Potential Natural Rough Diamond (Uncut) or Quartz/Glass Alternative
Potential Natural Rough Diamond (Uncut) or Quartz/Glass Alternative · Rough / Uncut / Irregular
Not Applicable (Rough Crystal) Cut
Carat
Estimated 2.0 - 4.0 carats based on finger scale
Color
Estimated Cape Series (M-Z Range) or Light Yellowish Tint
Clarity
Visual estimate: I1 to I3 due to visible internal fractures and cloudiness
Shape
Rough / Uncut / Irregular
Overall Assessment
The specimen appears to be a natural mineral rough, possibly a low-grade diamond or more likely a quartz pebble based on the fractured appearance. Professional testing for hardness and thermal conductivity is required to confirm identity.
Cut Quality
Not Applicable (Rough Crystal)
Brilliance
Low (Unfaceted rough does not reflect light structuredly)
Fire
Low to None (Requires faceting for dispersion)
Scintillation
Low; localized surface reflections only
Proportions
Variable; lacks geometric symmetry of faceted stones
Symmetry
Poor (Natural irregular rough state)
Polish
Not Applicable (Natural surface texture)
Fluorescence
Indeterminate without UV light source
Inclusions
Heavy internal fracturing, cleavage planes, and possible mineral inclusions
Blemishes
Surface percussion marks, pitting, and natural trigons if a diamond
Origin
Likely alluvial/riverbed origin given the presence of mud and outdoor context
Treatment Detection
None apparent; appears to be in a raw, post-extraction state
Estimated Value
Varies significantly ($100 - $800) depending on species and internal quality
Certification Estimate
GIA (Rough Diamond Report) if confirmed as diamond
Investment Potential
Low; specimen quality is suitable for collectors rather than high-end jewelry
Similar Diamonds
Uncut yellow-tinted alluvial rough diamonds from Western Australia or South Africa
Setting Suggestions
Custom claw setting for rough stones or faceting by a professional lapidary
Care & Maintenance
Keep clean with warm soapy water; avoid high-pressure steam if fractures are deep
Interesting Facts
Rough diamonds often have a greasy luster and can form octahedral or dodecahedral shapes
