Other physical properties of rose quartz include a specific gravity of 2.65, an index of refraction of 1.54 and a vitreous luster. Individual grains of crystals are distinguishable, which means rose quartz is a macrocrystalline variety of quartz. Some gemstones have rutile crystals aligned 120 degrees apart to form a star-like shape within the mineral. This effect is called asterism.

Rose quartz is the state mineral of South Dakota. The rock is mined in the Black Hills region near the town of Custer. Maine also has rose quartz mines. The pink silicate is primarily found in Brazil, but veins also exist in South Africa, Madagascar, Mozambique, India and the United States.
