Natural rough diamond crystal with characteristic growth striations and natural surface features.
Natural rough diamond crystal with characteristic growth striations and natural surface features. · Uncut rough elongated crystal form, somewhat irregular tabular or elongated shape.
Not applicable (Rough, unpolished crystal state). Cut
Carat
Estimated between 2.0 to 3.5 carats based on visual dimensions.
Color
Estimated near-colorless to very faint brown/yellow tint (approximately J-K range in rough state).
Clarity
Estimated SI1 to SI2 inclusions visible internally with natural surface fractures/cleavage planes.
Shape
Uncut rough elongated crystal form, somewhat irregular tabular or elongated shape.
Overall Assessment
An intriguing, high-character natural rough diamond crystal featuring distinct growth lines and striations, offering great potential for custom cutting or preservation as a mineral specimen.
Cut Quality
Not applicable (Rough, unpolished crystal state).
Brilliance
Low brilliance due to rough, unpolished state diffusing light.
Fire
Minimal visible dispersion until faceted and polished.
Scintillation
Limited flash effect primarily from natural reflective crystal faces rather than internal facet reflections.
Proportions
N/A for rough stones; displays natural elongated rough crystal morphology.
Symmetry
Natural crystal symmetry showing distortion and natural growth distortion typical of rough stones.
Polish
Natural unpolished crystal faces exhibiting trigons, striations, and rough growth steps.
Fluorescence
Cannot be reliably determined without UV testing, likely inert to faint blue.
Inclusions
Internal feather fractures, cloud clusters, and potential mineral crystal inclusions.
Blemishes
Natural surface etch channels, trigons, pitting, and rough skin.
Origin
Natural alluvial or primary kimberlite pipe origin (Africa or Canada region typically).
Treatment Detection
No treatments detected; appears entirely untreated in its raw natural state.
Estimated Value
Varies by weight and final cut yield, roughly $1,500 to $4,000 as a rough specimen depending on internal clarity.
Certification Estimate
GIA would issue a Diamond Rough Report or grading report post-cutting.
Investment Potential
Moderate value as a collector's raw crystal specimen, higher potential if successfully cut into a high-clarity finished diamond.
Similar Diamonds
Comparable to standard industrial or mid-grade gem-quality rough diamond crystals sold to custom cutters.
Setting Suggestions
Best preserved as a raw mineral specimen in a custom organic-style pendant setting or cut into an elongated fancy shape like an emerald or radiant cut.
Care & Maintenance
Handle with care to prevent chipping along natural cleavage planes; clean gently with warm soapy water and a soft brush.
Interesting Facts
Rough diamonds retain the geological history of the Earth's mantle where they formed billions of years ago under immense pressure.
