Its density ranges from 3.27 to 3.37 g/cm³, and its refractive index is between 1.654 and 1.689.

Peridot has been valued since ancient times; the ancient Egyptians referred to it as the "stone of the sun," believing it could dispel darkness and evil. It was used as an amulet and is the birthstone for certain cultures. Over time, peridot has been imbued with various mystical meanings across different cultures, symbolizing love and harmony.
