Rough diamond crystals in matrix (Natural)
Rough diamond crystals in matrix (Natural) · Uncut natural crystal forms (primarily octahedral and dodecahedral)
Not applicable (uncut rough material) Cut

Carat
Various microscopic and small crystals, total aggregate weight difficult to estimate without extraction
Color
Grayish/brownish industrial grade rough (Boart/Industrial)
Clarity
Included (I2-I3 or lower equivalent for rough)
Shape
Uncut natural crystal forms (primarily octahedral and dodecahedral)
Overall Assessment
A fascinating cluster of natural rough diamond crystals embedded within their host rock matrix, primarily suited for mineral collections, educational display, or industrial use rather than gemstone jewelry.
Cut Quality
Not applicable (uncut rough material)
Brilliance
Low to moderate due to rough surfaces and inclusion density
Fire
Minimal visible fire in current rough state
Scintillation
Limited, dependent on natural crystal facets
Proportions
Natural crystal habit, varying depths and angles
Symmetry
Natural crystal symmetry (cubic system)
Polish
Natural unpolished crystal faces (terrace, trigons possible)
Fluorescence
Cannot be determined without UV testing
Inclusions
Heavy internal cloudiness, feathering, and mineral inclusions typical of rough industrial diamonds
Blemishes
Natural surface pitting, trigons, and rough skin
Origin
Likely primary kimberlite or secondary alluvial deposit
Treatment Detection
No signs of enhancement; entirely untreated natural rough
Estimated Value
Industrial/abrasive value, nominal per carat
Certification Estimate
Industrial assessment rather than formal grading lab (e.g., GIA rough evaluation)
Investment Potential
Value lies in specimen/educational worth rather than financial investment
Similar Diamonds
Standard run-of-mine industrial rough and kimberlite ore samples
Setting Suggestions
Raw mineral specimen display, wire-wrapped raw crystal jewelry
Care & Maintenance
Keep embedded in matrix or handle carefully as a mineral specimen; avoid harsh chemicals
