Rough natural crystal specimen (showing conchoidal fracture lines and striations characteristic of crystalline quartz or rough diamond, though visually strongly indicative of untreated natural rough mineral crystal)
Rough natural crystal specimen (showing conchoidal fracture lines and striations characteristic of crystalline quartz or rough diamond, though visually strongly indicative of untreated natural rough mineral crystal) · Rough uncut crystal / Untreated raw form
Not applicable for rough crystal specimens Cut
Carat
Estimated 4.5 to 6.5 carats based on visual proportions and mineral density
Color
Colorless / Near-colorless with slight natural surface weathering
Clarity
Included / Industrial to collector grade (visible natural inclusions, growth lines, and fracture planes)
Shape
Rough uncut crystal / Untreated raw form
Overall Assessment
An interesting and tactile raw mineral crystal specimen exhibiting characteristic natural growth patterns, surface striations, and fracture faces ideal for mineral collectors and educational study
Cut Quality
Not applicable for rough crystal specimens
Brilliance
Vitreous to adamantine reflection off natural cleavage and fracture planes
Fire
Minimal dispersion observed due to lack of precision cut facets
Scintillation
Limited flash effect restricted to raw specular reflection planes
Proportions
Irregular raw crystal proportions without standard facet angles
Symmetry
Asymmetrical raw crystal formation
Polish
Raw, unpolished natural crystal surfaces with growth striations
Fluorescence
Indeterminate from visual assessment alone
Inclusions
Internal feather fractures, cloudiness, and stress lines typical of raw mineral specimens
Blemishes
Natural surface etching, trigons or parallel growth striations, and minor matrix staining
Origin
Natural primary alluvial or kimberlite/pegmatite deposit depending on exact host rock matrix
Treatment Detection
No evidence of artificial treatments; completely natural as-mined state
Estimated Value
Specimen collector valuation ranging from $50 to $200 depending on exact mineral verification
Certification Estimate
Basic gemological report (GIA Identification Report or similar for rough stones confirming natural origin)
Investment Potential
Valued primarily as a mineral specimen or educational display piece rather than a liquid investment diamond
Similar Diamonds
Other natural unpolished octahedral or irregular rough diamond and mineral crystal specimens
Setting Suggestions
Wire-wrapped pendant setting or custom organic prong setting to preserve raw crystal integrity
Care & Maintenance
Store separately in a soft pouch to prevent scratching other stones; clean gently with warm soapy water and a soft brush
Interesting Facts
Rough crystals display natural growth features like striations and conchoidal fracture lines that are completely removed during the traditional diamond cutting process
