Overall Assessment
This is a large, natural, unpolished diamond rough specimen displaying significant internal inclusions, natural cleavage planes, and fractures, classifying it as industrial grade or a raw mineral collectible rather than a cut gemstone.
Cut Quality
Not Applicable (Uncut rough stone)
Brilliance
Low due to heavy internal fracturing and lack of optical cut facets
Fire
Minimal due to cloudy and heavily included interior
Scintillation
Poor, light is scattered internally rather than returned properly
Proportions
Natural rough proportions, deep and irregular
Symmetry
Natural asymmetrical crystal formation
Polish
Raw, unpolished surface with natural growth features
Fluorescence
Cannot determine visually (requires UV testing)
Inclusions
Heavy internal feather fractures, mineral inclusions, clouds, and dark spotting
Blemishes
Natural surface etching, trigons, rough skin, and breakage facets
Origin
Natural alluvial or primary kimberlite deposit origin
Treatment Detection
No signs of artificial treatment; completely untreated natural rough
Estimated Value
Low commercial value as a gemstone; valued primarily as a mineral specimen or for industrial use
Certification Estimate
Gemological laboratories would likely grade this as Industrial Grade or Mineral Specimen rather than Gem Quality
Investment Potential
Low investment potential for jewelry; strictly collectible mineral specimen value
Similar Diamonds
Other low-grade industrial or specimen-grade rough diamonds
Setting Suggestions
Not suitable for standard jewelry settings unless wire-wrapped as a raw mineral specimen
Care & Maintenance
Handle with care to avoid breaking along natural cleavage planes
Interesting Facts
Most mined diamonds (around 80%) are of industrial grade rather than gem quality, making specimens like this common in nature
