Natural rough crystal fragment, possibly quartz or low-grade industrial diamond, but visually indeterminate raw mineral specimen
Natural rough crystal fragment, possibly quartz or low-grade industrial diamond, but visually indeterminate raw mineral specimen · Rough uncut crystal shard / Irregular
Uncut / Rough (Not applicable for standard cut grades) Cut
Carat
Estimated 2.0 to 4.0 carats based on relative finger size comparison
Color
Near colorless to pale yellowish tint (H-J equivalent)
Clarity
Included (I2-I3 equivalent due to numerous internal fractures, inclusions, and surface defects)
Shape
Rough uncut crystal shard / Irregular
Overall Assessment
This specimen appears to be a raw, unworked mineral crystal fragment rather than a gem-quality polished diamond. Further testing (such as thermal conductivity or Raman spectroscopy) is required to definitively confirm the mineral species.
Cut Quality
Uncut / Rough (Not applicable for standard cut grades)
Brilliance
Very low due to lack of standard facet geometry and raw surface polish
Fire
Minimal to none in current unpolished rough state
Scintillation
Absent due to lack of faceting
Proportions
Non-standard rough geometry
Symmetry
Asymmetrical rough crystal
Polish
Raw crystal faces (Unpolished)
Fluorescence
Indeterminate without UV testing
Inclusions
Heavy internal feather fractures, pinpoints, and dark mineral inclusions
Blemishes
Natural surface etchings, striations, and surface abrasions
Origin
Natural geological origin, alluvial or primary deposit
Treatment Detection
No obvious signs of human treatment; appears untreated raw mineral
Estimated Value
Nominal specimen value ($10 - $50 USD) depending on exact mineral identity
Certification Estimate
Industrial or uncertified mineral specimen; major labs like GIA would not grade rough utility pieces without cutting
Investment Potential
Poor investment potential as a gemstone; strictly a mineral specimen
Similar Diamonds
Industrial grade boart or low-grade unworked natural diamond crystals
Setting Suggestions
Wire-wrapped or custom raw crystal bezel setting if polished into a display piece
Care & Maintenance
Store carefully to avoid chipping along natural cleavage planes
Interesting Facts
Rough crystals display natural growth lines and striations which are completely removed during standard brilliant faceting
