Natural Rough Diamond Crystal
Natural Rough Diamond Crystal · Rough Crystal / Uncut Octahedral/Dodecahedral Fragment
Not Applicable (Uncut rough stone) Cut
Carat
Estimated 2.5 - 3.5 carats
Color
Faint greenish-yellow to off-white
Clarity
Included (I1 - I3 equivalent due to numerous surface-reaching fractures and dark inclusions)
Shape
Rough Crystal / Uncut Octahedral/Dodecahedral Fragment
Overall Assessment
An interesting and tactile natural rough diamond crystal displaying characteristic surface etchings and inclusions, highly suitable for mineral collections or specialized artisan jewelry rather than traditional high-end faceted use
Cut Quality
Not Applicable (Uncut rough stone)
Brilliance
Low to moderate due to rough surfaces and internal inclusions
Fire
Minimal dispersion visible through the rough unpolished surface
Scintillation
Poor sparkle until properly cut and faceted by a lapidary
Proportions
Irregular rough dimensions; depth and table percentages do not apply
Symmetry
Natural asymmetrical crystal formation
Polish
Natural crystalline surface with growth lines and etch channels
Fluorescence
Indeterminate visually, likely none to moderate blue
Inclusions
Heavy internal feathers, cloudiness, and dark carbon/mineral spots trapped near the surface and edges
Blemishes
Natural surface etchings, trigons, pitting, and rough edge chipping along cleavage planes
Origin
Likely alluvial or primary kimberlite pipe deposit, African or Russian origin
Treatment Detection
None detected; completely untreated natural rough
Estimated Value
Modest value as an industrial or specimen-grade rough stone ($100 - $300)
Certification Estimate
GIA or similar major lab would grade it as a natural rough diamond specimen
Investment Potential
Low investment value for jewelry; primarily of interest to mineral collectors or lapidaries
Similar Diamonds
Other low-clarity industrial or specimen-grade rough diamond crystals
Setting Suggestions
Best preserved as a raw mineral specimen in a custom wire-wrap or organic bezel setting
Care & Maintenance
Store separately from other hard stones to prevent scratching; clean gently with warm soapy water and a soft brush
Interesting Facts
Rough diamonds retain their natural crystal skin and growth marks (trigons) formed deep within the Earth's mantle before being brought to the surface
