Natural rough diamond crystal
Natural rough diamond crystal · Rough crystal / Irregular octahedral or elongated form
Not applicable (uncut rough specimen) Cut
Carat
Estimated 2.0 - 3.5 carats (rough)
Color
Near-colorless to light brown tint (K-M range approximately)
Clarity
Included / Industrial to lower ornamental grade due to visible internal inclusions and fractures (I2-I3 equivalent if cut)
Shape
Rough crystal / Irregular octahedral or elongated form
Overall Assessment
This is an authentic, natural rough diamond crystal displaying characteristic surface textures and natural inclusions. While unsuitable for standard high-end faceted jewelry without significant weight loss, it makes a fascinating geological specimen or a unique centerpiece for rustic, raw-diamond jewelry designs.
Cut Quality
Not applicable (uncut rough specimen)
Brilliance
Low to moderate due to rough surface and internal inclusions
Fire
Minimal dispersion in its current rough state
Scintillation
Limited flash due to unpolished, irregular crystal faces
Proportions
Natural rough proportions, asymmetrical crystal habit
Symmetry
Natural crystal symmetry showing distorted growth lines and trigons
Polish
Natural unpolished crystal face with natural etching and surface textures
Fluorescence
Cannot be definitively determined without UV testing, likely Faint to Medium blue if fluorescent
Inclusions
Heavy internal clouding, dark mineral inclusions, and internal feather fractures
Blemishes
Natural surface etchings, trigons, pitting, and surface cavities
Origin
Alluvial or primary kimberlite/lamproite deposit origin
Treatment Detection
No signs of artificial treatment; completely natural untreated rough stone
Estimated Value
Modest collector or industrial value ($100 - $300 depending on exact weight and gem-cutting potential)
Certification Estimate
GIA or similar major lab would issue a Rough Diamond Identification Report or Kimberley Process certificate
Investment Potential
Low investment potential for this specific quality, primarily valued as a mineral specimen or for bespoke rustic jewelry
Similar Diamonds
Other natural unpolished alluvial rough diamond crystals from African, Canadian, or Russian mines
Setting Suggestions
Can be wire-wrapped in raw form using yellow or white gold, or custom-set in an organic, rustic bezel setting
Care & Maintenance
Clean gently with warm soapy water and a soft brush; protect from hard impacts which could exploit internal cleavage planes
Interesting Facts
Rough diamonds preserve the geological history of the Earth's mantle and often display natural growth features like curved crystal faces and triangular etch marks called trigons
