Overall Assessment
This appears to be a raw mineral specimen rather than a polished gemstone diamond, showing natural cleavage and crystalline growth structures.
Cut Quality
Uncut / Rough (Not applicable)
Brilliance
Low due to lack of faceting and opaque/translucent nature
Fire
Minimal due to rough, unfaceted surface
Scintillation
Poor due to lack of polished reflective facets

Natural crystal habits, no standard proportions
Symmetry
Natural crystal form, irregular
Polish
None (Raw surface texture)
Fluorescence
Cannot be determined visually without UV testing

Heavy internal fracturing, cleavage planes, and mineral impurities
Blemishes
Surface etching, natural rough texture, and growth lines
