Carat
Not applicable; gemstone specimen rather than a cut diamond
Color
Milky white with brownish-grey matrix staining
Clarity
Heavily included, opaque to translucent areas with extensive fracturing
Shape
Rough, uncut, irregular nodule/pebble form
Overall Assessment
This specimen is a rough, unworked silicate mineral (likely quartz or chalcedony) embedded in a matrix, possessing no gemological characteristics of a diamond.
Cut Quality
Uncut / Natural raw state
Brilliance
Very low due to lack of facets and opaque/translucent nature
Fire
None
Scintillation
None
Proportions
Not applicable to raw mineral formations
Symmetry
Asymmetrical raw mineral formation
Polish
Unpolished, rough natural surface with some weathering
Fluorescence
Unknown without UV testing
Inclusions
Heavy internal fracturing, crystal impurities, and foreign mineral staining
Blemishes
Natural surface pits, fractures, and adhering host rock matrix
Origin
Alluvial deposit or surface weathering environment
Treatment Detection
None detected; appears entirely natural and untreated
Estimated Value
Minimal monetary value as a decorative mineral specimen (few dollars)
Certification Estimate
Not gradable by diamond grading laboratories (GIA/AGS); would require geological analysis
Investment Potential
None; purely of educational or specimen interest
Similar Diamonds
None, as this is a rough quartz/silicate rock rather than diamond
Setting Suggestions
Wire-wrapping or rustic bezel setting if used in organic jewelry
Care & Maintenance
Standard cleaning with warm soapy water and a soft brush
Interesting Facts
Often mistaken by novices for rough diamond due to its translucent quartz appearance and crystalline texture
