Natural (Rough / Uncut)
Natural (Rough / Uncut) · Rough Crystal (Irregular / Fragmented octahedral or macle tendencies)
Not Applicable (Rough, unpolished crystal specimen) Cut
Carat
Estimated 0.50 to 0.80 carats (Visual assessment)
Color
Near-Colorless to Light Brownish Tint (Estimated G-J range)
Clarity
Included (Estimated I1-I2 due to visible internal fracturing and feather structures)
Shape
Rough Crystal (Irregular / Fragmented octahedral or macle tendencies)
Overall Assessment
This is an interesting, natural rough diamond specimen held between fingers. While lacking the optical performance of a polished gem, its raw, uncut character holds a unique appeal for bespoke jewelry designers and mineral collectors. Due to internal fractures, cutting it would require careful planning to maximize yield and clarity.
Cut Quality
Not Applicable (Rough, unpolished crystal specimen)
Brilliance
Low to Moderate due to rough, unpolished state and internal inclusions
Fire
Minimal due to lack of standard facet angles and polished crown/pavilion
Scintillation
Fragmented and irregular flash patterns reflecting off natural crystal faces and cleavage planes
Proportions
Not Applicable (Rough uncut crystal, highly asymmetric naturally occurring form)
Symmetry
Natural Irregular Symmetry
Polish
Natural Rough Surface (Unpolished crystal faces)
Fluorescence
Indeterminate without UV testing (Likely None to Faint)
Inclusions
Internal feathers, cleavage planes, and dark carbon spots visible
Blemishes
Natural trigons or surface pitting typical of rough diamond recovery, along with natural fracture edges
Origin
Likely Alluvial or Primary Kimberlite Pipe Deposit (Africa, Canada, or Russia)
Treatment Detection
No signs of artificial treatment; appears completely untreated and in its natural mined state
Estimated Value
$100 to $400 USD (Highly dependent on final yield if cut, and collector value for raw crystals)
Certification Estimate
GIA or EGL (Rough Diamond Evaluation or Gemological Report specifying raw specimen status)
Investment Potential
Low to Moderate as an investment gem, though high interest in niche raw-diamond jewelry markets
Similar Diamonds
Uncut industrial or jewelry-grade rough diamond octahedrons and fragments sold to bespoke artisan jewelers
Setting Suggestions
Organic bezel setting or raw-stone claw prong setting in yellow gold or platinum to highlight its raw beauty
Care & Maintenance
Clean gently with warm soapy water and a soft brush; avoid harsh ultrasonic cleaners due to existing natural internal fractures and cleavage planes
Interesting Facts
Rough diamonds retain the ancient geological journey they took from Earth's mantle, often preserving natural growth lines called 'trigons' on their faces.
