Natural Rough Diamond
Natural Rough Diamond · Rough / Uncut
Uncut/None Cut
Carat
Estimated 2.0 - 5.0 carats based on visual scale
Color
Near Colorless (estimated G-I range)
Clarity
Included (I1-I2 equivalent in rough state)
Shape
Rough / Uncut
Overall Assessment
A natural rough diamond crystal showing characteristic glassy luster and irregular shape. The presence of surface markings and internal fractures suggests a specimen grade or industrial to low-gem quality piece.
Cut Quality
Uncut/None
Brilliance
Low (typical for unpolished diamond)
Fire
Low (inhibited by rough surface)
Scintillation
Minimal (due to lack of facets)
Proportions
Irregular / Crystalline
Symmetry
Very Poor (Asymmetric rough state)
Polish
Unpolished / Natural surface
Fluorescence
Cannot determine without UV light
Inclusions
Visible structural fractures, possible dark crystal inclusions and red mineral spotted on surface.
Blemishes
Surface trigons, percussion marks, and natural skin textures.
Origin
Likely African (e.g., Botswana or DRC) or Canadian
Treatment Detection
None apparent; looks natural uncut
Estimated Value
$1,500 - $4,000 depending on internal quality and yield potential
Certification Estimate
GIA (Rough Diamond Report)
Investment Potential
Low to Moderate; rough diamonds are highly speculative until cut.
Similar Diamonds
Uncut octahedral crystals of similar weight
Setting Suggestions
Rough diamond prong setting or pendant cage in 14k/18k gold.
Care & Maintenance
Clean with warm soapy water and a soft brush; avoid sharp impacts on fracture lines.
Interesting Facts
Rough diamonds often have triangular markings on their surfaces called trigons, which indicate their cubic crystal growth.
