Overall Assessment
An interesting and authentic natural rough diamond crystal in raw form, featuring significant inclusions and natural surface characteristics that make it more suitable as a mineral specimen than for commercial jewelry cutting
Cut Quality
Not Applicable (Uncut Rough)
Brilliance
Low brilliance due to rough, unpolished surface and internal inclusions
Fire
Minimal dispersion visible through the rough exterior
Scintillation
Poor light return and flashing due to lack of standard facet geometry
Proportions
Not Applicable for rough crystal formation
Symmetry
Natural irregular octahedral/elongated crystal form
Polish
Natural crystal faces, unpolished rough surface with minor pitting
Fluorescence
Cannot be definitively assessed without UV testing, likely Faint to Medium
Inclusions
Heavy internal feathers, cloudiness, mineral inclusions, and dark carbon spots visible
Blemishes
Surface cavities, trigons on crystal faces, natural surface etching, and adhering matrix minerals
Origin
Likely alluvial or primary kimberlite deposit origin from an African or South American source
Treatment Detection
No treatments detected; entirely untreated, natural rough stone
Estimated Value
Low commercial value, primarily valued as a specimen or for industrial applications, roughly $100 - $300 depending on actual weight
Certification Estimate
Gemological lab (GIA/EGL) would issue a rough diamond report or grade as industrial/promotional quality if cut
Investment Potential
Low investment potential for resale, primarily collectible mineral specimen value

Setting Suggestions
Best preserved as a raw mineral specimen or set in a custom organic wire-wrap or bezel setting highlighting its natural form
Care & Maintenance
Store separately to prevent scratching other stones; clean gently with warm soapy water and a soft brush
Interesting Facts
Rough diamonds retain their natural geological history, showing crystal growth features such as striations and trigons formed millions of years ago deep within the Earth's mantle
