History and Lore
Peridot's history is intertwined with ancient civilizations and celestial phenomena. The gemstone has been found in meteorites and volcanic lava, indicating its formation under extreme conditions.

In medieval Europe, peridot was associated with the healing properties of blood and was used in remedies for various ailments.
Geological Formation and Sources
Peridot is a gem variety of the mineral olivine, which is composed primarily of magnesium and iron. It is formed under high pressure and temperature conditions, typically in the Earth's mantle.
