Physical properties
Hardness: 6-7 on Mohs scale; Color: Pink, reddish, with black and white speckles; Luster: Dull to vitreous; Crystal structure: Phaneritic (coarse-grained); Composition: Quartz, Potassium Feldspar, and Biotite mica.
Formation & geological history
Formed from the slow cooling and crystallization of molten magma deep beneath the Earth's surface. This specimen appears as a river stone or glacial cobble, having been rounded by water or ice erosion over thousands of years.
Uses & applications
Used extensively in construction for countertops, monuments, paving stones, and as decorative landscaping gravel.
Geological facts
Granite is the most common rock found in the Earth's continental crust. The pink hue is specifically caused by a high concentration of potassium feldspar (orthoclase).
Field identification & locations
Identified by its visible interlocking crystals of pink, translucent white, and black. Often found in riverbeds, glacial deposits, or mountainous regions. Collectors look for unique vein patterns or large crystal sizes.
