Not a diamond; this is a rough green gemstone, visually consistent with green tourmaline or chrome diopside, though further testing is required for definitive identification.
Not a diamond; this is a rough green gemstone, visually consistent with green tourmaline or chrome diopside, though further testing is required for definitive identification. · Uncut rough crystal fragment
Not applicable (uncut raw crystal) Cut
Carat
Estimated 1.5 - 2.5 carats based on visual proportions against human skin
Color
Vivid intense green (Fancy Vivid Green if evaluated under diamond standards)
Clarity
Included to heavily included (raw rough crystal with natural internal fractures and inclusions)
Shape
Uncut rough crystal fragment
Overall Assessment
An attractive raw green crystal fragment displaying vibrant coloration, suitable for mineral collection or custom lapidary work after professional identification
Cut Quality
Not applicable (uncut raw crystal)
Brilliance
Varies by angle due to rough surface and natural transparency
Fire
Low to moderate dispersion characteristic of colored stones rather than diamond
Scintillation
Limited flash due to lack of faceted surfaces
Proportions
Irregular raw crystal dimensions
Symmetry
Asymmetrical raw crystal formation
Polish
Natural rough surface with striated crystal faces and fracture planes
Fluorescence
Unknown without UV testing
Inclusions
Natural internal fractures, veil-like inclusions, and mineral growth tubes typical of raw colored gemstones
Blemishes
Natural surface pitting, striations, and rough edges
Origin
Natural geological formation, likely from pegmatite or metamorphic environments depending on the exact mineral
Treatment Detection
No obvious signs of artificial treatments; appears completely natural as a raw specimen
Estimated Value
Modest value as a raw mineral specimen, highly dependent on exact mineral species
Certification Estimate
Gemological laboratories such as GIA or IGI would issue a colored gemstone identification report rather than a diamond grading report
Investment Potential
Low as an investment; primarily of interest to mineral collectors or lapidaries
Similar Diamonds
None, as this is a colored gemstone rough and not a diamond
Setting Suggestions
Wire-wrapped organic setting or custom bezel setting if cut and polished into a cabochon or faceted gemstone
Care & Maintenance
Handle with care to prevent chipping along natural cleavage planes; avoid ultrasonic cleaners if internal fractures are severe
Interesting Facts
Vibrant green rough crystals are often mistaken for emerald or green diamond by untrained observers
