Not a cut diamond; likely rough gemstone material or quartz matrix with localized iridescence
Not a cut diamond; likely rough gemstone material or quartz matrix with localized iridescence · Irregular / Rough aggregate
Not applicable (uncut rough mineral) Cut
Carat
Not applicable for rough matrix material
Color
Brownish grey / Translucent
Clarity
Included / Heavily fractured
Shape
Irregular / Rough aggregate
Overall Assessment
The specimen does not exhibit the characteristics of a faceted gem-grade diamond, representing instead a textured mineral matrix requiring laboratory testing for precise mineral identification
Cut Quality
Not applicable (uncut rough mineral)
Brilliance
Low due to lack of standard facet geometry
Fire
Minimal spectral dispersion visible on localized micro-surfaces
Scintillation
Poor, limited to minor specular reflections
Proportions
Not applicable for unpolished rough mineral
Symmetry
Not applicable for rough material
Polish
Natural rough surface with micro-crystalline texture
Fluorescence
Unable to determine without UV testing
Inclusions
Dense micro-fractures, mineral inclusions, and granular matrix
Blemishes
Natural surface irregularities, pits, and weathering marks
Origin
Natural geological formation, unverified source
Treatment Detection
No obvious visible treatments detected under magnification
Estimated Value
Minimal ornamental or specimen value
Certification Estimate
Standard gemological laboratories would issue a gemstone identification report rather than a diamond grading report
Investment Potential
None; educational or mineral specimen value only
Similar Diamonds
None, as this is not a gemstone-quality diamond
Setting Suggestions
Wire-wrapped or organic bezel settings if used as a mineral specimen jewelry piece
Care & Maintenance
Standard gentle cleaning with mild soap and water; protect from harsh impacts
Interesting Facts
The surface displays subtle iridescent sheen phenomena caused by micro-fractures or thin-film interference
