Shape
Irregular / Crystalline aggregate
Overall Assessment
The specimen is a raw mineral druse or crystal pocket in rock, not a cut or uncut diamond.
Cut Quality
Uncut / Raw mineral formation
Brilliance
Low due to lack of faceting and opaque nature
Fire
None
Scintillation
Minimal to none
Proportions
Not applicable
Symmetry
Asymmetrical raw formation
Polish
Unpolished natural matrix
Fluorescence
Unknown without UV testing
Inclusions
Heavy internal fracturing and matrix inclusions
Blemishes
Natural surface etching and rough texture
Origin
Natural geological formation within host rock
Treatment Detection
No treatments detected; natural state
Estimated Value
Minimal specimen value as a raw rock sample
Certification Estimate
Gemological laboratories would identify this as quartz or calcite rather than a diamond.
Investment Potential
Low; valuable only as a geological or mineral specimen
Similar Diamonds
None (this is not a diamond)
Setting Suggestions
Not suitable for standard jewelry settings without significant cutting and polishing
Care & Maintenance
Standard mineral specimen care, keep away from harsh acids if calcite
Interesting Facts
Shows a vug or cavity filled with secondary mineral crystals within the host rock
