Not a diamond; rough crystalline gemstone material, possibly garnet or tourmaline based on color and texture
Not a diamond; rough crystalline gemstone material, possibly garnet or tourmaline based on color and texture · Uncut rough crystal fragment
Not applicable (rough, uncut specimen) Cut
Carat
Undetermined due to incomplete visible specimen and lack of scale
Color
Deep dark red / burgundy
Clarity
Included / opaque rough stone
Shape
Uncut rough crystal fragment
Overall Assessment
The provided image displays a raw, dark red crystalline mineral fragment rather than a faceted diamond, requiring professional gemological testing to determine its exact mineral species.
Cut Quality
Not applicable (rough, uncut specimen)
Brilliance
Low to none due to lack of faceting and opaque/rough nature
Fire
None
Scintillation
None
Proportions
Not applicable
Symmetry
Natural crystal asymmetry
Polish
Unpolished natural surface
Fluorescence
Unknown without UV testing
Inclusions
Natural mineral inclusions and internal fractures typical of rough gemstones
Blemishes
Natural surface etching and rough texture
Origin
Natural geological formation, specific origin unknown
Treatment Detection
No obvious signs of human treatment, appears entirely natural
Estimated Value
Nominal value as mineral specimen, dependent on exact mineral species
Certification Estimate
Requires specialized gemological lab testing (GIA, Gubelin, etc.) for exact species identification
Investment Potential
Collector mineral specimen value rather than investment-grade gemstone
Similar Diamonds
None, as this is not a diamond
Setting Suggestions
Wire-wrapped or organic bezel setting suitable for rough mineral specimens
Care & Maintenance
Avoid harsh chemicals, ultrasonic cleaners, and hard impacts
Interesting Facts
Rough mineral specimens preserve the natural crystal growth habits formed deep within the earth
