Natural diamond rough or highly abraded crystal surface
Natural diamond rough or highly abraded crystal surface · Rough crystal / Irregular / Uncut
Not Applicable (Uncut rough crystal) Cut

Carat
Estimated 1.50 - 2.50 ct based on microscopic field view
Color
Near Colorless to Faint Yellow (G-J range estimated from body colour)
Clarity
Included (I1-I3 based on prominent internal fracture lines and surface trigons)
Shape
Rough crystal / Irregular / Uncut
Overall Assessment
This is a natural uncut diamond crystal displaying distinct surface growth features and natural internal fracture planes, awaiting professional cutting to unlock its full optical potential.
Cut Quality
Not Applicable (Uncut rough crystal)
Brilliance
Low (due to unpolished surface and opaque crystal skin)
Fire
Minimal (hidden by rough surface texture)
Scintillation
Poor to none in current rough state
Proportions
Natural crystal growth proportions; depth and table percentages do not apply
Symmetry
Natural crystalline symmetry (octahedral tendency)
Polish
Natural crystal faces (unpolished)
Fluorescence
Inert to Faint Blue (standard assumption requiring UV testing)
Inclusions
Prominent needle-like mineral inclusions, internal cleavage planes, and feather fractures visible
Blemishes
Natural surface etch channels, trigons, and surface abrasions
Origin
Likely alluvial or primary kimberlitic deposit (African or Canadian origin)
Treatment Detection
No treatments detected; completely untreated natural rough diamond
Estimated Value
Depends heavily on cutting yield; estimated rough value $1,000 - $3,000 USD
Certification Estimate
GIA Rough Diamond Evaluation or Kimberley Process documentation
Investment Potential
Moderate, highly dependent on the final polished yield after professional cutting
Similar Diamonds
Standard run-of-mine industrial or lower-gem quality octahedral rough crystals
Setting Suggestions
Requires professional cutting and faceting into a Round Brilliant or Cushion shape before mounting; suitable for bespoke solitaire settings
Care & Maintenance
Store separately from other gemstones to prevent scratching; clean with warm soapy water and soft brush
Interesting Facts
The surface features visible trigons (triangular growth marks) which are characteristic of natural diamond crystal faces.
