Natural (Rough Crystal / Industrial or Bort Grade) - Rough Uncut Octahedron / Irregular Crystal

Carat

Estimated 1.5 - 2.5 carats

Color

Brownish / Off-Color (Low grade for cutting, likely near J-K or lower, or industrial brown)

Clarity

I3 / Included (Heavy natural inclusions, fractures, and cloudiness)

Shape

Rough Uncut Octahedron / Irregular Crystal

Overall Assessment

An untreated, natural rough diamond crystal of low clarity and dark coloration, suitable as a raw mineral specimen rather than a polished gemstone

Cut Quality

Not Applicable (Rough, uncut stone)

Brilliance

Poor to minimal (due to rough surface and heavy internal inclusions)

Fire

Very low to none in current state

Scintillation

Minimal to none due to lack of faceted surfaces

Proportions

Natural uncut proportions; deep unoptimized rough morphology

Symmetry

Natural crystal symmetry (distorted octahedron/rounded edges)

Polish

Unpolished natural crystal faces (some etched features)

Fluorescence

Indeterminate (Cannot be assessed visually without UV testing)

Inclusions

Heavy internal clouding, feathers, carbon spots, and stress fractures

Blemishes

Natural surface etching, trigons, pitting, and rough skin

Origin

Alluvial or primary kimberlitic deposit (African or Canadian origin likely)

Treatment Detection

No signs of artificial treatment; completely natural rough stone

Estimated Value

Low commercial value (primarily specimen, industrial abrasive, or low-tier cutting material value, estimated under $50 USD)

Certification Estimate

Industrial or uncertified rough lot grading; not viable for standard GIA/AGS luxury grading report

Investment Potential

Low investment potential; useful mainly as a mineral specimen or educational piece

Similar Diamonds

Typical industrial-grade rough diamonds and uncut mineral specimens

Setting Suggestions

Wire-wrapped organic rough jewelry setting or custom raw mineral prong setting in yellow or rose gold

Care & Maintenance

Handle with care to avoid chipping along natural cleavage planes; clean gently with warm soapy water and a soft brush

Interesting Facts

Rough diamonds display natural crystal growth marks called trigons and often require significant weight loss during cutting to yield a clean faceted gem
