Rough natural diamond crystal (or potentially quartz/quartzite based on surface texture, assuming diamond context)
Rough natural diamond crystal (or potentially quartz/quartzite based on surface texture, assuming diamond context) · Rough crystal / Irregular unpolished shape
Uncut / Rough (Not applicable for standard cut grades) Cut
Carat
Estimated 3.0 to 5.0 carats based on visual size
Color
Off-white / Yellowish brown (Fancy Light Brownish Yellow tint)
Clarity
I3 (Heavy inclusions, heavily fractured and included)
Shape
Rough crystal / Irregular unpolished shape
Overall Assessment
This is an unpolished, heavily included rough natural diamond crystal of industrial or low gem quality, displaying natural weathering and internal characteristics typical of alluvial deposits
Cut Quality
Uncut / Rough (Not applicable for standard cut grades)
Brilliance
Poor due to lack of facets and opaque/translucent rough nature
Fire
Negligible due to lack of proper diamond faceting and heavy inclusions
Scintillation
None present on unpolished rough surface
Proportions
Natural uncut proportions, irregular depth and table
Symmetry
Asymmetrical rough formation
Polish
Unpolished natural crystal surface / weathered skin
Fluorescence
Indeterminate from visual inspection
Inclusions
Multiple internal feathers, clouds, dark carbon spots, and fractures visible
Blemishes
Natural surface pitting, trigons or etching marks, rough skin
Origin
Alluvial secondary deposit (rough weathered appearance suggests river or stream bed origin)
Treatment Detection
None detected; appears completely untreated and in its natural rough state
Estimated Value
Nominal value as a mineral specimen or industrial grade stone (low market value due to heavy inclusion and lack of gem-cutting potential)
Certification Estimate
GIA or similar major labs would grade this as industrial or low-gem quality rough natural diamond
Investment Potential
Low investment potential for jewelry use; primarily of interest as a raw mineral specimen or educational piece
Similar Diamonds
Industrial grade rough diamonds, uncut alluvial diamond specimens
Setting Suggestions
Wire-wrapped or organic bezel setting to showcase its raw, uncut mineral beauty
Care & Maintenance
Standard care for raw minerals; avoid harsh chemicals and impact that could worsen internal fractures
Interesting Facts
Most diamonds are recovered as rough crystals like this before being meticulously cut and polished to maximize brilliance
