Natural rough diamond crystal embedded in matrix · Rough crystal / Irregular octahedral fragment

Not Applicable (Uncut rough specimen) Cut

Natural rough diamond crystal embedded in matrix - Rough crystal / Irregular octahedral fragment

Carat

Estimated 2.50 - 3.50 carats in rough state

Color

Near-colorless to light brown tint (approx. J-K range)

Clarity

Included (I1 - I2 due to internal feathers and crystal inclusions)

Shape

Rough crystal / Irregular octahedral fragment

Overall Assessment

An interesting and authentic natural rough diamond specimen exhibiting classic crystal morphology and surface textures, offering potential for lapidary work or raw jewelry design

Cut Quality

Not Applicable (Uncut rough specimen)

Brilliance

Low in rough state; will increase significantly upon cutting and faceting

Fire

Obscured by rough surface texture; potential is present once faceted

Scintillation

Minimal play of light on rough faces; will be established upon proper pavilion and crown cutting

Proportions

Natural crystal habit; non-standard proportions

Symmetry

Natural octahedral symmetry distorted by growth patterns

Polish

Natural unpolished crystal faces (trigons and striations visible)

Fluorescence

Unable to determine without UV testing (Likely Faint to Medium Blue)

Inclusions

Internal feathers, carbon spots, and cloud formations visible within the rough

Blemishes

Natural surface fractures, pitting, and adhering matrix material

Origin

Likely alluvial or primary kimberlite pipe deposit (African or Canadian origin)

Treatment Detection

None detected; completely untreated natural rough stone

Estimated Value

$1,500 - $3,500 USD depending on final cutting yield and clarity retention

Certification Estimate

GIA or EGL for rough evaluation and subsequent polished report

Investment Potential

Moderate, primarily as a collector's mineral specimen or speculative raw material for custom cutting

Similar Diamonds

Comparable to standard industrial-to-near-gem grade run-of-mine African rough diamonds

Setting Suggestions

Can be set in its raw, uncut form in a bespoke organic bezel setting, or faceted into a cushion or round brilliant shape

Care & Maintenance

Avoid harsh acids and ultrasonic cleaners while in rough matrix form; store separately to prevent scratching other gemstones

Interesting Facts

Rough diamonds display natural triangular growth marks called trigons on their crystal faces, formed millions of years ago deep within the Earth's mantle
