and can transmutate matter. In the modern era, it is wielded as a weapon by the super-villain known as Doctor Alchemy.
