Natural diamond rough crystal (or potentially quartz/glass due to irregular structure, but evaluated as a raw mineral specimen)
Natural diamond rough crystal (or potentially quartz/glass due to irregular structure, but evaluated as a raw mineral specimen) · Raw, uncut, irregular crystal form (Rough)
Not applicable (uncut rough stone) Cut
Carat
Estimated 15-25 carats based on visual dimensions
Color
Near-colorless to light yellow tint (Estimated J-K range)
Clarity
Included (I1-I3) with visible internal feather fractures and natural crystal inclusions
Shape
Raw, uncut, irregular crystal form (Rough)
Overall Assessment
An intriguing, unpolished natural crystal specimen displaying characteristic rough morphology, internal fractures, and natural surface textures requiring professional gemological equipment (like a thermal diamond tester and FTIR spectrometer) to definitively separate from quartz or glass lookalikes.
Cut Quality
Not applicable (uncut rough stone)
Brilliance
Low to moderate due to raw, unpolished surface and internal fractures
Fire
Minimal dispersion observed in current rough state
Scintillation
Limited, reflecting light irregularly off natural crystal faces and internal planes
Proportions
Irregular raw specimen with natural octahedral or distorted crystal planes
Symmetry
Natural asymmetrical growth formation
Polish
Raw natural crystal faces, untreated by gem cutting
Fluorescence
Indeterminate from visual assessment alone
Inclusions
Heavy internal feathers, cloudiness, and crystal inclusions typical of raw diamond rough
Blemishes
Natural surface trigons, pitting, and rough skin textures typical of unpolished stones
Origin
Alluvial deposit or primary kimberlite pipe origin typical of natural rough
Treatment Detection
No obvious signs of artificial enhancement; appears in a completely natural, unpolished state
Estimated Value
Varies widely based on actual composition, weight, and industrial vs. gem-quality status; rough specimens of this type require professional tactile testing
Certification Estimate
GIA or similar major lab if submitted for rough grading, though typically sold by weight at tenders
Investment Potential
High speculative value as a raw collector's mineral specimen rather than a standard cut gemstone
Similar Diamonds

Setting Suggestions
Best preserved as a raw mineral specimen in a custom organic wire-wrap or bespoke raw-stone prong setting
Care & Maintenance
Store separately to prevent scratching other items; clean gently with warm soapy water and a soft brush
Interesting Facts
Raw diamond crystals often display natural triangular markings called trigons on their faces formed during upward migration through the earth's mantle
