Natural rough diamond crystal
Natural rough diamond crystal · Rough crystal (uncut, octahedral/irregular formation)
Not applicable (uncut rough crystal) Cut
Carat
Estimated 1.2 to 1.8 carats based on visual scale against fingers
Color
Estimated near-colorless to faint yellow (G-J range)
Clarity
Estimated Included (I1-I2) with visible internal feathering and inclusions
Shape
Rough crystal (uncut, octahedral/irregular formation)
Overall Assessment
An interesting and authentic natural rough diamond crystal displaying characteristic octahedral growth features, ideal for a custom artisan piece or collection specimen.
Cut Quality
Not applicable (uncut rough crystal)
Brilliance
Low to moderate due to rough, unpolished surfaces diffusing light
Fire
Minimal dispersion visible on raw surface facets
Scintillation
Limited flash effect due to lack of standard pavilion and crown facets
Proportions
Not applicable for rough stones prior to cutting and faceting
Symmetry
Natural octahedral crystal symmetry with curved faces and striplings
Polish
Natural crystal face texture (trigons and striations expected)
Fluorescence
Cannot be determined without UV light testing (typically inert to moderate blue in natural rough)
Inclusions
Visible internal clouds, feathers, and potential carbon spots or mineral inclusions
Blemishes
Natural surface etch channels, growth features, and skin texture
Origin
Likely alluvial or primary kimberlite pipe deposit (African, Canadian, or Russian origin)
Treatment Detection
No signs of artificial treatment; completely natural rough state
Estimated Value
$300 - $800 depending on final yield after cutting and internal purity
Certification Estimate
GIA or EGL rough diamond evaluation report
Investment Potential
Moderate collector appeal as a raw specimen, higher potential if skillfully cut and polished
Similar Diamonds
Comparable natural uncut industrial or lower-gem quality rough crystals
Setting Suggestions
Best suited for custom organic-style rough diamond jewelry, raw pendant, or custom cut-and-polish
Care & Maintenance
Standard ultrasonic cleaning safe, but handle with care to preserve natural crystal edges
Interesting Facts
Rough diamonds retain their geological history, often showing natural triangular growth marks called trigons on their faces
