Sunstone
Sunstone looks like it has many little suns inside it, which is why the ancient Greeks named it so. The name comes from the Greek word “Helios,” meaning Sun.
With over 15 varieties in red, orange, yellow, green, black, and colorless hues, not all Sunstones show optical illusions. The visual effects come from the mineral inclusions of Pyrite, Goethite, Copper, or Hematite in the Sunstone crystal.
