Not applicable as this is an uncut rough crystal specimen Cut

Rough natural diamond crystal fragment - Uncut or partially fractured tabular/elongated crystal

Carat

Estimated 2.0 to 3.5 carats based on visual scale against fingers

Color

Estimated near-colorless to light brown tint (approx. G-I range)

Clarity

Estimated included (I1-I2) with noticeable internal fractures and surface irregularities

Shape

Uncut or partially fractured tabular/elongated crystal

Overall Assessment

This is an interesting, natural rough diamond fragment exhibiting characteristic growth planes and fractures. While not suitable for immediate jewelry use without cutting and polishing, it represents an authentic geological specimen with potential for custom lapidary work.

Cut Quality

Not applicable as this is an uncut rough crystal specimen

Brilliance

Low to moderate due to raw, unfaceted surface scattering light

Fire

Minimal dispersion observed in current rough state

Scintillation

Limited, primarily flashes from cleavage planes rather than facet patterns

Proportions

Irregular raw crystal shape; standard faceted proportions do not apply

Symmetry

Natural crystal growth symmetry, highly irregular due to fracture

Polish

Natural crystal face texture with rough conchoidal fracture surfaces

Fluorescence

Unable to determine without UV light testing (likely None to Faint)

Inclusions

Feathers, internal cleavage planes, and dark mineral inclusions visible

Blemishes

Natural surface trigons, rough fractures, and surface etching

Origin

Likely alluvial or primary kimberlite/lamproite deposit origin

Treatment Detection

No signs of enhancement; appears completely untreated and natural

Estimated Value

Varies significantly as a specimen; lower gem-grade value estimated around $300 to $800 depending on cutting yield

Certification Estimate

GIA or IGI would issue a rough diamond origin report if submitted

Investment Potential

Moderate value as a raw specimen for collectors, lower investment potential compared to finished investment-grade polished stones

Similar Diamonds

Comparable to standard industrial or lower-tier gem-quality rough diamond parcels

Setting Suggestions

Best preserved as a raw mineral specimen in a custom organic wire-wrap or bespoke raw-stone bezel setting

Care & Maintenance

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

Interesting Facts

Rough diamonds retain the ancient geological memory of their journey from the Earth's mantle, often displaying natural growth markings like trigons
