Natural diamond rough crystal, likely a boart or industrial-grade specimen showing natural curved growth features
Natural diamond rough crystal, likely a boart or industrial-grade specimen showing natural curved growth features · Rough crystal / Natural rounded dodecahedral or macle-like formation
Not applicable (uncut raw crystal formation) Cut
Carat
Estimated at approximately 0.50 to 0.80 carats based on visual size relative to fingers
Color
Off-white to light yellow / gray tint typical of unpolished industrial or lower quality rough
Clarity
I2 - I3 (Included), containing substantial internal clouds, inclusions, and natural structural irregularities
Shape
Rough crystal / Natural rounded dodecahedral or macle-like formation
Overall Assessment
An interesting natural rough diamond crystal specimen displaying characteristic growth features and lower clarity, highly suitable for mineral collectors or unconventional raw jewelry designs
Cut Quality
Not applicable (uncut raw crystal formation)
Brilliance
Very low due to the rough, unpolished surface and internal clouding scattering light
Fire
Minimal to none due to lack of standard gemstone facets and opaque nature
Scintillation
Absent due to opaque and rough surface texture
Proportions
Irregular natural crystal proportions, non-standard geometry
Symmetry
Natural asymmetrical crystallization typical of unworked mineral specimens
Polish
Raw, unpolished surface showing natural crystal skin, striations, and rounded growth features
Fluorescence
Cannot be definitively determined without UV testing, though typical untreated rough may show faint yellow or blue
Inclusions
Heavy internal clouding, crystal inclusions, and micro-fracturing visible throughout
Blemishes
Natural surface trigons, pitting, and irregular growth lines typical of rough diamonds
Origin
Alluvial or primary kimberlite deposit rough, non-specific geographic origin
Treatment Detection
No signs of enhancement or artificial treatments; completely natural state
Estimated Value
Nominal value as a mineral specimen or industrial abrasive, typically under $50 USD
Certification Estimate
Typically not submitted to major labs like GIA or AGS for grading; classified as industrial grade rough
Investment Potential
Low investment potential; valued primarily as a curiosity or educational mineral sample rather than a store of wealth
Similar Diamonds
Industrial grade rough diamonds, uncut mineral specimens, or low-tier diamond boart
Setting Suggestions
Best showcased as a raw, organic mineral specimen in a custom wire-wrap or bezel setting for unique jewelry
Care & Maintenance
Standard cleaning with warm soapy water and a soft brush; protect from harsh impacts despite high hardness to prevent cleavage along natural planes
Interesting Facts
Rough diamonds often exhibit curved crystal faces and rounded edges due to dissolution processes in the earth's mantle before reaching the surface
