Not applicable (Rough, unpolished crystal) Cut
Carat
Not applicable (Rough mineral specimen, weight estimated in grams rather than carats)
Color
Not applicable (Mineral exhibits deep blue fluorescence under light/UV exposure)
Clarity
Included / Heavily fractured rough specimen
Shape
Rough crystal shard / uncut mineral specimen
Overall Assessment
The specimen shown is not a diamond, but rather a naturally fluorescent rough mineral crystal displaying vibrant blue luminescence. Further gemological testing is recommended to definitively identify the exact mineral species.
Cut Quality
Not applicable (Rough, unpolished crystal)
Brilliance
Not applicable
Fire
Not applicable
Scintillation
Not applicable
Proportions
Not applicable
Symmetry
Not applicable (Natural, irregular crystal formation)
Polish
Unpolished natural rough surface
Fluorescence
Very Strong Blue
Inclusions
Heavy internal fracturing, cleavage planes, and mineral inclusions visible
Blemishes
Natural surface etching, rough edges, and uneven crystal faces
Origin
Natural geological mineral formation
Treatment Detection
No apparent artificial treatments; luminescence is a natural property of the mineral
Estimated Value
Nominal value as a mineral specimen / rough crystal piece
Certification Estimate
Gemological testing laboratory (such as GIA or EGL) for mineral species identification
Investment Potential
Low (Collector mineral specimen rather than a gemstone investment)
Similar Diamonds
None (This is a non-diamond mineral specimen)
Setting Suggestions
Wire-wrapped rough mineral jewelry or display specimen mount
Care & Maintenance
Handle with care to avoid breakage along natural cleavage planes; keep away from harsh chemicals and ultrasonic cleaners
Interesting Facts
Many minerals such as fluorite exhibit strong fluorescence when exposed to ultraviolet light due to trace impurities within the crystal lattice
