Not a diamond; this specimen appears to be rough quartz or mineral glass with natural fractures and inclusions. · Rough / Uncut irregular crystal fragment
Not applicable (Rough, un-faceted stone) Cut
Carat
Not applicable / Large mineral specimen
Color
Colorless with brown/iron staining inclusions
Clarity
Included (I3 equivalent based on heavy natural internal fractures and mineral pockets)
Shape
Rough / Uncut irregular crystal fragment
Overall Assessment
The specimen shown in the image is a rough, un-faceted mineral fragment (likely quartz) featuring natural internal fractures and surface staining, completely distinct from a genuine diamond.
Cut Quality
Not applicable (Rough, un-faceted stone)
Brilliance
Low to moderate vitreous luster, limited by internal fracturing
Fire
Minimal dispersion, typical of quartz rather than diamond
Scintillation
Poor due to lack of standard facet symmetry and heavy internal flaws
Proportions
Not applicable to rough stones
Symmetry
Asymmetrical natural crystal form
Polish
Unpolished rough surface with natural cleavage planes and fracture faces
Fluorescence
Inert to faint
Inclusions
Heavy internal fracturing, cleavage planes, and localized iron oxide staining (brownish spots)
Blemishes
Surface chips, natural irregularities, and rough edges
Origin
Natural terrestrial mineral formation (likely quartz or pegmatite pocket origin)
Treatment Detection
No evidence of artificial treatment; purely natural rough state
Estimated Value
Nominal mineral specimen value (less than $10)
Certification Estimate
Standard gemological laboratories (GIA, etc.) would not certify this as a diamond; suitable only for mineralogical identification reports
Investment Potential
None; ornamental or educational value only
Similar Diamonds
None, as this is visually identified as quartz or mineral glass rather than carbon-based diamond
Setting Suggestions
Wire-wrapped pendant or organic raw mineral setting if desired as a rustic jewelry piece
Care & Maintenance
Standard gentle cleaning with warm soapy water; avoid harsh impacts due to internal stress fractures
Interesting Facts
Stones like this are often mistaken for rough diamonds by amateurs due to vitreous luster and transparency, but lack diamond's extreme hardness and cubic crystal system.
