Natural (Rough Crystal / Bort)
Natural (Rough Crystal / Bort) · Uncut / Rough Crystalline Form
Not Applicable (Uncut rough specimen) Cut

Carat
Estimated 15.0+ carats (large rough specimen)
Color
K-M (Light yellow-brownish tint common in lower-grade industrial rough)
Clarity
I3 (Heavy inclusions, heavy fracturing, industrial grade)
Shape
Uncut / Rough Crystalline Form
Overall Assessment
A substantial natural rough diamond specimen exhibiting significant internal fracturing and coloration, suitable primarily for mineral collections or industrial application rather than fine jewelry cutting
Cut Quality
Not Applicable (Uncut rough specimen)
Brilliance
Poor (opaque to translucent rough crystal lacking faceted optical return)
Fire
Minimal to none due to lack of standard facet angles
Scintillation
None
Proportions
Not Applicable (Uncut rough specimen)
Symmetry
Natural asymmetrical crystalline growth
Polish
Natural unpolished surface with uneven fracture planes
Fluorescence
Indeterminate from visual assessment alone
Inclusions
Extensive internal fracturing, cleavage planes, and mineral inclusions (such as iron oxide staining)
Blemishes
Natural surface irregularities, rough ridges, and pitting
Origin
Natural primary or secondary deposit (alluvial or kimberlitic rough)
Treatment Detection
None detected (untreated natural rough)
Estimated Value
Low commercial/industrial value (specimen or lower-grade industrial use)
Certification Estimate
Industrial evaluation or rough sorting rather than standard gemological grading (e.g., GIA Rough Grading report if applicable, though typically uncertified)
Investment Potential
Minimal as a financial investment; collectible as a raw mineral specimen only
Similar Diamonds
Industrial-grade rough diamond parcels and low-clarity gemological display specimens
Setting Suggestions
Display raw as a mineral specimen in a custom wire-wrap or bezel setting for raw crystals
Care & Maintenance
Handle with care to prevent further cleavage along natural fracture lines; clean gently with warm soapy water
Interesting Facts
Most mined diamonds globally are industrial grade like this specimen, used for abrasive cutting and drilling rather than jewelry
