Natural rough diamond
Natural rough diamond · Uncut rough octahedral or irregular crystal habit
Not applicable for rough stones Cut
Carat
Estimated 1.5 to 2.5 carats
Color
Near-colorless with slight brownish tint (approx. K-M on D-Z scale)
Clarity
Included (approx. I1-I2)
Shape
Uncut rough octahedral or irregular crystal habit
Overall Assessment
An interesting, natural rough diamond crystal displaying characteristic surface features and internal inclusions, offering potential for custom lapidary work or as a raw specimen piece.
Cut Quality
Not applicable for rough stones
Brilliance
Limited in current rough state; glassy to greasy luster
Fire
Minimal dispersion observed in rough, unpolished condition
Scintillation
Low to moderate light return from natural crystal faces
Proportions
Natural rough proportions, deep and irregular
Symmetry
Natural crystal symmetry, asymmetric due to natural growth and abrasion
Polish
Natural crystal faces (trigons), unpolished rough state
Fluorescence
Cannot be definitively determined from visual assessment alone, likely inert to moderate blue
Inclusions
Internal carbon spots, feathers, and cloud-like inclusions visible
Blemishes
Natural surface etch channels, trigons, and surface graining
Origin
Alluvial or primary kimberlite deposit; visual characteristics alone cannot confirm exact mine origin
Treatment Detection
No signs of enhancement; completely untreated natural rough
Estimated Value
Varies significantly depending on potential yield after cutting; rough value lower than polished equivalent
Certification Estimate
Requires professional laboratory grading (GIA or EGL) once cut and polished
Investment Potential
High speculative value based on potential cut yield, but subject to cutting loss risks
Similar Diamonds
Other alluvial or mine-run rough diamond crystals of comparable size
Setting Suggestions
Can be set raw in a custom organic bezel or wire-wrap setting, or cut into a cushion or pear shape
Care & Maintenance
Durable like all diamonds (Mohs 10), but rough edges can catch on fabrics; clean with warm soapy water and a soft brush
Interesting Facts
Rough diamonds retain the geological journey from deep within the Earth's mantle, displaying natural growth marks called trigons
