Physical properties
Hardness: 6-7 (Mohs); Color: Pale pink to reddish with grey and white grains; Luster: Vitreous to dull; Crystal structure: Phaneritic (coarsegrained); Cleavage: Perfect in two directions for feldspar components; Specific gravity: 2.63 to 2.75
Formation & geological history
Formed from the slow crystallization of magma below the Earth's surface. Rich in potassium feldspar which gives the pink hue. Most specimens date back hundreds of millions to billions of years.
Uses & applications
Extensively used in construction as countertops, flooring, monuments, and decorative stone in landscaping. High durability makes it ideal for public buildings.
Geological facts
Granite makes up a large part of the Earth's continental crust. Its pink color specifically indicates a high presence of orthoclase feldspar.
Field identification & locations
Identify by its interlocking crystalline texture and pink/salmon color. Commonly found in mountainous regions or glacial deposits. Look for a 'salt and pepper' look combined with pink tones.
