QUARTZ (var. PINK)
HISTORY, NAME, LOCALITIES: The rare, pink, crystalline variety of quartz was unknown until the 1930s. Its name alludes to its color. Small quantities of pink quartz are occasionally found in Maine, but the pegmatites of Brazil are the only significant source of specimens.
MINERALOGY, PROPERTIES, OCCURRENCE: The physical properties of pink quartz are the same as those of quartz [silicon dioxide, SiO2]. Its crystal form and pale-pink to rose-red colors are diagnostic. Its colors are caused when phosphorus and aluminum replace silicon in the quartz-crystal lattice to form color centers that are then subjected to natural geophysical radiation. Pink quartz, which occurs as short-to-long, horizontally striated, hexagonal, prismatic crystals with pyramidal terminations and good transparency, is found in thin veins within phosphorus-rich granite pegmatites. Pink quartz has a Mohs hardness of 7.0, conchoidal fracture, vitreous luster, and a specific gravity of 2.65. Crystalline pink quartz must not be confused with massive rose quartz.
METAPHYSICAL PROPERTIES, LORE, USES: According to metaphysical beliefs, pink quartz is a stone of love that helps in all matters related to love, raises self-esteem and feelings of self-worth, relieves stress, and promotes inner peace. Pink quartz is occasionally faceted into collectors’ gems, but is too rare for use in jewelry. Almost all pink quartz is used for specimens only.
COLLECTORS’ INFORMATION: Pink quartz is collected for its great rarity, pleasing pink colors, and well-developed crystals.
