Unidentified pale green mineral fragment
Possibly serpentine, jade, or green quartz; image insufficient for confident identification

Physical properties
Small opaque-to-translucent pale green chip with a likely waxy or dull luster; hardness and crystal structure cannot be determined visually. A hardness, streak, specific-gravity, and cleavage test would be needed.
Formation & geological history
If serpentine, it formed through hydration of ultramafic rocks; if jade, it formed in metamorphic subduction-zone rocks; if quartz, it crystallized from silica-rich fluids. Geological ages vary widely by locality.
Uses & applications
Potentially ornamental or lapidary material, but this fragment is too small and unidentified to assess for jewelry or industrial use.
Geological facts
The color and smooth-looking surface are consistent with several common green minerals, including serpentine, nephrite, jadeite, aventurine, and fluorite.
Field identification & locations
Test cautiously: quartz scratches glass (Mohs 7), jade and serpentine generally do not; serpentine is typically softer (about 2.5–5.5), while jade is tougher and denser. Common sources include California, Wyoming, New Zealand, Myanmar, and China, depending on mineral identity.
