Natural rough diamond specimen - Rough / Uncut crystal fragment

Carat

Color

Light yellowish-brown / Near-colorless with tint

Clarity

I2-I3 (Included / Industrial grade rough with prominent internal fractures and inclusions)

Shape

Rough / Uncut crystal fragment

Overall Assessment

An interesting, unpolished natural diamond rough specimen displaying typical raw crystal texture and yellowish coloration, suited primarily for mineral collections or specialized artisan jewelry rather than traditional faceted gem use

Cut Quality

Not applicable (uncut rough specimen)

Brilliance

Low, limited to surface reflection on rough planes

Fire

Minimal dispersion visible due to rough, unpolished surface

Scintillation

Poor, lacking faceted return of light

Proportions

Irregular raw crystal proportions

Symmetry

Natural asymmetric crystal growth

Polish

Raw, unpolished natural crystal faces and fracture surfaces

Fluorescence

Indeterminate from visual assessment alone, likely inert to faint blue

Inclusions

Heavy internal clouding, feather fractures, and potential mineral inclusions

Blemishes

Natural surface etch channels, trigons, and rough skin textures

Origin

Natural alluvial or primary kimberlite/lamproite deposit source

Treatment Detection

No obvious signs of artificial treatment; untreated natural rough

Estimated Value

Low commercial value as industrial rough or mineral specimen

Certification Estimate

Gemological laboratories would classify this as rough mineral specimen; requires cutting for standard GIA grading

Investment Potential

Low investment value; primarily of educational or specimen interest

Similar Diamonds

Typical industrial-grade run-of-mine natural diamond rough

Setting Suggestions

Best kept as a raw mineral specimen or custom-set in organic wire-wrap jewelry

Care & Maintenance

Store carefully to avoid edge chipping along natural cleavage planes; clean gently with warm soapy water

Interesting Facts
