Overall Assessment
This is a natural green mineral specimen, not a diamond. It lacks the refractive index, crystal habit, and transparency of a diamond. Its appearance is consistent with a metamorphic rock like green quartzite or phyllite.

None (Raw mineral state)
Brilliance
None (Dull/Matte luster)
Fire
None
Scintillation
None (Subject to mica-like glitter/aventurescence)
Proportions
Asymmetric natural form
Symmetry
Poor (Natural erratic structure)
Polish
Unpolished (Naturally rough surface)
Fluorescence
Unknown without UV testing
Inclusions
Highly included with minerals, likely mica or chromium-rich silicates
Blemishes
Surface pitting and weathering consistent with metamorphic rocks
Origin
Terrestrial rock, possibly Fuchsite or Green Quartzite
Treatment Detection
None apparent; looks like a raw natural mineral
Estimated Value
$1 - $10 (Low value as a decorative stone/rock specimen)
Certification Estimate
Not eligible for GIA Diamond Grading; would require mineral identification report
Investment Potential
Negligible (Standard common mineral)
Similar Diamonds
None (This is not a diamond; it lacks the adamantine luster and crystal structure)
Setting Suggestions
Wire wrapping for use as a pendant or display in a mineral collection
Care & Maintenance
Rinse with water; avoid harsh chemicals as it may be soft or porous
Interesting Facts
The green color is likely due to chromium content within the mineral structure, typical of stones like Fuchsite.
