Rough Natural Diamond
Rough Natural Diamond · Uncut Rough Crystal / Irregular Shape
Not Applicable (Uncut Rough) Cut
Carat
Estimated 2.50 - 3.50 carats based on visual scale against fingers
Color
Cannot be accurately determined from silhouette/backlit image; appears opaque or dark in this lighting condition
Clarity
Not determinable from external silhouette; rough crystals typically contain internal natural inclusions
Shape
Uncut Rough Crystal / Irregular Shape
Overall Assessment
An interesting, naturally formed rough diamond crystal captured in silhouette against the sky, requiring specialized gemological testing for precise color, clarity, and valuation.
Cut Quality
Not Applicable (Uncut Rough)
Brilliance
None (rough, unfaceted surface prevents internal light reflection)
Fire
None in current rough state
Scintillation
None
Proportions
Natural rough proportions, no facets or standard pavilion/crown angles
Symmetry
Natural crystal growth symmetry (likely octahedral or distorted dodecahedral habit)
Polish
Natural crystal faces (trigons or rough skin), unpolished
Fluorescence
Cannot be assessed without UV lighting testing
Inclusions
Internal natural mineral inclusions likely present (e.g., carbon spots, clouds)
Blemishes
Natural surface features, resorption lines, and rough skin typical of unworked crystals
Origin
Natural primary deposit (kimberlite/lamproite) or secondary alluvial deposit
Treatment Detection
No treatments apparent; standard untreated rough crystal
Estimated Value
Varies widely depending on internal clarity, color, and eventual cut yield; rough industrial-to-gem grade value range
Certification Estimate
GIA or similar major laboratory would issue a Rough Diamond Report verifying natural origin
Investment Potential
Held primarily as a collector's specimen or speculative cuttable rough
Similar Diamonds
Comparable to unworked natural run-of-mine gem-quality rough diamond crystals
Setting Suggestions
Can be set raw in organic or rustic bespoke jewelry using bezel or prong settings designed for rough stones
Care & Maintenance
Store separately to avoid scratching other jewelry; clean gently with warm soapy water and a soft brush
Interesting Facts
Rough diamonds hold the untouched geological history of the Earth's mantle before human cutting and polishing
