N/A (Rough, uncut specimen) Cut
Carat
Cannot be accurately determined by visual estimation alone due to non-standard cut, but appears substantial in weight (likely over 10-20 carats equivalent volume)
Color
Colorless / Transparent
Clarity
Included (contains numerous internal fractures, striations, and inclusions typical of rough quartz crystals)
Shape
Rough crystal / Uncut elongated crystal form
Overall Assessment
The specimen shown is a rough, elongated crystal rather than a diamond. It exhibits characteristic growth striations, natural faces, and internal fracture patterns consistent with quartz or another raw crystalline mineral rather than carbon-based diamond material.
Cut Quality
N/A (Rough, uncut specimen)
Brilliance
Varies by angle due to rough surface light scattering and internal fractures
Fire
Low dispersion typical of quartz or glass rather than diamond
Scintillation
Limited due to lack of faceted surfaces
Proportions
Elongated prismatic crystal habit
Symmetry
Natural asymmetric rough formation
Polish
Raw/Natural crystal faces with conchoidal fracture surfaces
Fluorescence
Unknown without UV testing
Inclusions
Heavy internal feather fractures, striations along the prism faces, and internal cloudiness
Blemishes
Natural surface etching, irregularities, and rough fracture terminations
Origin
Natural geological mineral specimen
Treatment Detection
No obvious treatments observed, appears to be in natural rough state
Estimated Value
Nominal mineral specimen value (low market value compared to gemstones due to common mineral composition)
Certification Estimate
Standard gemological laboratory identification report (not suitable for diamond grading reports like GIA or AGS)
Investment Potential
Low investment value; collected mainly as a mineral specimen or for educational purposes
Similar Diamonds
None (this specimen is not a diamond)
Setting Suggestions
Wire-wrapped or organic bezel setting if used in raw mineral jewelry
Care & Maintenance
Standard care for rough quartz or mineral specimens; avoid harsh acids and impact due to cleavage/fracture planes
Interesting Facts
Displays prominent striations and conchoidal fracture patterns characteristic of natural crystalline quartz growth
