Natural (Rough / Uncut Diamond Crystal)
Natural (Rough / Uncut Diamond Crystal) · Rough Crystal / Natural Octahedral or Irregular Form
Not Applicable (Rough un-faceted stone) Cut
Carat
Estimated 2.50 - 3.50 carats based on visual proportions
Color
Near-Colorless to Light Yellow (Estimated K-M range)
Clarity
Included (I1 - I3 range due to visible internal fracturing and surface irregularities)
Shape
Rough Crystal / Natural Octahedral or Irregular Form
Overall Assessment
An interesting, natural rough diamond crystal displaying characteristic surface textures and internal inclusions, more suited for raw-stone jewelry designs or mineral collections than traditional faceted gemstone markets
Cut Quality
Not Applicable (Rough un-faceted stone)
Brilliance
Low to Moderate due to lack of standard facets and presence of internal inclusions
Fire
Minimal due to rough exterior and light-scattering inclusions
Scintillation
Poor due to lack of polished facets to reflect and return light
Proportions
Not Applicable for rough diamond
Symmetry
Natural asymmetric crystal growth formations
Polish
Natural crystalline faces (trigons and surface striations typical of rough diamond)
Fluorescence
Cannot be determined without UV light testing (typically Medium to Strong Blue in natural roughs of this type)
Inclusions
Heavy internal feathering, cloudiness, and dark mineral inclusions visible within the matrix
Blemishes
Natural surface pitting, rough skin, cavities, and growth hillocks
Origin
Alluvial or primary kimberlite deposit (Likely African or South American origin)
Treatment Detection
No signs of artificial treatments; entirely natural untreated rough crystal
Estimated Value
Industrial or low-grade ornamental value; approximately $300 - $800 USD depending on cutting potential
Certification Estimate
GIA or HRD (Rough Diamond Evaluation Certificate / Kimberley Process documentation required)
Investment Potential
Low investment value as a gem-grade asset; primarily valued as a collector specimen or raw material for specialized lapidary work
Similar Diamonds
Industrial-grade rough diamonds and uncut natural crystal jewelry stones
Setting Suggestions
Best suited for organic/rustic bespoke raw-diamond jewelry set in heavy yellow gold or platinum prongs
Care & Maintenance
Clean with warm soapy water and a soft brush; avoid harsh ultrasonic cleaners due to internal fracturing which could cause the stone to split along cleavage planes
Interesting Facts
This specimen displays natural growth features such as stepped faces and corrosion features formed deep within the Earth's mantle over a billion years ago
