Low (Sub-adamantine in raw state)
Fire
None (Raw state does not allow for light dispersion)
Scintillation
Minimal to None (Surface reflection only)
Proportions
Asymmetrically shaped raw mineral specimen
Symmetry
Natural geometric crystal habit with visible fractures
Polish
Rough natural surface (Unpolished)
Fluorescence
Inert to Faint (Typically common for Type IIb blue diamonds)
Inclusions
Crystalline fractures, internal veining, and surface-bound matrix minerals
Blemishes
Natural etching, mechanical chips, and host rock (limonite/quartz) attachment
Origin
Likely Cullinan Mine, South Africa (Historically significant source for blue diamonds)
Treatment Detection
None apparent; looks to be a natural specimen in matrix
Estimated Value
$150,000 - $450,000+ (High value due to the rarity of natural blue rough)

Care & Maintenance
Do not use ultrasonic cleaners; keep away from acids; handle with soft tweezers to prevent chipping
Interesting Facts
Blue diamonds contain boron which replaces carbon atoms and allows the crystal to conduct electricity.
