Natural rough diamond crystal - Rough crystal / Uncut octahedral or irregular elongation

Carat

Estimated 3.50 to 5.00 carats based on visual scale against fingers

Color

Near-colorless to faint tint (approx. G-J range)

Clarity

Included (approx. I1 to I2) due to visible dark mineral inclusions and feathers

Shape

Rough crystal / Uncut octahedral or irregular elongation

Overall Assessment

An intriguing natural rough diamond crystal showing characteristic surface features, raw texture, and internal inclusions, holding great potential if faceted by an expert master cutter.

Cut Quality

Not applicable (Rough, uncut specimen)

Brilliance

Low to moderate in rough form; will increase significantly upon cutting and polishing

Fire

Subdued in rough state; dependent on final pavilion angles and polish

Scintillation

Minimal play of light currently due to rough, unpolished surface facets

Proportions

Natural rough proportions, heavily dependent on future cutting plan

Symmetry

Natural asymmetrical crystal growth formation

Polish

Natural crystalline surface texture (trigons and striations typical of rough diamonds)

Fluorescence

Indeterminate from visual inspection alone (typically tested via UV lamp)

Inclusions

Visible dark mineral inclusions, internal fractures (feathers), and cloudiness

Blemishes

Natural surface pitting, rough skin, and possible abrasions from extraction

Origin

Alluvial or primary kimberlite pipe deposit (exact mine unknown without internal inclusion analysis)

Treatment Detection

No treatments detected; appears entirely untreated in natural rough state

Estimated Value

Varies widely depending on yield after cutting, rough industrial to gem-grade value ranging from hundreds to a few thousand dollars

Certification Estimate

GIA or similar major lab upon submission for professional grading post-cut

Investment Potential

Speculative, as value depends entirely on the potential polished yield and master cutting loss

Setting Suggestions

Can be mounted raw in organic or rustic bespoke jewelry designs, or cut into a modern brilliant shape for standard settings

Care & Maintenance

Store separately to prevent scratching other softer gemstones, clean with mild soapy water and a soft brush

Interesting Facts

Rough diamonds like this have traveled billions of years from the Earth's mantle via explosive volcanic kimberlite eruptions
