Natural rough diamond crystal
Natural rough diamond crystal · Rough octahedral/irregular crystalline form
Not applicable (Rough, un-faceted stone) Cut
Carat
Estimated 3.50 to 5.00 carats
Color
Estimated near-colorless to light yellow/brown tint (G-J range)
Clarity
Included (I1-I2 range due to prominent fractures and inclusions)
Shape
Rough octahedral/irregular crystalline form
Overall Assessment
This is an interesting, natural rough diamond crystal displaying characteristic octahedral/dodecahedral growth structures with visible surface inclusions and fractures. It has potential for cutting into a commercial-grade polished diamond, though its numerous internal flaws will limit its final clarity and market value.
Cut Quality
Not applicable (Rough, un-faceted stone)
Brilliance
Low in current rough state; depends entirely on future cutting and polishing
Fire
Minimal dispersion in rough form; will manifest post-facetation
Scintillation
Absent in current state
Proportions
Natural rough proportions, deep and irregular
Symmetry
Natural crystal symmetry, distorted
Polish
Raw, natural crystal faces (some trigons or striations expected)
Fluorescence
Cannot be determined accurately without UV testing (likely inert or faint)
Inclusions
Heavy internal feather fractures, carbon spots, and mineral inclusions
Blemishes
Natural surface etching, rough skin, and possible cavities
Origin
Alluvial or primary kimberlitic deposit (exact mine unknown without provenance data)
Treatment Detection
No signs of artificial treatment; completely natural earth-mined rough
Estimated Value
Depends heavily on yield after cutting, roughly $500 - $1,500 USD for the rough specimen
Certification Estimate
GIA or EGL rough diamond evaluation report
Investment Potential
Moderate as a collector specimen; speculative if purchased for cutting yield
Similar Diamonds
Other industrial or low-gem-quality natural rough diamond crystals
Setting Suggestions
Can be kept as a raw mineral specimen, or custom-cut into a rustic/organic shaped diamond for a unique solitaire ring
Care & Maintenance
Store securely in a soft pouch to prevent chipping along cleavage planes; clean gently with warm soapy water
Interesting Facts
Rough diamonds hold the record for the hardest natural substance on Earth, showing natural crystal growth lines and triangular markings called trigons
