Rough Natural Diamond Crystal
Rough Natural Diamond Crystal · Uncut Rough Crystal (Elongated Octahedral/Resin-like habit)
Not Applicable (Uncut Rough) Cut
Carat
Estimated 3.50 to 5.00 carats
Color
Light Greenish-Yellow / Faint Yellowish Tint (Cape Series)
Clarity
Included (I1-I2 estimated due to extensive internal fracturing and mineral inclusions)
Shape
Uncut Rough Crystal (Elongated Octahedral/Resin-like habit)
Overall Assessment
An interesting, sizable natural rough diamond crystal displaying characteristic surface etching and internal inclusions, offering potential as an educational specimen or for rustic jewelry design.
Cut Quality
Not Applicable (Uncut Rough)
Brilliance
Low to Moderate due to rough, unpolished surface and internal inclusions
Fire
Minimal in current rough state; will display standard diamond dispersion once faceted
Scintillation
Limited flash effect across raw window surfaces
Proportions
Natural elongated crystal form, high depth percentage typical of rough recovery
Symmetry
Natural Asymmetric Crystal Growth
Polish
Natural Unpolished Surface with Etch Channels
Fluorescence
Indeterminate from visual assessment (typically Medium to Strong Blue in natural roughs of this type under UV)
Inclusions
Heavy internal feathering, cloudiness, and dark mineral spots visible throughout the core
Blemishes
Natural surface trigons, etch marks, and minor chip points from extraction
Origin
Likely alluvial or primary kimberlite pipe origin (Africa or South America)
Treatment Detection
No evidence of artificial treatments; entirely natural untreated rough specimen
Estimated Value
Varies significantly by final cut potential; rough specimen value estimated around $500 - $1,500 USD
Certification Estimate
GIA or similar major laboratory would issue a Diamond Rough Report or Grading Report upon cutting
Investment Potential
Moderate as a collector specimen, but low for commercial investment compared to polished high-clarity stones
Similar Diamonds
Industrial or low-gem grade natural rough diamond crystals of similar size and clarity
Setting Suggestions
Best suited for custom organic, rustic, or raw-diamond jewelry designs utilizing a bezel or prong setting to secure the irregular shape
Care & Maintenance
Avoid harsh ultrasonic cleaners due to internal fracturing; clean gently with warm soapy water and a soft brush
Interesting Facts
Rough diamonds retain their natural geological memory, showcasing crystal growth patterns that disappear once cut and polished
