Mineral
Rose quartz is pink quartz. Most pieces are massive, cloudy, without the sharp points of clear quartz. The species is still SiO2. Mohs hardness is 7, recorded on the Handbook of Mineralogy quartz PDF. Webmineral lists rose quartz as rose-colored quartz, a variety of that species. People tumble it, carve it, display it, and wear it. Color is a variety name, not a separate IMA species. Cards below cite the quartz species pages.
