Scintillation

None in current rough state

Proportions

Natural rough proportions, requires sawing and planning for optimal yield

Symmetry

Natural crystal symmetry, distorted growth

Polish

Natural crystal faces (trigons and striations visible)

Fluorescence

Cannot be determined visually without UV light (Likely None to Faint)
