Natural rough diamond crystal showing typical octahedral growth features, curved faces, and triangular pockmarks (trigons). - Rough uncut crystal, irregular elongated octahedral form.

Carat

Estimated approximately 1.5 to 2.5 carats based on visual scale.

Color

Estimated near-colorless to slightly tinted brown/yellow (approx. G-J range).

Clarity

Estimated included (I1-I2) due to visible internal feathering, cloud formations, and surface cavities.

Shape

Rough uncut crystal, irregular elongated octahedral form.

Overall Assessment

An intriguing, natural rough diamond crystal with characteristic growth features, offering high potential for a custom-cut faceted gem or a unique raw-stone jewelry piece.

Cut Quality

Not applicable as this is an uncut, natural rough diamond crystal.

Brilliance

Limited brilliance due to unpolished and irregular surface facets, but exhibits glassy luster (adamantine).

Fire

Minimal dispersion visible in current rough state until faceted and polished.

Scintillation

Low scintillation in rough form; light reflection is scattered across uneven crystal planes.

Proportions

Not applicable for rough crystal; irregular natural dimensions.

Symmetry

Natural crystal symmetry reflecting cubic crystal habit with distorted growth faces.

Polish

Natural unpolished crystal faces showing characteristic striations and growth features.

Fluorescence

Cannot be definitively determined without UV testing, likely None to Faint blue.

Inclusions

Internal feathers, clouds, pinpoints, and potential small mineral crystals trapped during growth.

Blemishes

Natural trigons, surface etching marks, indentation pits, and irregular growth lines.

Origin

Likely alluvial or primary kimberlite pipe origin (Africa, Canada, or Russia).

Treatment Detection

No signs of artificial treatment; appears entirely natural and untreated.

Estimated Value

Varies widely based on final cut yield, estimated at $1,500 to $4,000 USD depending on cutter's skill and final polished weight.

Certification Estimate

GIA or AGS if submitted, likely receiving a rough diamond report or detailed grading post-cutting.

Investment Potential

Moderate potential as a collector's specimen or custom-cut investment piece.

Similar Diamonds

Other natural run-of-mine rough diamond crystals of similar size and clarity.

Setting Suggestions

Can be set raw/uncut in a bespoke organic bezel setting using yellow or white gold for an artisanal look.

Care & Maintenance

Clean with warm soapy water and a soft brush; store separately to prevent scratching other jewelry.

Interesting Facts

Rough diamonds display natural growth markers like trigons which are microscopic triangular etch pits formed by dissolving fluids deep within the Earth.
