Physical properties
Small, rounded, polished dark reddish-brown bead with vitreous luster. Garnet has Mohs hardness 6.5–7.5 and a cubic crystal structure; the image does not show diagnostic cleavage or internal features.
Formation & geological history
Garnet commonly forms during metamorphism of aluminum-rich rocks and occurs in metamorphic and igneous settings. Its age and exact source cannot be determined from the image.
Uses & applications
Used in beads and jewelry, as an abrasive, and as a mineral specimen.
Geological facts
Garnet is a mineral group rather than a single mineral; color and appearance alone cannot confirm the species.
Field identification & locations
The smooth spherical shape suggests a cut and polished bead. Confirm with magnification, refractive-index testing, or gemological analysis; garnets occur worldwide, including India, Sri Lanka, Africa, and the United States.
