Natural diamond rough crystal (or mineral specimen) - Rough crystal / Uncut octahedral or irregular crystalline form

Carat

Estimated 2.5 - 4.0 carats based on visual scale against fingers

Color

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

Clarity

Included (I1-I2 estimated due to visible internal inclusions and surface features)

Shape

Rough crystal / Uncut octahedral or irregular crystalline form

Overall Assessment

An intriguing natural diamond rough specimen displaying classic crystal growth lines and surface features. While its current clarity and rough state limit its immediate jewelry application, it holds significant appeal as a raw mineral specimen or a candidate for custom cutting by an expert lapidary.

Cut Quality

Not applicable (Rough, uncut stone)

Brilliance

Low to moderate due to rough, unpolished surface hindering light return

Fire

Low due to lack of faceted optical geometry

Scintillation

Minimal, localized to specific reflective crystal planes

Proportions

Natural crystal habit, non-standardized proportions

Symmetry

Natural asymmetrical crystal growth

Polish

Natural rough crystal faces (trigons and striations visible)

Fluorescence

Cannot be determined without UV testing (Likely none to faint blue)

Inclusions

Internal feathers, clouds, and pinpoint inclusions typical of rough diamond formation

Blemishes

Natural surface pitting, trigons, and growth lines on crystal faces

Origin

Alluvial or primary kimberlite pipe deposit (Africa, Canada, or Russia)

Treatment Detection

No signs of artificial treatment; completely untreated natural rough

Estimated Value

$500 - $1,500 depending on cutting yield and final polished outcome

Certification Estimate

GIA (Gemological Institute of America) rough diamond evaluation report

Investment Potential

Moderate, primarily valued as a collector's mineral specimen or for custom cutting potential

Similar Diamonds

Unmenthable industrial or lower-gem grade octahedral and irregular rough diamond crystals

Setting Suggestions

Organic raw-stone pendant necklace or bespoke rustic ring setting utilizing prongs or bezel

Care & Maintenance

Store separately to avoid scratching other gems; clean with mild soapy water and a soft brush

Interesting Facts

The striations visible on the surface are growth lines formed deep within the Earth's mantle under extreme pressure and temperature
