Not a diamond (appears to be green glass, slag, or a non-diamond rough mineral like green tourmaline or fluorite given the conchoidal fracture and deep green color)
Not a diamond (appears to be green glass, slag, or a non-diamond rough mineral like green tourmaline or fluorite given the conchoidal fracture and deep green color) · Uncut rough / Crystalline fragment
N/A (Rough, uncut state) Cut
Carat
Estimated 2.0 to 3.5 carats equivalent volume
Color
Fancy Deep Green
Clarity
Included (Contains visible internal striations and fractures)
Shape
Uncut rough / Crystalline fragment
Overall Assessment
The specimen shown in the image is not a diamond. It displays characteristics inconsistent with diamond, such as irregular green coloration and fracture patterns typical of glass or alternative green minerals. Professional gemological testing (refractive index, thermal inertia) is strongly recommended for definitive identification.
Cut Quality
N/A (Rough, uncut state)
Brilliance
Low due to lack of standard facet angles and rough surface
Fire
Minimal to none
Scintillation
Poor due to raw, unfaceted state
Proportions
Elongated irregular crystal habit
Symmetry
Asymmetrical rough crystal form
Polish
Natural rough surface / Unpolished
Fluorescence
Unknown (requires UV testing)
Inclusions
Feathers, fractures, and internal growth structures visible
Blemishes
Surface pitting and natural rough texture
Origin
Synthetic or natural mineral rough (unverified)
Treatment Detection
Visual inspection suggests potential mold marks or cooling lines typical of glass, though advanced testing needed
Estimated Value
Nominal value (decorative or mineral specimen value, essentially negligible if glass)
Certification Estimate
Not applicable for grading by major diamond laboratories like GIA or IGI
Investment Potential
None as an investment gemstone
Similar Diamonds
None, as this specimen does not exhibit diamond properties
Setting Suggestions
Wire-wrapped pendant setting if desired as a raw mineral specimen
Care & Maintenance
Handle with care to prevent chipping if glass or brittle mineral
Interesting Facts
Natural green diamonds are extremely rare and typically colored by natural radiation, whereas green rough stones of this transparency are usually other minerals like tourmaline or synthetic glass
