Overall Assessment
An interesting, translucent natural rough diamond crystal displaying genuine geological formation features, highly suitable for mineral collectors or custom organic jewelry design.
Cut Quality
Not applicable (Rough, uncut crystal)
Brilliance
Low to moderate due to rough, unpolished nature
Fire
Limited visibility due to unfaceted surface and natural crystal skin
Scintillation
Minimal, as facets are required to return light effectively
Proportions
Natural rough proportions, heavily dependent on subsequent cutting choices
Symmetry
Natural asymmetrical crystal growth form
Polish
Natural unpolished crystal faces (trigons potentially present)
Fluorescence
Indeterminate from visual assessment alone
Inclusions
Natural internal fracture planes, mineral inclusions, and internal graining
Blemishes
Natural growth lines, etch channels, and rough skin on surface
Origin
Likely alluvial or primary pipe deposit origin (e.g., South Africa, Canada, or Australia)
Treatment Detection
No signs of artificial treatments; completely natural as-mined condition
Estimated Value
Varies widely based on cutting potential, roughly $100 - $300 USD as a raw specimen
Certification Estimate
GIA would issue a Rough Diamond Certificate if submitted prior to cutting
Investment Potential
Low as jewelry stone in rough form, moderate as a unique collector mineral specimen
Similar Diamonds
Uncut run-of-mine gem-quality diamond crystals of similar size and clarity
Setting Suggestions
Best preserved as a raw mineral specimen in a custom organic wire-wrap or protective bezel setting
Care & Maintenance
Store separately from harder gems to avoid scratching other pieces; clean gently with warm soapy water and a soft brush
Interesting Facts
Rough diamonds retain their natural octahedral or distorted crystal shapes formed deep within the Earth's mantle over billions of years
