FORSTERITE IS A SOLID SOLUTION OF OLIVINE THAT IS MAGNESIUM-RICH. THE OPPOSITE OF FORSTERITE IS FAYALITE, WHICH IS IRON-RICH. IT IS FOUND IN IGNEOUS AND METAMORPHIC ROCKS, AND HAS BEEN FOUND IN METEORITES. TWO POLYMORPHS OF FORSTERITE EXIST: WADSLEYITE AND RINGWOODITE.  
  
STANDARD FORSTERITE IS COLORLESS, BUT THERE IS A VARIANT OF FORSTERITE OLIVINE THAT IS YELLOWISH-GREEN, AND THAT IS THE GEMSTONE PERIDOT.  
  
IT HAS A MOHS HARDNESS OF 7.
