Pale green rough mineral fragment, possibly amazonite

Unconfirmed; possibly amazonite, a green variety of microcline feldspar (KAlSi₃O₈)

AI-generated identification · may be incorrect

The small, opaque pale blue-green fragment has a matte to slightly vitreous surface and irregular fracture. If amazonite, it has Mohs hardness 6–6.5, a triclinic crystal structure, and two nearly perpendicular cleavage directions; the photo is insufficient for reliable identification.

Physical properties

The small, opaque pale blue-green fragment has a matte to slightly vitreous surface and irregular fracture. If amazonite, it has Mohs hardness 6–6.5, a triclinic crystal structure, and two nearly perpendicular cleavage directions; the photo is insufficient for reliable identification.

Formation & geological history

Amazonite forms in potassium-rich granitic pegmatites as the rock cools and crystallizes; such deposits occur in several geological ages worldwide. A specimen’s age and origin cannot be determined from this image.

Uses & applications

Amazonite is used for cabochons, beads, carvings, and ornamental objects; rough fragments are mainly collected or used decoratively.

Geological facts

Amazonite’s distinctive green-blue color is associated with trace elements and structural defects in feldspar; color alone does not confirm the identification.

Field identification & locations

Check for feldspar cleavage and hardness, and compare with other pale green minerals; locality information or testing would be needed to identify it confidently. Amazonite is found in pegmatites, including deposits in Colorado, Russia, and Madagascar.
