Overall Assessment
This is a raw, uncut natural diamond crystal featuring heavy internal inclusions and a natural, unpolished surface. While it lacks the fire and brilliance of a faceted diamond, it possesses unique organic charm as an authentic piece of Earth's geology.
Cut Quality
Not applicable (Rough crystal, uncut)
Brilliance
Low to moderate due to rough surface and inclusions
Fire
Limited due to rough transparency and color tint
Scintillation
Poor, as it lacks standard facet patterns
Proportions
Natural rough geometry; deep and unoptimized
Symmetry
Natural asymmetric crystal growth forms
Polish
Natural crystal faces (octahedral/dodecahedral or etched surfaces)
Fluorescence
Indeterminate from visual assessment alone
Inclusions
Heavy carbon spots, cloudiness, feathers, and dark mineral inclusions visible throughout
Blemishes
Natural surface pitting, trigons (growth marks), and rough skin
Origin
Likely alluvial or primary pipe deposit from African, Russian, or South American origin
Treatment Detection
No evidence of artificial enhancement; completely untreated natural rough
Estimated Value
Low commercial value, primarily valued as a specimen piece or low-grade industrial/cuttable rough ($50 - $200 USD depending on exact weight and purity)
Certification Estimate
GIA or local gemological lab (would likely receive a rough diamond report or identification report rather than a standard cut diamond grading report)
Investment Potential
Very low investment potential; strictly a collector's specimen or novelty item
Similar Diamonds
Other low-grade industrial or uncut gemstone-grade diamond crystals
Setting Suggestions
Best suited for organic, rustic, or raw-diamond jewelry settings such as a bezel setting in yellow or rose gold
Care & Maintenance
Standard gentle cleaning with warm soapy water and a soft brush; avoid harsh chemicals and ultrasonic cleaners if internal fractures are severe
Interesting Facts
Most diamonds pulled from the earth look like this before master cutters transform them into brilliant sparklers; rough diamonds often feature natural triangular growth depressions called trigons
