Garnet Group.
Almandine-Pyrope Series, Knorringite-Pyrope Series, Pyrope-Grossular Series.
Occurs predominantly in ultrabasic igneous rocks.
Pure end-member pyrope is colorless! (but rare).
Optical anisotropy may be present, caused by strain-induced birefringence, in relation to occurrence of more than a single (cubic) phase (Antao, 2021).

Physical Properties of Pyrope
Vitreous
Transparency:
Transparent, Translucent
Colour:
Blood red, orange red, purple red, pink, black red, colorless.
Comment:
The “alexandrite effect” is when its colour changes from green in the presence of daylight to purplish red under incandescent light. The UV-Vis spectra show two zones of transmittance, in the red region at 650–700 nm and the blue-green region at 460–510 nm. The absorption bands of Cr3+ and V3+ at 574 nm in the UV-Vis spectra are the main cause of the change in colour.
