Brilliance
None (non-reflective opaque surface).
Fire
None
Scintillation
None

Triangular blade with side notches and a flat base.
Symmetry
Poor/Asymmetrical (side-notched form).

Fluorescence
None
Inclusions
Natural mineral banding and matrix typical of sedimentary silica.
Blemishes
Edge wear and impact fractures consistent with use or age.
Origin
Likely North American indigenous lithic origin.
Treatment Detection
Possible heat treatment (historic) to improve knapping quality.
Estimated Value
$5 - $50 (based on condition and archaeological provenance).
Certification Estimate
N/A - Would require archaeological authentication rather than gemological grading.
Investment Potential
Low as a gemstone; moderate as a historical collectible.
Similar Diamonds
None; this has no crystalline diamond structure.
Setting Suggestions
Shadow box display or a wire-wrapped pendant.
