Natural (Rough Crystal / Industrial-grade appearance)
Natural (Rough Crystal / Industrial-grade appearance) · Rough Octahedral / Irregular Fragment
Not Applicable (Uncut rough stone) Cut
Carat
Estimated 5.00+ carats (large rough specimen)
Color
Estimated J-K or lower (has visible brownish/yellowish tint)
Clarity
Included / Industrial (Significant internal fractures and clouds, likely I2-I3 if faceted)
Shape
Rough Octahedral / Irregular Fragment
Overall Assessment
This is a large, un-faceted natural rough diamond crystal displaying significant internal inclusions and natural cleavage planes. While lacking gem-quality clarity and color for fine jewelry, it serves as an interesting raw mineral specimen showcasing natural diamond crystallography.
Cut Quality
Not Applicable (Uncut rough stone)
Brilliance
Low due to lack of facets and heavy internal inclusions
Fire
Minimal dispersion observed in current rough state
Scintillation
Absent prior to cutting and faceting
Proportions
Natural formation proportions, deep and irregular
Symmetry
Natural rough crystal habit, non-symmetrical
Polish
Raw, unpolished natural crystal surfaces and cleavage planes
Fluorescence
Indeterminate from visual assessment alone
Inclusions
Heavy internal fracturing, cleavage lines, feather inclusions, and cloudiness
Blemishes
Natural surface trigons, rough growth lines, and chipped edges
Origin
Natural alluvial or primary kimberlite deposit (exact origin unknown)
Treatment Detection
No evidence of artificial enhancement; completely natural as-mined state
Estimated Value
Low commercial/gem value; priced primarily as a mineral specimen or industrial-grade rough
Certification Estimate
GIA or EGL (likely issued as a rough diamond report or rejected for standard gem grading due to quality)
Investment Potential
Low investment potential for jewelry; strictly decorative or specimen value
Similar Diamonds
Standard industrial-grade rough diamonds or mineral specimens sold to collectors
Setting Suggestions
Wire-wrapped pendant setting or custom bezel designed to showcase the raw, organic mineral look
Care & Maintenance
Avoid harsh impacts as rough stones with natural cleavage planes can easily fracture along stress lines
Interesting Facts
Rough diamonds often exhibit curved growth lines and triangular surface features called trigons formed deep within the Earth's mantle
