Natural rough diamond crystal
Natural rough diamond crystal · Uncut raw octahedral/irregular crystal form
Not applicable (Rough uncut stone) Cut
Carat
Estimated 3.5 to 4.5 carats based on visual proportions and rough dimensions
Color
Estimated near-colorless to faint yellow tint (G-J range)
Clarity
Estimated included/industrial to low clarity due to prominent surface features and internal feathers (I1-I2 equivalent)
Shape
Uncut raw octahedral/irregular crystal form
Overall Assessment
An interesting and substantial natural rough diamond crystal displaying authentic geological features, making it ideal either as a raw collector's specimen or as a candidate for custom cutting
Cut Quality
Not applicable (Rough uncut stone)
Brilliance
Low to moderate vitreous to adamantine luster typical of rough crystalline material
Fire
Minimal dispersion due to rough, unpolished surface refracting light diffusely
Scintillation
Poor light return and sparkle pattern resulting from unfaceted surfaces
Proportions
Irregular rough dimensions; lacks traditional faceted pavilion, crown, and table percentages
Symmetry
Natural crystal asymmetry with distorted growth faces and trigons
Polish
Natural unpolished crystal faces (terrace lines, striations, and resorption features present)
Fluorescence
Cannot be determined without UV testing (Likely none to faint blue)
Inclusions
Prominent internal feathers, cleavage planes, carbon spots, and cloud clusters visible
Blemishes
Natural growth surface features, pitted areas, triangular indentations (trigons), and adhering mineral residue
Origin
Likely alluvial or primary kimberlite deposit origin (African or Canadian source)
Treatment Detection
No signs of enhancement or artificial treatment; completely natural untreated rough
Estimated Value
Varies by precise weight and clarity, roughly $500 to $1,500 for specimen or cutting rough value
Certification Estimate
GIA would issue a Diamond Rough Report detailing weight, measurements, and natural origin without standard color/clarity grading
Investment Potential
Moderate value as a unique raw mineral specimen; higher potential if expertly cut and faceted into a polished gem
Similar Diamonds
Comparable raw uncut diamond specimens sold for jewelry-making or mineral collections
Setting Suggestions
Best suited for an organic raw-stone bezel setting in yellow or white gold to preserve its natural form
Care & Maintenance
Clean with warm soapy water and a soft brush; avoid harsh ultrasonic cleaners due to internal cleavage planes that could cause fracturing
Interesting Facts
The surface exhibits classic natural growth lines and striations formed deep within the Earth's mantle over millions of years
