Not a diamond; this is a rough blue gemstone, likely sapphire or a similar mineral specimen, showing strong blue coloration.
Not a diamond; this is a rough blue gemstone, likely sapphire or a similar mineral specimen, showing strong blue coloration. · Rough crystal / Uncut elongated crystal formation
Not applicable (Rough, uncut stone) Cut
Carat
Estimated around 3 to 5 carats based on visual dimensions (requires precise scale measurement)
Color
Deep Fancy Blue
Clarity
Included (Contains visible internal fractures and structural inclusions typical of rough material)
Shape
Rough crystal / Uncut elongated crystal formation
Overall Assessment
An interesting, vibrant blue rough crystal specimen that requires formal gemological testing to confirm exact species, identity, and commercial grade
Cut Quality
Not applicable (Rough, uncut stone)
Brilliance
Low in current rough state, would require proper faceting to exhibit internal and external brilliance
Fire
Minimal dispersion visible in current opaque/rough form
Scintillation
Absent in rough, uncut state
Proportions
Not applicable for rough uncut mineral specimens
Symmetry
Natural asymmetrical rough crystal formation
Polish
Raw, unpolished crystalline surface with natural growth lines and texture
Fluorescence
Cannot be definitively determined without UV light testing, but displays strong vibrant color under ambient light
Inclusions
Internal feather fractures, crystal growth zones, and possible mineral inclusions typical of untreated rough stones
Blemishes
Natural surface pitting, rough patches, and uneven texture due to unpolished state
Origin
Natural rough mineral specimen, likely alluvial or pegmatitic origin depending on exact stone type
Treatment Detection
Requires professional laboratory testing (spectroscopy/microscopy) to determine if heat treated or untreated
Estimated Value
Varies significantly depending on precise mineral identification (e.g., rough sapphire vs. colored glass or quartz), ranging from modest mineral specimen value to hundreds of dollars
Certification Estimate
GIA or Gubelin (if verified as a rare colored gemstone)
Investment Potential
Low to moderate as a raw mineral specimen; highly dependent on professional gemstone authentication and cutting potential
Similar Diamonds
None, as this is visually not a diamond
Setting Suggestions
Custom wire-wrap setting or protective bezel setting designed specifically for raw, organic mineral specimens
Care & Maintenance
Store separately in a soft pouch to prevent scratching; clean gently with mild soapy water and a soft brush
Interesting Facts
Rough gemstones in their natural crystalline state showcase the raw geological processes of the Earth before human shaping
