Physical properties

Hardness: 6 to 7 on Mohs scale. Color: Pink to reddish-pink. Luster: Vitreous to dull. Cleavage: Poor (if quartz/chert) to perfect in 2 directions (if feldspar). Specific gravity: ~2.6-2.7.

Formation & geological history

Forms in granitic pegmatites, hydrothermal veins, or through metamorphic processes where iron oxides or manganese trace elements impart a pink tint to the host mineral.

Uses & applications

Used primarily as decorative polished stones, tumbled pocket stones, landscaping gravel, and for lapidary lap crafts.

Geological facts

Pink minerals like rose quartz, pink orthoclase feldspar, and rhodonite get their vibrant hues from micro-inclusions of manganese, titanium, or iron oxides trapped during crystal growth.

Field identification & locations

Identified by its distinctive pink color, fine-grained microcrystalline or blocky texture, and hardness capable of scratching glass (if quartz- or feldspar-based). Commonly found in gravel beds, pegmatite deposits, and weathered granite outcrops worldwide.
