Natural rough mineral (Likely quartz, beryl, or tourmaline, but not a gem-quality diamond)
Natural rough mineral (Likely quartz, beryl, or tourmaline, but not a gem-quality diamond) · Uncut rough mineral crystal with conchoidal fractures
Not applicable (Rough, unpolished mineral specimen) Cut
Carat
Exceeds standard carat measurements as rough specimen (approx. 15-20+ carats)
Color
Faint pinkish tint / color-zoned with mineral inclusions
Clarity
Included / heavily fractured (I3 equivalent if graded)
Shape
Uncut rough mineral crystal with conchoidal fractures
Overall Assessment
The specimen shown in the image is not a diamond. It is a natural, heavily fractured rough mineral crystal with distinct conchoidal fracture patterns and matrix inclusions. It holds value as a mineral specimen rather than a faceted gemstone.
Cut Quality
Not applicable (Rough, unpolished mineral specimen)
Brilliance
Poor due to lack of standard facet alignment and heavy internal fractures
Fire
Minimal dispersion observed in current rough state
Scintillation
Negligible flash play due to opaque and fractured internal structure
Proportions
Irregular rough proportions, non-standard geometric form
Symmetry
Asymmetrical natural crystal formation
Polish
Raw, unpolished natural surface with conchoidal fracture planes
Fluorescence
Unknown without UV testing
Inclusions
Heavy internal fracturing, cleavage planes, and dark mineral particulate inclusions
Blemishes
Natural surface roughness, etching marks, and fracture lines
Origin
Natural geological pegmatite or hydrothermal vein deposit
Treatment Detection
No treatments detected; appears entirely natural rough material
Estimated Value
Nominal mineral specimen value ($10 - $50 USD depending on exact mineral type)
Certification Estimate
Would not receive standard diamond certification from GIA/AGS as this is not a diamond
Investment Potential
Low investment potential; sold primarily as a mineral specimen rather than a gemstone
Similar Diamonds
None, as this visually lacks the crystalline structure and optical properties of a diamond
Setting Suggestions
Wire-wrapped organic mineral setting or display specimen mount
Care & Maintenance
Store carefully to avoid expanding existing internal fractures; clean gently with warm soapy water and a soft brush
Interesting Facts
The specimen exhibits pronounced conchoidal fracturing and striations typical of crystalline quartz or tourmaline rather than the octahedral habit of rough diamond
