Overall Assessment

A high-quality rough diamond specimen with significant potential for faceting into a large, high-value polished stone.

Cut Quality

Uncut (Rough)

Brilliance

Low (unpolished state)

Fire

Low (requires faceting for dispersion)

Scintillation

Minimal (restricted to surface reflection)

Proportions

Natural crude octahedron form

Symmetry

Asymmetrical (Natural Crystal)

Polish

Natural Texture (Trigons and growth lines)

Fluorescence

Unable to determine without UV light

Inclusions

Visible internal fractures (feathers) and possible dark crystals

Blemishes

Surface trigons, percussion marks, and natural skin textures

Origin

Likely Alluvial source (African or South American regions)

Treatment Detection

None apparent; natural untreated state

Estimated Value

$15,000 - $35,000 depending on internal yield and color

Certification Estimate

GIA Rough Diamond Inspection (Identity and Origin)

Investment Potential

High, contingent upon the potential yield of a high-grade polished stone

Similar Diamonds

Uncut gem-quality rough crystals of similar clarity and size

Setting Suggestions

Rough diamond specimen setting or custom organic tension mount

Care & Maintenance

Protect from hard impacts to prevent cleavage along natural planes

Interesting Facts

The surface features triangular 'trigons' which are classic indicators of natural diamond growth
