Not a diamond; this specimen appears to be raw quartz crystal or optical glass due to the conchoidal fracture patterns and lack of diamond crystal habit.
Not a diamond; this specimen appears to be raw quartz crystal or optical glass due to the conchoidal fracture patterns and lack of diamond crystal habit. · Rough / Raw irregular crystal form
Not applicable (Rough, un-faceted specimen) Cut
Carat
Uncertain due to rough, unpolished state (visual weight estimated over 50 carats equivalent in volume)
Color
Colorless / Transparent
Clarity
I3 / Heavily included with internal fractures, inclusions, and surface damage
Shape
Rough / Raw irregular crystal form
Overall Assessment
The specimen shown in the image is definitively not a diamond. It exhibits characteristic conchoidal fractures, striations, and structural features typical of raw quartz or glass rather than carbon-based diamond crystal habit.
Cut Quality
Not applicable (Rough, un-faceted specimen)
Brilliance
Poor due to lack of standard facet proportions and internal fracturing
Fire
Negligible dispersion
Scintillation
Minimal, localized flash effects from internal fracture planes
Proportions
Not applicable for rough material
Symmetry
Asymmetrical (Natural rough formation)
Polish
Raw / Natural cleavage and fracture surfaces
Fluorescence
None observed
Inclusions
Extensive internal fractures, feathers, and trapped mineral residues
Blemishes
Chips, rough edges, conchoidal fracture ripples, and surface scratches
Origin
Likely natural mineral specimen (Quartz), origin indeterminate without spectroscopy
Treatment Detection
No signs of enhancement; appears entirely untreated raw mineral
Estimated Value
Nominal value as a mineral specimen or raw quartz piece (under $50 USD)
Certification Estimate
Not eligible for diamond certification (would require gemological laboratory report for quartz/mineral identification)
Investment Potential
None; ornamental or mineral specimen value only
Similar Diamonds
None (As this is not a diamond)
Setting Suggestions
Wire-wrapping or bespoke organic bezel setting if polished into a cabochon or specimen display
Care & Maintenance
Handle with care to prevent further chipping along fracture lines; clean with warm soapy water and a soft brush
Interesting Facts
Conchoidal fracture is characteristic of quartz and glass, clearly distinguishing it from the octahedral cleavage of diamond.
