Small greenish-gold mineral fragment, possibly olivine (peridot)

Olivine-group silicate, (Mg,Fe)₂SiO₄; identification is uncertain from the image

AI-generated identification · may be incorrect

Tiny, irregular fragment with a translucent olive-green to gold appearance and vitreous luster. If olivine, hardness is 6.5–7 Mohs, with orthorhombic crystals and no prominent cleavage.

Physical properties

Tiny, irregular fragment with a translucent olive-green to gold appearance and vitreous luster. If olivine, hardness is 6.5–7 Mohs, with orthorhombic crystals and no prominent cleavage.

Formation & geological history

Olivine commonly crystallizes in magnesium-rich basalt and mantle rocks; fragments may be released by weathering. Its age and source cannot be determined from the image.

Uses & applications

Gem-quality olivine is cut as peridot; common olivine is also studied as a major mantle mineral and used in some industrial applications.

Geological facts

Peridot is the gem variety of olivine. Similar-looking grains can include other minerals or glass, so appearance alone is not diagnostic.

Field identification & locations

A green color and glassy luster fit olivine, but a close-up, hardness test, and refractive or compositional analysis would be needed to confirm it. Olivine occurs in basalt, peridotite, and some meteorites.
