Not applicable (rough, uncut stone) Cut

Natural rough diamond crystal - Uncut raw crystal (orthorhombic/octahedral fragment)

Carat

Estimated 4.5 to 6.0 carats based on visual dimensions

Color

Estimated near-colorless to light brown tint (G-J range)

Clarity

Estimated Included (I1-I2) due to visible fractures and internal inclusions

Shape

Uncut raw crystal (orthorhombic/octahedral fragment)

Overall Assessment

An interesting and substantial natural rough diamond crystal with notable character, ideal for a collector or custom lapidary cutter willing to maximize yield over final clarity

Cut Quality

Not applicable (rough, uncut stone)

Brilliance

Low to moderate due to raw, unpolished surface and internal fracturing

Fire

Minimal dispersion visible through the rough, uneven surfaces

Scintillation

Limited flash due to lack of faceted angles

Proportions

N/A for raw, unpolished crystal

Symmetry

Natural crystal symmetry, highly irregular due to natural formation and fracture

Polish

Natural crystal face texture (trigons and striations visible)

Fluorescence

Cannot be definitively determined visually without UV testing (likely None to Faint)

Inclusions

Internal feather fractures, dark mineral inclusion spots, and cloudiness

Blemishes

Natural surface etchings, trigons, and surface pitting typical of rough crystals

Origin

Likely alluvial or primary kimberlite pipe deposit (African or Canadian origin)

Treatment Detection

No visible signs of artificial treatments; appears entirely untreated and natural

Estimated Value

Varies significantly depending on yield post-cutting, roughly $1,500 to $3,500 USD in rough form

Certification Estimate

GIA or local gemological laboratory for verification of natural origin

Investment Potential

Moderate, primarily valued as a collector's specimen or custom cut potential

Similar Diamonds

Other un-cut industrial or ornamental gem-quality rough diamond crystals

Setting Suggestions

Custom raw-stone bezel setting in yellow or white gold to preserve its organic form

Care & Maintenance

Store separately to prevent scratching other stones; clean with warm soapy water and a soft brush

Interesting Facts

Rough diamonds retain the geological memory of the Earth's mantle where they formed billions of years ago
