Natural rough crystal (likely quartz or colorless beryl/topaz given the habit, but analyzed as a rough crystalline mineral specimen; diamond rough usually forms octahedrons or rounded dodecahedrons, whereas this elongation suggests quartz or pegmatite mineral)
Natural rough crystal (likely quartz or colorless beryl/topaz given the habit, but analyzed as a rough crystalline mineral specimen; diamond rough usually forms octahedrons or rounded dodecahedrons, whereas this elongation suggests quartz or pegmatite mineral) · Raw/Uncut Elongated Crystal
Not applicable (uncut rough specimen) Cut
Carat
Estimated 3.5 to 5.0 carats (based on rough visual dimensions)
Color
Colorless to very faint brown/yellow tint
Clarity
Included (rough crystal with internal fractures and inclusions)
Shape
Raw/Uncut Elongated Crystal
Overall Assessment
The specimen shown is a raw, elongated crystalline mineral rather than a standard faceted diamond. It displays natural crystal growth features, striations, and internal fractures typical of unworked rough stones. Proper mineralogical testing (such as refractometer or Raman spectroscopy) is recommended to confirm the exact mineral species.
Cut Quality
Not applicable (uncut rough specimen)
Brilliance
Low (due to rough, unpolished state and internal fractures)
Fire
Minimal in current rough state
Scintillation
None in current rough state
Proportions
Elongated prismatic crystal habit
Symmetry
Natural crystal asymmetry
Polish
Raw natural crystal faces and fracture planes
Fluorescence
Cannot be determined without UV testing
Inclusions
Natural mineral inclusions and internal feather fractures visible
Blemishes
Surface etching, natural growth striations, and rough edges
Origin
Natural alluvial or pegmatite deposit
Treatment Detection
No treatments detected; appears completely untreated and natural
Estimated Value
Low commercial value as a mineral specimen, highly dependent on exact mineral identification
Certification Estimate
Gemological laboratory identification report (GIA or local lab) rather than a cut diamond grading report
Investment Potential
Minimal; primarily of interest as a raw mineral specimen rather than an investment-grade gemstone
Similar Diamonds
Comparable to low-grade industrial rough or raw mineral crystal specimens
Setting Suggestions
Wire-wrapped pendant setting or custom organic prong setting to preserve the raw crystal form
Care & Maintenance
Handle with care to prevent chipping along natural cleavage or fracture lines; clean gently with warm soapy water and a soft brush
Interesting Facts
Rough crystals preserve the natural geological history of their formation, displaying growth lines and striations formed deep within the Earth
