The Philosopher's Stone

The creation of this magical object was the primary goal of alchemy. There were two types: red, which could turn any metal into gold, and the white, which would turn any metal into silver. With a Philosopher's Stone an alchemist could see the heavens, make the Elixer of Life, which would grant its drinker perfect health and virtual immortality, attain great wealth, and could understand everything about animals, minerals, and vegetables.
