In the AD&D Forgotten Realms world, this is a powerful artifact created by Finder, who was a Human Mage and Bard. The artifact was created by joining a powerful magical object the original stone with a para-elemental ice. The process ended up killing one assistant and maiming another; for this crimes he was banished from Faerûn and his identity was wiped from the world. Finder later returns and ends up killing Moander and becoming a minor deity.
