Carat
Estimated 3.50 - 5.00 carats based on visual proportions
Color
Fancy Deep Red / Brown-Red
Clarity

Shape
Irregular Slice / Rough Crystal
Overall Assessment
An intriguing, deeply colored rough diamond or mineral slice exhibiting rich red hues and natural irregularities. While lacking standard optical properties of faceted gemstones, it holds unique value as an organic collector specimen.
Cut Quality
Poor / Rough Mineral Slice
Brilliance
Low due to lack of standard faceted geometry and heavy internal inclusions
Fire
Minimal, constrained by deep body color and inclusion density
Scintillation
Low, limited to surface reflections
Proportions
Variable depth and uneven thickness typical of a rough slice
Symmetry
Poor / Asymmetrical natural formation
Polish
Rough sawn / Unpolished surface texture
Fluorescence
Unknown / Untested visually
Inclusions
Heavy internal clouds, natural fissures, mineral inclusions, and structural variations
Blemishes
Natural surface pitting, rough edges, and saw marks
Origin
Natural rough mineral source, possibly alluvial or direct from primary kimberlite pipe with natural or induced coloration
Treatment Detection
Potential surface irradiation or natural coloration; standard spectroscopic testing required to rule out lab treatment
Estimated Value
$500 - $1,500 depending on exact mineral composition and unique collector appeal
Certification Estimate
GIA or AGS would classify as a natural rough or unusual mineral slice with fancy color treatment indicators
Investment Potential
Low to moderate liquidity; valued primarily as a unique collector's specimen or bespoke jewelry piece rather than a standard investment grade diamond
Similar Diamonds
Fancy colored rough diamond slices, raw carbonados, or heavily included fancy colored industrial stones
Setting Suggestions
Wire-wrapped pendant or custom bezel setting to showcase the organic, raw slice aesthetic
Care & Maintenance
Avoid ultrasonic cleaners and harsh chemicals; protect from physical impacts due to internal structural vulnerabilities along natural cleavage planes
Interesting Facts
Natural red diamonds are among the rarest colored diamonds in the world, typically deriving their color from plastic deformation in the crystal lattice rather than chemical impurities
