Natural
Natural · Rough / Uncut Crystal
Not Applicable (Rough Crystal) Cut
Carat
Estimated 3.50 to 4.50 carats
Color
Near Colorless to Faint Yellow (approx. G-I range)
Clarity
Included (I1 to I2 range due to central dark inclusion and structural fractures)
Shape
Rough / Uncut Crystal
Overall Assessment
An interesting, substantial natural rough diamond crystal displaying classic geological growth features and a significant central inclusion. Its ultimate value and beauty depend heavily on a master cutter's skill in planning and sawing to maximize weight while removing or minimizing internal flaws.
Cut Quality
Not Applicable (Rough Crystal)
Brilliance
Low in current rough state; highly dependent on future cutting and polishing
Fire
Minimal dispersion visible through rough, uneven surface faces
Scintillation
Absent in rough form; will develop upon faceting
Proportions
Natural uncut proportions
Symmetry
Natural crystal symmetry (irregular, elongated octahedral/dodecahedral habit)
Polish
Natural crystal face texture (trigons and striations visible)
Fluorescence
Cannot be determined visually without UV testing (likely None to Faint)
Inclusions
Prominent central dark/black inclusion, internal feather fractures, and cloud formations
Blemishes
Natural surface etch channels, trigons, and rough skin
Origin
Likely alluvial or primary kimberlite pipe deposit (African or Canadian origin typical for such rough)
Treatment Detection
No signs of artificial treatments; completely natural untreated rough
Estimated Value
Variable based on cutter's yield potential, roughly $1,500 to $3,500 USD for rough mineral specimen/industrial-to-commercial grade
Certification Estimate
GIA or similar major laboratory would issue a rough diamond report or grade the finished polished stone significantly lower due to heavy inclusions
Investment Potential
Moderate as a raw mineral specimen, lower for polished investment due to clarity constraints
Similar Diamonds
Comparable industrial-grade or commercial-grade uncut rough diamonds with prominent internal flaws
Setting Suggestions
Recommended to be custom cut into an antique or cushion shape to minimize weight loss around the central dark inclusion, or kept as a raw mineral specimen in an organic designer setting
Care & Maintenance
Store in a fabric-lined box away from harder gems; clean gently with warm soapy water and a soft brush
Interesting Facts
Displays natural growth lines (striations) and surface features called trigons, which are triangular etch marks formed deep within the earth's mantle
