Not applicable (uncut raw specimen). Cut

Carat
Unable to determine accurately from image alone, estimated over 5 carats based on rough dimensions.
Color
Deep blue body color with strong blue UV reactive fluorescence.
Clarity
Included / opaque with heavy natural mineral fractures and surface inclusions.
Shape
Rough uncut crystal / irregular fragment, non-standard shape.
Overall Assessment
This specimen is visually identified as a non-diamond rough mineral with intense blue fluorescence, unsuitable for traditional jewelry settings without extensive custom lapidary work.
Cut Quality
Not applicable (uncut raw specimen).
Brilliance
Minimal, due to lack of standard facet geometry and high opacity.
Fire
Absent, due to lack of optical dispersion and diamond crystal structure.
Scintillation
Poor / non-existent as the material is rough and largely opaque.
Proportions
Non-standard; raw crystal form with undefined table, depth, and angles.
Symmetry
Irregular, as typical for rough untreated mineral specimens.
Polish
Raw, unpolished matrix with natural fracture planes.
Fluorescence
Very Strong Blue fluorescence under ultraviolet excitation.
Inclusions
Heavy internal clouding, fractures, feathers, and trapped mineral impurities.
Blemishes
Rough surface pitting, natural abrasions, and structural fissures.
Origin
Natural mineral rough or synthetic industrial material, inconclusive from photo.
Treatment Detection
Possible synthetic or coated material indicated by unnatural deep blue luminescence.
Estimated Value
Minimal monetary value as a gem-grade stone; valued primarily as a mineral specimen.
Certification Estimate
Not eligible for diamond certification by major gemological institutes like GIA or AGS.
Investment Potential
Low investment potential as a gemstone; strictly collector or decorative mineral status.
Similar Diamonds
None, as this specimen does not share diamond characteristics.
Setting Suggestions
Wire-wrapped organic setting or custom bezel designed to hold irregular rough stones.
Care & Maintenance
Store carefully away from hard surfaces to prevent chipping along natural fracture planes; clean gently with mild soap and water.
Interesting Facts
Stunning strong blue fluorescence under UV light is often caused by trace activator elements or synthetic doping.
