Symmetry
Natural octahedral symmetry with irregular growth patterns
Polish
Natural rough crystal faces with trigons and striations
Fluorescence
Indeterminate from visual assessment alone, likely none to faint

Estimated Value
Varies widely based on raw gem quality, approx. $300 to $800 depending on cutting yield
