It’s gorgeous in a silver … All minerals that are orthorhombic, like peridot, are biaxial and are defined by three principal axes: α, β, γ. Refractive index readings of faceted gems contain indices α = 1.653, β = 1.670, and γ = 1.689 with a corresponding biaxial birefringence of 0.036. The refractive index, as well as the specific gravity, slightly vary depending on the iron concentration; a dominant cause of peridot color variation. The numerical β index tends to shift towards the α and γ index with a correspond…
