Physical properties
Small, rounded reddish-brown translucent mineral with a vitreous-to-resinous luster; garnet is typically Mohs 6.5–7.5 and cubic, with no cleavage. The photograph alone cannot confirm the species or reliably show its crystal form.
Formation & geological history
Garnets commonly form during metamorphism of aluminum-rich rocks; some occur in igneous rocks and sediments. Their age depends on the host deposit and cannot be determined from the image.
Uses & applications
Gem-quality material is cut for jewelry; lower-grade garnet is used as an abrasive and mineral specimen.
Geological facts
Garnet is a mineral group, not a single species; almandine is among its most common red members.
Field identification & locations
Check for a dense feel, glassy luster, and absence of cleavage; confirm with hardness or laboratory tests rather than color alone. Garnets occur worldwide, including India, Sri Lanka, Madagascar, and the United States.
