None (non-reflective, opaque matrix)
Fire
None
Scintillation
None
Proportions
Not applicable
Symmetry
Asymmetrical, naturally tumbled
Polish
Matte, weathered rough surface
Fluorescence
Not applicable
Inclusions
Abundant mineral grains, quartz microcrystals, and matrix material
Blemishes
Natural pitting, surface weathering, and micro-fractures
Origin
Alluvial deposit, river rock, or weathered terrestrial outcrop
Treatment Detection
None (completely untreated natural geological specimen)
Estimated Value
Nominal value as a geological specimen or decorative stone
Certification Estimate
Not applicable for gemological grading; better suited for geological identification (e.g., standard petrographic analysis)
Investment Potential
None as a gemstone
Similar Diamonds
None (no relation to diamond)
Setting Suggestions
Not suitable for jewelry setting due to softness and opacity
Care & Maintenance
Standard cleaning with water and mild soap if used as a decorative display piece
Interesting Facts
Shows typical surface weathering and granular texture characteristic of silicate rocks rather than single-crystal gemstones
