Natural (Rough / Uncut Diamond Crystal)
Natural (Rough / Uncut Diamond Crystal) · Irregular Rough Crystal / Rounded Native Form
Not Applicable (Rough, uncut stone) Cut
Carat
Estimated 2.50 to 3.50 carats based on visual dimensions
Color
Near-colorless to faint brown tint (Estimated G-J range)
Clarity
Included (I1-I2 equivalent due to prominent internal fractures, feathers, and mineral inclusions)
Shape
Irregular Rough Crystal / Rounded Native Form
Overall Assessment
This is an intriguing natural rough diamond crystal displaying characteristic surface textures and internal stress fractures. While not suitable for traditional brilliant-cut jewelry in its current state without significant sawing and faceting, it possesses strong appeal for collectors of raw minerals and unique custom jewelry pieces.
Cut Quality
Not Applicable (Rough, uncut stone)
Brilliance
Low to moderate due to rough surfaces and internal fracture planes scattering light
Fire
Minimal due to lack of faceted cut and polished windows
Scintillation
Poor, limited to flashes off natural crystal faces and internal cleavage planes
Proportions
Natural uncut crystal form, non-standard proportions
Symmetry
Natural asymmetrical crystal formation
Polish
Natural rough surface textures, growth lines, and trigons
Fluorescence
Inconclusive without UV testing (Likely none to faint blue)
Inclusions
Heavy internal fracturing, cleavage planes, and localized dark mineral inclusions
Blemishes
Natural surface etching, rough skin, and minor surface abrasions
Origin
Alluvial or primary kimberlite/lamproite deposit (Exact geographic origin requires advanced spectroscopy)
Treatment Detection
No signs of artificial enhancement; entirely natural state
Estimated Value
Variable depending on weight and gem yield; rough specimens of this grade typically trade for industrial to lower-tier gem value ($200 - $600 USD)
Certification Estimate
GIA or similar major lab, typically graded as a rough gem-grade diamond crystal
Investment Potential
Primarily valued as a mineral specimen or collector's rough piece rather than a liquid financial asset
Similar Diamonds
Comparable to unworked run-of-mine gem-quality rough diamond crystals from African or Canadian deposits
Setting Suggestions
Organic wire-wrapped pendant or custom bezel setting designed to showcase the raw, uncut mineral aesthetic
Care & Maintenance
Store separately to prevent scratching other stones; clean gently with warm soapy water and a soft brush
Interesting Facts
Rough diamonds retain the ancient geological history of their journey from the mantle, showcasing natural crystal growth marks like trigons and striations
