Determined to be Non-Diamond (likely an industrial piece, rough mineral, or non-gemstone pebble based on visual characteristics)
Determined to be Non-Diamond (likely an industrial piece, rough mineral, or non-gemstone pebble based on visual characteristics) · Rough / Uncut / Irregular
Poor / Uncut Cut
Carat
Cannot be accurately determined from the image, but appears to be roughly the size of a small pebble (estimated 3-10 carats if it were gemstone material)
Color
Opaque Dark Grey / Metallic Brown
Clarity
Opaque (I3 or below if evaluated as a gemstone, but likely non-gem grade)
Shape
Rough / Uncut / Irregular
Overall Assessment
The object in the image does not possess the optical properties, crystal structure, or transparency of a gemstone-quality diamond. It is an opaque, irregular material that lacks facet structure and brilliance.
Cut Quality
Poor / Uncut
Brilliance
None (Opaque)
Fire
None
Scintillation
Minimal metallic reflection only
Proportions
Irregular
Symmetry
None / Poor
Polish
Rough / Natural texture with some metallic luster
Fluorescence
None visible
Inclusions
Heavy surface reaching fractures, opaque impurities throughout
Blemishes
Extensive surface pitting, abrasions, and fractures
Origin
Likely terrestrial surface find or industrial byproduct
Treatment Detection
No evidence of gemological treatments; appears in a raw or weathered state
Estimated Value
Negligible market value as a gemstone; primarily of interest as a souvenir or industrial specimen
Certification Estimate
Unlikely to be graded by major labs (GIA, IGI) as it lack gem-quality characteristics
Investment Potential
None
Similar Diamonds
Incomparable to standard commercial diamonds; resembles industrial boart or common pebbles
Setting Suggestions
Not suitable for traditional diamond settings; could only be wire-wrapped if kept as a specimen
Care & Maintenance
General cleaning with mild soap and water; avoid pressure given the visible surface fractures
Interesting Facts
Rough stones found in residential areas are often mistaken for raw diamonds but are frequently quartz, industrial slag, or common minerals.
