Natural rough crystal / mineral specimen (appears to be unpolished quartz or rough diamond crystal, featuring natural conchoidal fracture patterns)
Natural rough crystal / mineral specimen (appears to be unpolished quartz or rough diamond crystal, featuring natural conchoidal fracture patterns) · Rough crystal / Irregular uncut form
Not applicable (Rough, unworked specimen) Cut
Carat
Estimated 3.50 to 5.00 carats based on visible scale against fingers
Color
Near colorless to faint brown tint
Clarity
Included (I1-I2 equivalent due to heavy surface fractures and internal imperfections)
Shape
Rough crystal / Irregular uncut form
Overall Assessment
An intriguing raw mineral specimen displaying natural geological formation features, highly educational and visually interesting for mineral collectors, though lacking gem-grade optical properties
Cut Quality
Not applicable (Rough, unworked specimen)
Brilliance
Low to moderate due to rough unpolished surfaces dispersing light irregularly
Fire
Minimal dispersion observed due to lack of precision-cut facets
Scintillation
Poor due to irregular, matte, and fractured surfaces
Proportions
Natural uncut proportions with undulating surface features and stepped growth layers
Symmetry
Asymmetrical natural crystal form
Polish
Natural unpolished surface with vitreous luster on fracture planes
Fluorescence
Unable to determine without UV testing (Likely none to faint blue)
Inclusions
Heavy internal fracturing, cleavage planes, and iron-oxide staining in crevices
Blemishes
Natural surface etching, rough skin, and conchoidal chipping
Origin
Alluvial deposit or primary kimberlite/pegmatite rough extraction
Treatment Detection
No treatments detected; completely natural as-found condition
Estimated Value
$50 - $150 as a raw mineral specimen
Certification Estimate
Gemological institute (GIA or local lab) report for mineral specimen identification
Investment Potential
Low monetary investment potential; valued primarily as a geological curiosity or specimen piece
Similar Diamonds
Comparable to industrial-grade rough diamond crystals or raw quartz specimens
Setting Suggestions
Wire-wrapped pendant setting or custom organic prong setting to showcase its raw crystal beauty
Care & Maintenance
Handle with care to prevent further chipping along natural fracture planes; clean with warm soapy water and a soft brush
Interesting Facts
Displays classic conchoidal fracture patterns typical of hard crystalline minerals formed under immense geological pressure
