Natural rough mineral crystal (likely quartz, beryl, or topaz, not a diamond)
Natural rough mineral crystal (likely quartz, beryl, or topaz, not a diamond) · Uncut raw crystal (elongated prismatic crystal form)
Not Applicable (Uncut rough crystal) Cut

Carat
Estimated 3.5 to 5.0 carats (based on visible size relative to fingertips)
Color
Colorless / Near-colorless with internal iridescent reflection
Clarity
Included / Heavily fractured raw crystal (not applicable on standard diamond clarity scale)
Shape
Uncut raw crystal (elongated prismatic crystal form)
Overall Assessment
An interesting natural rough crystal specimen showcasing growth features and fracture planes, highly educational for mineral study but not a diamond
Cut Quality
Not Applicable (Uncut rough crystal)
Brilliance
Low to moderate, limited by internal fractures and lack of precise facet angles
Fire
Visible dispersion (fire) localized along internal fracture planes producing rainbow patches
Scintillation
Poor, lacking standard faceted play of light due to unstructured raw surfaces
Proportions
Natural elongated crystal habit; proportions defined by crystal axes rather than cut percentages
Symmetry
Natural crystal symmetry showing elongated prismatic growth
Polish
Raw, unpolished natural crystal faces and fracture planes
Fluorescence
Indeterminate from visual inspection alone
Inclusions
Extensive internal feather fractures, cleavages, and localized iridescence (rainbow effect from light interference)
Blemishes
Natural surface etching, rough skin, and minor matrix attachment points
Origin
Alluvial or pegmatitic rough mineral specimen
Treatment Detection
No signs of artificial treatment; represents untreated natural rough material
Estimated Value
Nominal specimen value as a raw mineral piece (low commercial value)
Certification Estimate
Standard gemological laboratories (GIA, GRS) would identify the mineral species rather than issue a diamond grading report
Investment Potential
Low investment potential; primarily of interest to mineral collectors rather than gemstone investors
Similar Diamonds
None, as this is visually identified as a raw quartz or beryl crystal rather than diamond rough
Setting Suggestions
Wire-wrapped pendant setting or custom organic prong setting to preserve the raw crystal form
Care & Maintenance
Handle with care to prevent further propagation of internal fractures; clean gently with warm soapy water and a soft brush
Interesting Facts
Displays internal optical interference colors (iridescence) along healed fracture planes, commonly mistaken for diamond due to vitreous luster
