Not a diamond; this specimen appears to be rough quartz or a similar clear mineral/silica crystal rather than crystalline carbon.
Not a diamond; this specimen appears to be rough quartz or a similar clear mineral/silica crystal rather than crystalline carbon. · Rough uncut crystal shard with irregular elongated habit.
Uncut / Raw (Not applicable for standardized cut grades). Cut
Carat
Estimated around 15-20 carats based on visual size (mineral weight equivalent).
Color
Colorless / Near colorless with natural surface weathering.
Clarity
Included / heavily included with internal fractures and surface striations.
Shape
Rough uncut crystal shard with irregular elongated habit.
Overall Assessment
The specimen shown in the image is a rough, unworked mineral crystal (likely quartz) rather than a diamond. It features natural growth striations, internal fractures, and an irregular elongated shape.
Cut Quality
Uncut / Raw (Not applicable for standardized cut grades).
Brilliance
Low brilliance due to lack of facets and presence of internal fractures.
Fire
Minimal dispersion due to raw state and material composition.
Scintillation
Poor scintillation; light does not return uniformly as it would in a faceted gemstone.
Proportions
Irregular raw crystal proportions; standard table/depth percentages do not apply.
Symmetry
Asymmetric natural crystal formation.
Polish
Raw, unpolished natural surface with rough texture and striations.
Fluorescence
Indeterminate without UV testing equipment.
Inclusions
Heavy internal feather fractures, cloudiness, and crystal growth lines visible.
Blemishes
Surface scratches, natural etch marks, and rough chipping along edges.
Origin
Natural geological origin, likely from a pegmatite or hydrothermal vein system.
Treatment Detection
No obvious signs of artificial treatment; appears completely natural.
Estimated Value
Nominal value as a mineral specimen or raw crystal (very low monetary value compared to a diamond).
Certification Estimate
Standard gemological laboratories (GIA, IGI) would issue a gemstone identification report rather than a diamond grading report, likely identifying it as natural quartz.
Investment Potential
Negligible investment potential; valued primarily for educational or decorative specimen purposes.
Similar Diamonds
None, as this is visually and compositionally distinct from diamond.
Setting Suggestions
Best kept as a raw mineral specimen, wire-wrapped crystal pendant, or organic jewelry piece.
Care & Maintenance
Clean gently with warm soapy water and a soft brush; avoid harsh acids or impacts that could propagate internal fractures.
Interesting Facts
Raw quartz crystals often display characteristic striations perpendicular to the prism length, which are clearly visible on this specimen.
