Natural rough mineral crystal, likely quartz, feldspar, or low-grade industrial diamond specimen (needs further gemological testing)
Natural rough mineral crystal, likely quartz, feldspar, or low-grade industrial diamond specimen (needs further gemological testing) · Rough crystal / Uncut crystal mass with natural cleavage planes
Not applicable (Rough, un-faceted specimen) Cut

Carat
Estimated 15 - 25 carats (rough specimen scale)
Color
Off-white to light yellowish tint (K-M range if diamond equivalent)
Clarity
Included / Industrial grade (I3 equivalent with heavy internal fracturing and inclusions)
Shape
Rough crystal / Uncut crystal mass with natural cleavage planes
Overall Assessment
This appears to be a raw, un-faceted mineral specimen (potentially quartz or feldspar rather than gem-quality diamond) displaying natural growth lines, cleavage planes, and heavy internal inclusions.
Cut Quality
Not applicable (Rough, un-faceted specimen)
Brilliance
Low to moderate due to opacity and heavy internal fracturing
Fire
Minimal dispersion observed in the rough, opaque state
Scintillation
Poor sparkle due to lack of standard facet alignment and high inclusion level
Proportions
Non-standard rough dimensions, deep irregular pavilion and crown equivalents
Symmetry
Natural crystal symmetry (Asymmetrical rough form)
Polish
Raw, unpolished natural crystal surfaces
Fluorescence
Cannot be determined without UV testing
Inclusions
Heavy internal fracturing, crystal feathers, cloudiness, and mineral inclusions
Blemishes
Natural surface etching lines, growth features, and rough cleavage damage
Origin
Natural terrestrial geological formation
Treatment Detection
No treatments detected; completely natural raw state
Estimated Value
Nominal specimen or educational value ($10 - $50 depending on mineral composition)
Certification Estimate
Industrial or mineralogical specimen classification (Not standard gem lab certified)
Investment Potential
Low investment potential; valued primarily as a mineral specimen rather than a gemstone
Similar Diamonds
Industrial-grade rough diamond or high-clarity quartz crystal specimens
Setting Suggestions
Wire-wrapped rough stone jewelry or mineral display specimen
Care & Maintenance
Store carefully to prevent chipping along natural cleavage planes; clean gently with warm soapy water
Interesting Facts
Rough crystals show the natural habit of mineral growth before human intervention and faceting
