Tumbled quartz fragments, likely rose quartz

Quartz (silicon dioxide, SiO₂), possibly iron- or titanium-tinted rose quartz

AI-generated identification · may be incorrect

Hardness 7 Mohs; translucent pale pink to smoky-clear color, vitreous luster, conchoidal fracture, and no cleavage. Crystals are trigonal, though tumbling has removed crystal faces; dark inclusions may be tourmaline, mica, or iron/manganese minerals.

Physical properties

Formation & geological history

Quartz forms in igneous pegmatites, hydrothermal veins, and metamorphic rocks; rose quartz commonly formed in Precambrian pegmatites, often roughly 1 billion years old. These pieces appear cut or tumbled rather than naturally weathered.

Uses & applications

Used for beads, carvings, ornamental objects, metaphysical specimens, and inexpensive jewelry; quartz also has major industrial uses in glass, electronics, and abrasives.

Geological facts

The pink color of rose quartz is commonly linked to microscopic inclusions of dumortierite or related mineral defects. Transparent pink quartz crystals are uncommon; most rose quartz is massive and translucent.

Field identification & locations

Identify with glass-like luster, hardness sufficient to scratch ordinary glass, and conchoidal edges; confirm with a streak test and avoid relying on color alone. Common sources include Brazil, Madagascar, India, South Africa, and the United States.
