Indeterminate (Similarity to rough Quartz or Glass)
Indeterminate (Similarity to rough Quartz or Glass) · Rough / Uncut (Natural asymmetric form)
N/A (Unfaceted) Cut
Carat
Estimated 15-25 carats based on finger scale
Color
Colorless (Near D-E equivalent)
Clarity
Translucent to Transparent with visible internal fractures
Shape
Rough / Uncut (Natural asymmetric form)
Overall Assessment
This specimen appears to be a piece of rough quartz or glass cullet rather than a diamond, evidenced by its fracture patterns and lack of adamantine luster.
Cut Quality
N/A (Unfaceted)
Brilliance
Low (Lacks facets to reflect light)
Fire
Low (Visible only at internal fracture interfaces)
Scintillation
Minimal
Proportions
Asymmetrical rough pebble shape
Symmetry
N/A
Polish
N/A (Rough surface)
Fluorescence
Unknown without UV testing
Inclusions
Conchoidal fractures and internal cleavage planes visible
Blemishes
Surface pitting and earthy residue
Origin
Alluvial deposit (likely non-diamond based on fracture)
Treatment Detection
None apparent; appearance is characteristic of raw silicate
Estimated Value
$10 - $50 (if quartz/glass); potentially higher if diamond
Certification Estimate
GIA Rough Diamond Report (if confirmed diamond)
Investment Potential
Low (Speculative unless mineral identity is confirmed)
Similar Diamonds
Uncut Herkimer diamonds or rough clear quartz
Setting Suggestions
Wire wrap or custom cage setting for organic look
Care & Maintenance
Avoid impact due to prominent cleavage/fracture planes
Interesting Facts
The scalloped conchoidal fractures are highly characteristic of glass or quartz rather than diamond's octahedron cleavage.
