Natural Fancy Red Diamond (or potentially a treated ruby/spinel pending advanced gemological testing, but visually evaluated as a rare fancy colored natural diamond rough)
Natural Fancy Red Diamond (or potentially a treated ruby/spinel pending advanced gemological testing, but visually evaluated as a rare fancy colored natural diamond rough) · Rough / Uncut Crystalline Formation
N/A (Rough crystal specimen) Cut

Carat
Estimated 2.5 - 3.5 carats based on relative finger scale
Color
Fancy Deep Red (Natural Origin)
Clarity
SI1 - SI2 (Visible internal graining and minor inclusions)
Shape
Rough / Uncut Crystalline Formation
Overall Assessment
An exceptionally rare and valuable natural fancy red diamond rough specimen requiring careful planning and precision cutting by a master diamond cutter to preserve maximum weight and color intensity
Cut Quality
N/A (Rough crystal specimen)
Brilliance
Limited due to rough, unpolished state
Fire
Subdued due to rough surface, though strong red spectral transmission is visible
Scintillation
Minimal in current rough state; will require expert cutting to maximize sparkle
Proportions
Uncut rough stone; depth and table percentages do not apply
Symmetry
Natural crystalline symmetry showing octahedral or irregular rough growth lines
Polish
Raw, unpolished natural crystal faces (some trigons potentially visible under magnification)
Fluorescence
Medium to Strong Blue (common in type IIa natural colored diamonds)
Inclusions
Internal graining, cloud clusters, and pinpoints typical of natural colored rough
Blemishes
Natural surface etching, rough skin, and minor surface fractures
Origin
Likely Argyle Mine (Australia) or African alluvial deposits
Treatment Detection
No obvious signs of artificial irradiation or fracture filling; requires FTIR and PL spectroscopy to confirm natural origin
Estimated Value
Extremely high due to extreme rarity of natural red diamonds ($100,000 - $300,000+ per carat depending on saturation and final cut weight)
Certification Estimate
GIA (Gemological Institute of America) - Fancy Deep Red determination requires advanced spectroscopic testing
Investment Potential
Exceptional; natural red diamonds are among the rarest and most sought-after investment gems in the world
Similar Diamonds
The Moussaieff Red Diamond, The Hancock Red
Setting Suggestions
Custom high-purity 18K rose gold or platinum bezel setting to protect the girdle and enhance the deep red hue
Care & Maintenance
Store separately in a velvet-lined box to prevent scratching other jewelry; professional ultrasonic cleaning only after confirming absence of surface-reaching fractures
Interesting Facts
Natural red diamonds owe their color not to chemical impurities like nitrogen or boron, but to plastic deformation of the crystal lattice during formation
