scandiobabingtonite is biaxial positive, which means it will refract light along two axes. it exhibits a 2v=64(2)°, strong dispersion with r>v, and displays strong pleochroism with colors ranging from pink (γ') to green(α'). the extinction angle along the (110) is 6°. z:φ=-250°, ρ=47°; y:φ=146°, ρ=75°; x:φ=42°, ρ=47°.
