Carat
Estimated 1.5 to 2.5 carats
Color
Near-colorless to light brown tint (approx. G-I range)
Clarity
Included (I1-I2 equivalent due to internal imperfections)
Shape
Rough / Uncut crystal form with rounded natural surfaces
Overall Assessment
This is an interesting, natural rough diamond crystal displaying characteristic curved growth lines and surface textures. While it contains visible inclusions and lacks the optical performance of a faceted stone, it holds unique appeal for mineral collectors and custom organic jewelry designers.
Cut Quality
Not applicable (uncut rough specimen)
Brilliance
Low to moderate due to rough surfaces and internal inclusions
Fire
Limited dispersion due to lack of faceted cut
Scintillation
Minimal sparkle; reflections come from curved natural faces
Proportions
Natural morphology, irregular elongated shape
Symmetry
Asymmetrical natural crystal growth
Polish
Natural unpolished crystal faces and resorption features
Fluorescence
Cannot be determined visually without UV testing
Inclusions
Visible internal mineral inclusions, feather fractures, and cloudiness
Blemishes
Natural surface etching, trigons, and surface pitting typical of alluvial or primary deposits
Origin
Likely alluvial deposit origin (Africa or South America)
Treatment Detection
No treatments detected; completely natural rough state
Estimated Value
Varies widely based on potential yield if cut, roughly $200 - $600 USD as a rough specimen
Certification Estimate
GIA (Origin Report) or similar major laboratory for rough certification
Investment Potential
Collector value depends on rarity and whether it is kept as a specimen or faceted
Similar Diamonds
Comparable alluvial rough diamond crystals of similar size and clarity
Setting Suggestions
Can be wire-wrapped in raw form using yellow gold or platinum for an organic, rustic jewelry design
Care & Maintenance
Store separately from other gems to avoid scratching other jewelry; clean gently with warm soapy water and a soft brush
