Carat
Estimated 2.5 to 3.5 carats
Color
Near-colorless to light brown tint (K-M range approximately)
Clarity
SI1 to SI2 (estimated for rough state with internal features)
Shape
Rough / Uncut irregular elongated crystal form
Overall Assessment
A fascinating, untreated natural rough diamond crystal displaying authentic geological formation features, ideal either as a raw mineral specimen or for specialized custom cut processing.
Cut Quality
Not applicable (Rough, uncut crystal)
Brilliance
Low in rough form due to unpolished faces and lack of optical geometry
Fire
Minimal dispersion visible through natural curved crystal faces
Scintillation
Limited flash effect primarily from natural reflective crystal skins
Proportions
Natural rough proportions, elongated crystal habit
Symmetry
Natural crystalline symmetry showing octahedral/dodecahedral growth lines and striations
Polish
Natural unpolished crystal faces with characteristic trigons and striations
Fluorescence
Indeterminate from visual inspection alone
Inclusions
Internal crystal inclusions, clouds, and feather indicators typical of rough diamond formation
Blemishes
Natural surface textures, etch channels, and growth hillocks
Origin
Likely alluvial or primary kimberlite pipe natural origin (African or Canadian source indicators)
Treatment Detection
No signs of artificial treatment; completely natural untreated rough
Estimated Value
Variable based on cutting yield potential, roughly $1,500 to $3,500 depending on final polished recovery
Certification Estimate
GIA Rough Diamond Evaluation or Kimberley Process Certificate of Origin
Investment Potential
High collector interest for unique natural specimens, moderate for cutting depending on final yield
Similar Diamonds
Other natural industrial or gem-grade rough diamond crystals of comparable size
Setting Suggestions
Raw uncut diamond jewelry setting, bezel setting in yellow or white gold, organic artisanal designs
Care & Maintenance
Standard gentle cleaning with warm soapy water and soft brush; handle carefully to avoid chipping natural cleavage planes
