Comments

Rose quartz receives its coloring from fibrous inclusions of a mineral similar to dumortierite. It is always a light to medium pink, but sometimes is influenced by amethyst and picks up a violet shade. Until the 1980’s, when a new deposit was discovered in Madagascar, it was never found completely transparent. Indeed, one of its best uses is for star cabs and spheres.

Stone Sizes

Rose quartz gems are seldom transparent, especially above 20-30 carats. Large spheres of rose quartz are milky at best.
