Physical properties
Hardness: 6-7 on Mohs scale; Color: Cream, gold, tan with brown/burgundy garnet speckles and dark mica veins; Luster: Vitreous to pearly when polished; Texture: Phaneritic (coarse-grained).
Formation & geological history
Formed deep underground by the slow crystallization of magma (plutonic igneous rock). Widely quarried in places like Brazil.
Uses & applications
Used extensively in architecture and interior design for kitchen countertops, bathroom vanities, flooring, and decorative stonework.
Geological facts
Granite is one of the most durable natural stones on Earth, forming much of the continental crust. The small dark reddish spots in this specific variety are often natural garnet inclusions.
Field identification & locations
Identified by its visible interlocking crystals of quartz, feldspar, and dark minerals. Extremely common in residential construction as polished slabs.
