Overall Assessment

An interesting specimen of a natural, uncut diamond crystal displaying characteristic rough morphology, best suited for raw gemstone collections or custom organic jewelry rather than standard high-end cutting

Cut Quality

Not applicable (uncut rough stone)

Brilliance

Low (due to rough, unpolished surface)

Fire

Minimal visible fire on raw surfaces

Scintillation

Poor due to lack of faceted geometry

Proportions

Natural rough formation, uneven depth and dimensions

Symmetry

Natural crystal symmetry, distorted octahedron

Polish

Natural crystal faces (trigons and striations present)

Fluorescence

Cannot be determined visually without UV testing

Inclusions

Internal cloudiness, carbon spots, and feather fractures visible

Blemishes

Natural surface pitting, rough skin, and trigons

Origin

Alluvial or primary kimberlite deposit origin

Treatment Detection

No signs of artificial treatment; completely natural rough state

Estimated Value

Varies significantly based on cutting potential, roughly $300 to $800 USD

Certification Estimate

GIA rough report or local gemological laboratory authentication

Investment Potential

Low investment value as gem-grade; primarily of interest to collectors or lapidaries

Similar Diamonds

Setting Suggestions

Raw mineral jewelry setting using a secure wire-wrap or prong basket in yellow or white gold

Care & Maintenance

Store separately to prevent scratching other softer gemstones; clean with mild soapy water and a soft brush
