Not a diamond; appears to be raw quartz, glass, or another crystalline mineral given the conchoidal fracture and lack of standard crystal habit.
Not a diamond; appears to be raw quartz, glass, or another crystalline mineral given the conchoidal fracture and lack of standard crystal habit. · Rough / Raw irregular shape
Uncut / Raw specimen Cut
Carat
Cannot accurately determine without density testing, estimated roughly at 5-10 carats based on visual size.
Color
Colorless / Transparent
Clarity
Included / Heavily flawed due to internal fractures and surface irregularities.
Shape
Rough / Raw irregular shape
Overall Assessment
The specimen shown in the image is a raw, transparent crystalline material featuring conchoidal fracture lines, but it is fundamentally not a diamond. Further physical testing (such as a thermal conductivity probe or scratch test) is recommended to confirm the exact mineral species.
Cut Quality
Uncut / Raw specimen
Brilliance
Low to moderate due to lack of standard facet angles.
Fire
Minimal dispersion due to material composition and lack of precise cutting.
Scintillation
Poor, lacking facet structure to reflect shifting light patterns.
Proportions
N/A - Raw unprocessed mineral specimen
Symmetry
Asymmetrical (Natural raw state)
Polish
Unpolished / Raw surface
Fluorescence
Unknown without UV testing
Inclusions
Internal fractures, possible veil-like inclusions or stress cracks.
Blemishes
Natural rough surface textures, pitting, and possible chips.
Origin
Natural mineral or industrial glass slag, indeterminate without chemical testing.
Treatment Detection
No obvious treatments detected, appears in its raw/natural or unrefined state.
Estimated Value
Nominal / Specimen value only (low economic value if quartz/glass).
Certification Estimate
Not applicable for grading laboratories like GIA or AGS since this is not a gemstone-grade diamond.
Investment Potential
None; this specimen holds no financial investment value as a gemstone.
Similar Diamonds
None, as this specimen lacks diamond characteristics entirely.
Setting Suggestions
Wire-wrapped pendant setting if kept as a raw mineral specimen.
Care & Maintenance
Handle with care to prevent further chipping along internal fracture planes; clean with mild soapy water and a soft brush.
Interesting Facts
Raw quartz and glass often mimic rough diamond or white sapphire to the untrained eye, but lack the hardness (Mohs 10) and specific refractive index of diamond.
