Natural Rough Diamond
Natural Rough Diamond · Rough Crystal / Elongated Macle or Fragment
Not applicable (Rough, un-cut stone requiring professional planning) Cut
Carat
Estimated 3.5 to 4.5 carats based on visual proportions
Color
Near-colorless to faint yellow/brown tint (approx. G-I range)
Clarity
SI1 to SI2 equivalent for a rough stone, with natural internal characteristics
Shape
Rough Crystal / Elongated Macle or Fragment
Overall Assessment
An impressive natural rough diamond crystal with good clarity and transparency, offering excellent potential for a custom-cut faceted gemstone or a unique raw-gem jewelry piece
Cut Quality
Not applicable (Rough, un-cut stone requiring professional planning)
Brilliance
Limited in rough form, but exhibits localized surface reflectivity and transparency
Fire
Minimal dispersion observed due to natural unpolished crystal faces
Scintillation
Absent in rough state; will develop significantly upon proper cutting and faceting
Proportions
Elongated crystal habit with natural growth features, requiring custom cut planning
Symmetry
Natural crystalline symmetry, elongated octahedral or distorted growth form
Polish
Natural rough crystal faces (trigons and striations visible)
Fluorescence
Indeterminate from visual assessment (typically tested under UV)
Inclusions
Internal clouds, feather-like cleavage planes, and localized pinpoint inclusions
Blemishes
Natural surface etching, trigons, and surface graining typical of rough crystals
Origin
Likely alluvial or primary kimberlitic pipe origin (Africa or Canada)
Treatment Detection
No signs of artificial treatment; completely natural untreated rough
Estimated Value
Varies widely based on final cut yield, estimated between $3,000 to $6,000 USD in rough form
Certification Estimate
GIA or HRD would issue a rough diamond report or diamond dossier upon cutting
Investment Potential
Good potential for custom cutter/investor who can maximize yield and polish a high-grade finished stone
Similar Diamonds
Comparable to high-clarity natural rough diamond parcels originating from major African mines
Setting Suggestions
Can be kept as a unique raw crystal pendant, or cut into an elongated step-cut (Emerald or Baguette) or Radiant shape
Care & Maintenance
Store separately to prevent scratching other jewelry; clean gently with warm soapy water and a soft brush
Interesting Facts
Rough diamonds retain the geological memory of their journey from the Earth's mantle, often featuring natural growth triangles called trigons on their faces
