Translucent, coarse-grained variety of the silica mineral quartz found in pegmatites. Rose quartz is valued for its pale to rich pink colour, which is due to very small amounts of titanium. It has been carved since early times and has been faceted to provide gems of good brilliance. Its milky aspect is attributed to tiny, needlelike inclusions of rutile, which, when oriented, give the polished stone an asterism (optical phenomenon of a star-shaped figure) like that found in sapphire, but not as sharp or intense. Rose quartz occurs in Brazil, Madagascar, Sweden, Namibia, California, and Maine, among other sites.
