rose quartz

LITMost massive rose quartz gets its colour from microscopic fibrous inclusions identified as a dumortierite-related mineral. The pink comes from the inclusions, not from the SiO₂ lattice, which is why rose quartz is usually cloudy rather than clear. (Specifics from the 2001 Goreva et al. study are cited from memory and unverified.)

MODELFibre density sets a broad absorption near 500 nm plus a gentle scattering haze, both my shapes, through CIE with Bradford. Tap to cut a slab: fibres re-seed. Nesting: clear quartz core, pink fibres around it, void.
