Natural rough diamond
Natural rough diamond · Rough octahedral / irregular crystal form
Not applicable (Rough, un-cut crystal specimen) Cut

Carat
Estimated 2.50 to 3.50 carats based on visual proportions
Color
Near-colorless to light brown tint (Estimated K-M range)
Clarity
Estimated Included (I1 to I2 range due to visible natural surface inclusions and internal feathers)
Shape
Rough octahedral / irregular crystal form
Overall Assessment
An interesting, substantial natural rough diamond crystal showing raw geological characteristics, ideal for custom cutting or as a collector's mineral specimen
Cut Quality
Not applicable (Rough, un-cut crystal specimen)
Brilliance
Low to moderate due to rough unpolished state and surface texture
Fire
Limited dispersion visible on raw surfaces
Scintillation
Minimal flash effect typical of rough diamond crystal skins
Proportions
Natural rough stone with natural facets, depth and table percentages do not apply
Symmetry
Natural crystal symmetry, distorted octahedral form
Polish
Natural crystal faces (some trigons or striations potentially present)
Fluorescence
Cannot be determined without UV testing, likely None to Faint
Inclusions
Internal feathers, clouds, and mineral crystal inclusions visible
Blemishes
Natural surface etch channels, pits, and rough skin
Origin
Likely alluvial or primary pipe deposit origin (African or Canadian rough source)
Treatment Detection
No signs of artificial treatment; appears completely untreated rough
Estimated Value
Varies widely as a rough specimen, roughly $1,000 to $3,000 depending on cutter yield and final polished weight
Certification Estimate
GIA or similar major gemological laboratory report for rough stones
Investment Potential
Moderate, primarily valued as a collector's mineral specimen or custom lapidary potential
Similar Diamonds
Comparable unpolished alluvial rough diamond specimens of similar size
Setting Suggestions
Can be mounted in a bespoke organic raw-stone bezel setting using yellow or white gold
Care & Maintenance
Store separately from other jewelry to prevent scratching; clean gently with warm soapy water and a soft brush
Interesting Facts
Rough diamonds display natural curved crystal faces and characteristic triangular growth markings known as trigons
