Natural (Rough Crystal)
Natural (Rough Crystal) · Rough / Uncut Octahedral / Irregular Fragment
Not Applicable (Rough Stone) Cut
Carat
Estimated 2.0 to 3.5 carats
Color
Near-Colorless to Faint Yellow (G-J range)
Clarity
Included (I1-I3 based on visible surface features and internal inclusions)
Shape
Rough / Uncut Octahedral / Irregular Fragment
Overall Assessment
An interesting, natural rough diamond specimen with significant matrix attachment and inclusions, ideal either as a collector's mineral specimen or for custom lapidary cutting to maximize faceted yield
Cut Quality
Not Applicable (Rough Stone)
Brilliance
Low to Moderate due to rough unpolished surface and internal opacity
Fire
Minimal visible fire through raw exterior faces
Scintillation
Limited, as light does not efficiently enter and exit through a cut pavilion
Proportions
Natural rough morphology, unproportioned
Symmetry
Natural Asymmetric Crystal Growth
Polish
Natural Unpolished Crystalline Surface (Trigons and striations visible)
Fluorescence
Cannot be determined visually without UV testing (Likely Medium to Strong Blue if typical for alluvial rough)
Inclusions
Cloudy patches, mineral inclusions, internal fracturing, and heavy brown matrix/skin residue
Blemishes
Natural surface etchings, pitting, cavities, and adhering rough matrix
Origin
Likely Alluvial or Primary Kimberlite Deposit (African or South American origin)
Treatment Detection
No treatments detected; completely untreated natural rough
Estimated Value
$500 - $1,500 depending on final yield after cutting and internal purity
Certification Estimate
GIA or EGL (Origin report recommended for rough stones)
Investment Potential
Moderate, speculative value depending on how much clean material can be faceted out

Setting Suggestions
Organic raw diamond jewelry settings using yellow gold or textured platinum bezels to preserve the natural crystal form
Care & Maintenance
Handle with care to avoid chipping along natural cleavage planes; ultrasonic cleaning acceptable once matrix is removed
Interesting Facts
Displays natural growth features such as striations and potential curved face formations typical of unrefined crustal diamond development
