Natural rough diamond crystal
Natural rough diamond crystal · Rough octahedral/irregular crystal form
Not applicable (uncut rough crystal requiring professional planning and cutting) Cut

Carat
Estimated 1.5 to 2.5 carats based on visual scale against fingers
Color
Near-colorless to faint brownish tint (approx. G-I range)
Clarity
Included (approx. SI1-SI2 range due to visible internal fractures and inclusions)
Shape
Rough octahedral/irregular crystal form
Overall Assessment
An interesting, natural rough diamond crystal displaying characteristic curved faces and natural growth features, holding significant potential if cut and polished skillfully
Cut Quality
Not applicable (uncut rough crystal requiring professional planning and cutting)
Brilliance
Low in rough form; will exhibit high brilliance once properly cut and polished
Fire
Obscured by rough surface texture; expected to show standard dispersion once faceted
Scintillation
Absent in current rough state
Proportions
Natural rough proportions, requires sawing/cleaving and faceting to optimize yield
Symmetry
Natural crystal symmetry showing distorted octahedral faces
Polish
Natural crystalline surface with growth lines (trigons) and rough facets
Fluorescence
Cannot be determined without UV testing
Inclusions
Visible internal feathers, dark crystal inclusions, and stress fractures
Blemishes
Natural surface pitting, rough skin, and minor surface naturals
Origin
Alluvial or primary kimberlite rough deposit
Treatment Detection
No treatments detected; appears completely untreated and natural
Estimated Value
Varies widely based on final cut yield, estimated at several hundred to a few thousand dollars depending on final clarity after cutting
Certification Estimate
GIA or similar major laboratory would grade post-cutting as a polished stone
Investment Potential
Speculative value tied directly to the skill of the diamond cutter who processes the rough
Similar Diamonds
Comparable to unassorted run-of-mine natural diamond rough parcels
Setting Suggestions
Can be custom-set raw in organic artisan jewelry or faceted into a classic round/cushion cut for traditional settings
Care & Maintenance
Store separately to prevent scratching other materials; clean gently with warm soapy water
Interesting Facts
Rough diamonds straight from the earth often look deceptively like ordinary pebbles until examined closely for crystal faces and adamantine luster
