Physical properties
Hardness: 6.5–7.5 on Mohs scale; Color: Deep red to brownish-red; Luster: Vitreous (glassy); Crystal Structure: Isometric (often dodecahedral); Cleavage: None; Specific Gravity: 3.5–4.3
Formation & geological history
Formed in metamorphic rocks (such as schist and gneiss) under high pressure and temperature, or in certain igneous rocks. They are found globally in various geological ages, often as accessory minerals.
Uses & applications
Primary use is in jewelry as a gemstone and as a high-performance industrial abrasive (sandblasting and water-jet cutting) due to its hardness.
Geological facts
Garnet is the birthstone for January. Throughout history, it was believed to protect travelers and was often used in signet rings in Ancient Rome to seal important documents.
Field identification & locations
Field identification is based on the 'garnet shape' (dodecahedron), lack of cleavage, and its characteristic deep red color. It is commonly found in river sands and metamorphic outcrops in regions like India, Brazil, and the USA.
