Natural rough industrial/gem-quality diamond (or potentially a heavily included diamond crystal/quartzite specimen, assuming diamond for this evaluation)
Natural rough industrial/gem-quality diamond (or potentially a heavily included diamond crystal/quartzite specimen, assuming diamond for this evaluation) · Rough, unpolished pebble/crystal form (Rounded / Irregular)
Not applicable (Rough, unpolished stone) Cut
Carat
Estimated 2.0 to 3.5 carats based on visual scale against fingers
Color
Fancy Dark Brownish-Yellow / Industrial grade tint
Clarity
I3 (Included / Heavily fractured and included)
Shape
Rough, unpolished pebble/crystal form (Rounded / Irregular)
Overall Assessment
An interesting, heavily included natural rough diamond crystal showing significant surface texture and internal fractures, best suited for mineral collections rather than jewelry cutting.
Cut Quality
Not applicable (Rough, unpolished stone)
Brilliance
Minimal to none due to rough exterior and heavy internal inclusions
Fire
Extremely low to none in its current rough state
Scintillation
Absent due to lack of faceted surfaces
Proportions
N/A for rough crystal
Symmetry
Natural irregular crystal symmetry
Polish
Raw, unpolished natural surface with frosted/etched features
Fluorescence
Indeterminate from visual assessment (typically inert to faint in lower quality rough)
Inclusions
Heavy internal fracturing, cleavage planes, mineral inclusions, dark carbon spots
Blemishes
Natural surface pitting, trigons or etching marks, surface graining
Origin
Alluvial deposit (river bed or secondary source due to rounded pebble shape)
Treatment Detection
No obvious signs of artificial enhancement; appears completely untreated and natural
Estimated Value
Nominal value as a mineral specimen or industrial abrasive ($20 - $100 depending on actual composition)
Certification Estimate
Grading labs like GIA or EGL would classify this as rough industrial or low-tier near-gem quality
Investment Potential
Very low; primarily of interest to mineral collectors rather than gemstone investors
Similar Diamonds
Industrial grade boart or low-quality alluvial rough diamond crystals
Setting Suggestions
Best kept as a raw mineral specimen in a wire-wrap or bezel setting if used in organic jewelry
Care & Maintenance
Store separately to prevent scratching other stones; avoid harsh chemical cleaners due to internal fractures
Interesting Facts
Most natural diamonds mined globally are of industrial quality rather than gem quality, often used for cutting tools and abrasives
