Indeterminate (Likely non-diamond silicate mineral like Quartz or a rough glass fragment)
Indeterminate (Likely non-diamond silicate mineral like Quartz or a rough glass fragment) · Rough / Uncut (Irregular shard)
Not applicable (Raw/Rough material) Cut
Carat
Estimated 0.5 - 1.5 carats based on size relative to fingers
Color
Low transparency; appears grayish-brown or tinted
Clarity
Included (I3 equivalent) - Heavily fractured and opaque areas
Shape
Rough / Uncut (Irregular shard)
Overall Assessment
This specimen lacks the characteristic crystal habit (octahedron) and refractive properties typically seen in rough diamonds. It appears to be a shard of a common silicate mineral or weathered glass.
Cut Quality
Not applicable (Raw/Rough material)
Brilliance
Poor; low light return due to rough surface and internal fracturing
Fire
None detected; specimen does not show spectral dispersion
Scintillation
Low; lacks the pattern of light and dark associated with structured crystals
Proportions
Not measurable (Non-faceted)
Symmetry
None (Asymmetrical rough fragment)
Polish
Natural rough surface; lacks polished facets
Fluorescence
Indeterminate without UV light source
Inclusions
Heavy internal fracturing, clouding, and possible carbon or mineral crystals
Blemishes
Rough, jagged surface edges and significant abrasions
Origin
Alluvial source or surface find (non-lab setting)
Treatment Detection
Naturally occurring rough; no evidence of enhancement
Estimated Value
$0 - $10 (Specimen value/rough mineral cost)
Certification Estimate
Unlikely to be graded by GIA/IGI unless significant value is proven; likely identified as a common mineral
Investment Potential
None; lacks the quality, size, or structure for gem-quality investment
Similar Diamonds
Low-grade industrial bort or rough quartz crystals
Setting Suggestions
Wire wrapping for a raw specimen look transition; not suitable for traditional prong settings
Care & Maintenance
Store separately to avoid scratching softer materials, though specimen itself appears brittle
Interesting Facts
Many 'found' stones are often Quartz or Topaz, which can mimic the appearance of rough diamond to the untrained eye
