Symmetry
N/A (Rough form)
Polish
Natural surface textures (Trigons and growth lines visible)
Fluorescence
None visible under current lighting
Inclusions
Few visible dark carbon spots (inclusion) and internal stress fractures
Blemishes
Surface percussion marks and natural growth step ridges

Care & Maintenance
Clean with warm soapy water and a soft brush; avoid sharp impacts on cleavage planes
Interesting Facts
The surface displays distinct growth lines known as 'striations', which are a definitive hallmark of natural isometric crystal growth.
