Natural rough diamond crystal
Natural rough diamond crystal · Rough crystal / Uncut octahedron-derived form
Not applicable (Rough, unpolished crystal state) Cut
Carat
Estimated 1.50 to 2.00 carats based on relative visual proportions
Color
Estimated near-colorless to faint tint (approx. G-I range)
Clarity
Included (I1-I2 equivalent due to prominent dark mineral inclusion visible near the top corner)
Shape
Rough crystal / Uncut octahedron-derived form
Overall Assessment
An interesting and genuine natural rough diamond crystal displaying characteristic natural growth features and a distinct dark inclusion. It holds potential for either collector display in its raw state or careful faceting to maximize finished gem weight and clarity.
Cut Quality
Not applicable (Rough, unpolished crystal state)
Brilliance
Limited in rough state; will require professional cutting and polishing to exhibit standard diamond brilliance
Fire
Obscured by rough surfaces; standard dispersion will be unlocked upon proper faceting
Scintillation
Absent in current uncut form due to lack of symmetrical facets
Proportions
Not applicable to rough crystals (no standard table, depth, or angles)
Symmetry
Natural crystal symmetry showing distorted octahedral/dodecahedral growth faces
Polish
Natural crystal face texture (trigons and growth lines may be present under magnification)
Fluorescence
Indeterminate from visual assessment alone, likely inert to faint
Inclusions
Prominent dark crystal inclusion (likely carbon or graphite) near the apex, with potential internal feathering
Blemishes
Natural rough surface features, minor abrasions, and pitting typical of alluvial or primary deposits
Origin
Likely primary kimberlitic or secondary alluvial origin (common in African, Canadian, or Russian deposits)
Treatment Detection
No signs of artificial treatments; completely natural untreated rough specimen
Estimated Value
Variable depending on final cut yield, highly dependent on how the central inclusion affects the finished polished stone
Certification Estimate
GIA or similar major lab would issue a Rough Diamond Report or a diamond grading report post-cut
Investment Potential
Moderate as a raw specimen for collectors; value post-cutting depends heavily on the lapidary's skill in avoiding inclusions
Similar Diamonds
Comparable to standard industrial-to-gem grade run-of-mine rough diamond crystals
Setting Suggestions
Can be preserved in its organic rough state within a custom bezel setting, or cut into a cushion or round brilliant for a classic mounting
Care & Maintenance
Store separately to prevent scratching other softer gemstones; clean with mild soapy water and a soft brush
Interesting Facts
Rough diamonds preserve the natural growth history of the earth, often featuring microscopic fluid inclusions trapped millions of years ago
