Red garnet crystal cluster
Most likely almandine garnet, Fe₃Al₂(SiO₄)₃; exact species cannot be confirmed from the image alone.
AI-generated identification · may be incorrectDeep red, glassy luster, with blocky crystals and uneven fracture; garnet is typically Mohs 6.5–7.5 and cubic/isometric, with no cleavage. The specimen appears to be a natural, uncut cluster.

Physical properties
Deep red, glassy luster, with blocky crystals and uneven fracture; garnet is typically Mohs 6.5–7.5 and cubic/isometric, with no cleavage. The specimen appears to be a natural, uncut cluster.
Formation & geological history
Garnets commonly form during metamorphism of aluminum-rich rocks, often in schist or gneiss; some also crystallize in igneous rocks. The specimen’s age and source cannot be determined visually.
Uses & applications
Garnet is used as an abrasive and, when transparent and attractive, as a gemstone or mineral-collection specimen.
Geological facts
Garnet is a mineral group rather than a single mineral; color and composition vary widely. Almandine is among the most common red varieties.
Field identification & locations
Look for hard, glassy, red crystals and lack of cleavage; garnets occur worldwide, notably in metamorphic terrains. The image suggests garnet, but a close examination or testing would be needed to verify it.
