Brilliance
Low to moderate due to rough, unpolished surface
Fire
Minimal visible fire on raw surfaces
Scintillation
Poor due to lack of faceted geometry
Proportions
N/A for rough stone
Symmetry
Natural asymmetrical crystal form
Polish
Raw crystal surfaces with natural growth lines (trigons/striations)
Fluorescence
Cannot be determined without UV light testing (typically Medium Blue in natural rough)
Inclusions
Internal feather fractures, cloudiness, and mineral inclusions visible
Blemishes
Natural surface pitting, rough skin, and irregular edges
Origin
