Physical properties
Mohs hardness of 7; waxy to vitreous luster; translucent reddish-pink to peach color due to iron oxide micro-inclusions; trigonal crystal system; fracture is conchoidal.
Formation & geological history
Forms through hydrothermal processes or within pegmatites where silica-rich fluids precipitate quartz containing hematite or goethite inclusions.
Uses & applications
Popular for lapidary work, decorative landscaping, crystal healing crafts, pocket stones, and jewelry like bead necklaces.
Geological facts
Peach or pink quartz gets its warm color from microscopic traces of iron minerals (like hematite or goethite) trapped during crystallization, unlike rose quartz which is colored by titanium, iron, or manganese micro-fibers.
Field identification & locations
Identified by its hardness (scratches glass), waxy polished surface, smooth rounded river/tumble shape, and warm reddish-tan transparency. Widely available globally.
