Not applicable (Rough stone) Cut
Carat
Estimated 2.0 to 3.5 carats
Color
Near-colorless to light brown tint (G-J range)
Clarity
I3 (Included with prominent internal fractures and feather inclusions)
Shape
Rough / Uncut irregular fragment
Overall Assessment
This is an untreated, heavily fractured natural diamond rough fragment of lower clarity, primarily suited for mineral collections or industrial applications rather than high-end jewelry use.
Cut Quality
Not applicable (Rough stone)
Brilliance
Low due to heavy internal fracturing and lack of standard facet alignment
Fire
Minimal dispersion visible through raw fracture windows
Scintillation
Poor, interrupted by internal fracturing and opaque inclusion zones
Proportions
Irregular raw crystal form without standard table or pavilion proportions
Symmetry
Asymmetrical due to rough, unpolished state
Polish
Unpolished natural crystal surfaces and fracture planes
Fluorescence
Indeterminate from visual inspection
Inclusions
Heavy internal feather fractures, cleavages, and dark mineral spots
Blemishes
Natural surface etch channels, trigons, and rough fracture edges
Origin
Alluvial or primary kimberlite rough diamond deposit
Treatment Detection
No signs of artificial treatment; appears entirely natural and untreated
Estimated Value
Nominal value as a mineral specimen or low-grade industrial diamond
Certification Estimate
GIA or IGI would classify this as an industrial or low-gem quality rough diamond
Investment Potential
Low investment potential for resale as a gemstone; primarily of interest to mineral collectors
Similar Diamonds
Industrial-grade rough diamond fragments and natural uncut crystal specimens
Setting Suggestions
Best preserved as a raw mineral specimen in a custom wire-wrap or bezel protective setting if used in organic jewelry
Care & Maintenance
Handle with care to prevent further fracturing along existing cleavage planes; clean gently with warm soapy water and a soft brush
Interesting Facts
Rough diamonds display natural crystal growth marks such as triangular etchings called trigons on their faces before being cut and polished
