Natural rough crystal / Uncut mineral specimen (likely Quartz, Herkimer Diamond, or low-grade industrial diamond specimen given conchoidal fracture patterns)
Natural rough crystal / Uncut mineral specimen (likely Quartz, Herkimer Diamond, or low-grade industrial diamond specimen given conchoidal fracture patterns) · Uncut natural crystal / Irregular rough fragment
Not applicable (Rough, unpolished mineral specimen) Cut
Carat
Estimated 15-25 carats based on visual size in hand
Color
Near colorless to light brown tint
Clarity
Included / Industrial grade with prominent internal fractures
Shape
Uncut natural crystal / Irregular rough fragment
Overall Assessment
This specimen exhibits the classic raw characteristics of an uncut mineral crystal with natural fracture lines, requiring significant cutting and polishing to transform into a traditional faceted gemstone.
Cut Quality
Not applicable (Rough, unpolished mineral specimen)
Brilliance
Low due to lack of standard faceting and internal fracturing
Fire
Minimal dispersion visible in current rough state
Scintillation
Poor due to lack of optical symmetry and facet alignment
Proportions
Non-standard natural raw crystal proportions
Symmetry
Asymmetrical natural crystal formation
Polish
Raw, natural cleavage and fracture surfaces
Fluorescence
Cannot be determined visually without UV testing
Inclusions
Heavy internal feather fractures, inclusion clouds, and mineral inclusions
Blemishes
Surface chips, natural growth lines, and rough edges
Origin
Natural geological deposit (alluvial or primary host rock)
Treatment Detection
No evidence of artificial treatments; appears entirely natural
Estimated Value
Nominal mineral specimen value ($10 - $50 depending on exact mineral composition)
Certification Estimate
Standard gemological laboratories (GIA, IGI) would classify this as an uncut mineral specimen rather than a graded gem diamond
Investment Potential
Low investment value; valued primarily as a mineral specimen or educational tool
Similar Diamonds
Comparable to industrial-grade rough diamonds or high-clarity quartz crystals
Setting Suggestions
Wire-wrapped pendant setting suitable for raw mineral specimens
Care & Maintenance
Handle with care to prevent further chipping along natural fracture lines; clean gently with warm soapy water
Interesting Facts
The conchoidal fracture patterns visible on the surface are characteristic of brittle crystalline materials
