Why We Love This Gemstone
Peridot crystals are found in meteorites: some rare extraterrestrial crystals are even big enough to facet as cut gemstones.
Most gems are colored by impurities such as iron. Peridot’s color is intrinsically yellow-green. Higher-quality stones have an intense color.
Peridot has extremely high double refraction: when you look closely through the gem, you can see two of each pavilion facet.
