Not a diamond; appears to be green glass or a green mineral/gemstone rough (such as green quartz, tourmaline, or synthetic material)
Not a diamond; appears to be green glass or a green mineral/gemstone rough (such as green quartz, tourmaline, or synthetic material) · Rough / Uncut / Irregular
Not applicable (uncut rough) Cut

Carat
Estimated 2.0 to 3.5 carats based on visual size in hand
Color
Fancy Vivid Green
Clarity
Not applicable to rough material, contains visible inclusions
Shape
Rough / Uncut / Irregular
Overall Assessment
The specimen shown is a vibrant green rough material resting in a hand. It exhibits characteristics inconsistent with rough diamond crystal morphology (such as octahedral or dodecahedral shapes) and is likely a piece of colored glass, slag, or a non-diamond green gemstone.
Cut Quality
Not applicable (uncut rough)
Brilliance
Low due to lack of faceting and rough surface
Fire
Minimal to none in current unpolished state
Scintillation
None
Proportions
Not applicable to raw crystal/rough
Symmetry
Not applicable to rough stone
Polish
Raw / Unpolished
Fluorescence
Unable to determine without UV testing
Inclusions
Internal fractures, bubbles (if glass), or mineral inclusions visible
Blemishes
Surface irregularities, roughness, and natural crystal growth lines or wear
Origin
Natural mineral or synthetic/man-made glass
Treatment Detection
Requires professional spectroscopic and microscopic testing to rule out artificial coloration or coating
Estimated Value
Nominal value (very low if glass, slightly higher if semi-precious mineral rough)
Certification Estimate
Standard gemological labs (GIA, IGI) would issue a colored gemstone identification report, not a diamond grading report
Investment Potential
None; lacks gem-grade diamond qualities and rarity
Similar Diamonds
None, as this is not a diamond
Setting Suggestions
Wire-wrapped pendant or custom bezel setting if polished into a cabochon
Care & Maintenance
Standard handling; avoid harsh chemicals and impact which could fracture the rough material
Interesting Facts
Green is an extremely rare natural color for diamonds (usually caused by natural radiation exposure), but the stone in the image lacks the typical crystal habit of rough diamond
