Natural crystal habit, non-standard geometric proportions
Symmetry
Natural crystallographic symmetry showing octahedral faces
Polish
Natural crystal face texture with typical trigons and growth lines
Fluorescence
Likely Faint to Medium Blue (common in natural rough crystals)
Inclusions
Internal clouds, feathers, and dark mineral inclusions visible within the crystal matrix
Blemishes
