Indeterminate (Likely Quartz or Glass)
Indeterminate (Likely Quartz or Glass) · Rough / Uncut fragment
N/A (Rough material) Cut
Carat
Estimated 2.0-5.0 carats based on size relative to fingers
Color
Colorless to Near-Colorless
Clarity
Transparent with heavy internal fracturing (I-category equivalent)
Shape
Rough / Uncut fragment
Overall Assessment
This specimen lacks the characteristic crystal habit of a diamond. Its transparent, vitreous luster and fracture patterns strongly suggest it is a piece of rough quartz or glass rather than a diamond.
Cut Quality
N/A (Rough material)
Brilliance
Low (typical of uncut material)
Fire
None visible
Scintillation
Minimal scattered light reflections
Proportions
N/A
Symmetry
N/A (Irregular rough)
Polish
N/A (Natural luster or fractured surfaces)
Fluorescence
Cannot be determined from image
Inclusions
Heavy internal fracturing, cleavage planes, and a notable red surface/internal spot
Blemishes
Chipped edges and conchoidal fractures throughout
Origin
Terrestrial mineral (possible Quartz from metamorphic or igneous rock)
Treatment Detection
No obvious treatments; appears to be raw mineral material
Estimated Value
Low (Specimen value only if diamond; high probability of non-diamond mineral)
Certification Estimate
Unlikely to be certified as a diamond; GIA/IGI for rough identification only
Investment Potential
None
Similar Diamonds
Rough diamond macles or industrial grade bort (though this appears more glass-like)
Setting Suggestions
Wire wrap or custom specimen cage if desired as a pendant
Care & Maintenance
Avoid impact as fractures suggest high fragility; clean with warm water
Interesting Facts
The conchoidal (shell-like) fracture pattern is more characteristic of quartz or glass than a diamond's octahedral cleavage.
