Physical properties
Hardness: 6-7 on Mohs scale; Color: Pink, reddish-orange, with grey and white grains; Luster: Vitreous to dull; Crystal structure: Phaneritic (coarse-grained); Cleavage: Perfect in feldspar grains, none in quartz; Specific gravity: 2.63 to 2.75
Formation & geological history
Formed through the slow crystallization of magma below Earth's surface. High in potassium feldspars (orthoclase) which give it the pink color. Can range from Precambrian to Cenozoic in age.
Uses & applications
Extensively used in construction for countertops, floor tiles, paving stones, monuments, and as a decorative architectural stone due to its durability.
Geological facts
The pink color comes specifically from the high concentration of potassium feldspar. It is one of the most recognizable rocks on Earth's continental crust and is exceptionally resistant to weathering.
Field identification & locations
Identified by its salt-and-pepper appearance with prominent pink/orange grains and visible glassy quartz crystals. It is found in mountain ranges and continental shields worldwide.
