Natural Fancy Colored Diamond (Chameleon or Irradiated Red/Brown Diamond crystal rough)
Natural Fancy Colored Diamond (Chameleon or Irradiated Red/Brown Diamond crystal rough) · Raw crystal / Rough elongated form
Not applicable (uncut crystal rough) Cut
Carat
Estimated 2.0 to 3.0 carats
Color
Fancy Deep Red / Orange-Red
Clarity
SI1 to SI2 (estimated for rough state)
Shape
Raw crystal / Rough elongated form
Overall Assessment
An intriguing and vibrant deep red rough crystal holding immense potential for high-end custom cutting, subject to rigorous gemological laboratory testing to verify its natural color origin
Cut Quality
Not applicable (uncut crystal rough)
Brilliance
Varies by facet/windowing; limited due to rough, unpolished state
Fire
Strong red and amber spectral dispersion visible where light transmits through fractures and cleavage planes
Scintillation
Limited in rough state, will improve significantly upon proper cutting and polishing
Proportions
N/A - Natural rough crystal morphology
Symmetry
Natural crystal symmetry, typical of octahedral/twinned rough elongation
Polish
Natural crystal face luster (unpolished)
Fluorescence
Medium to Strong Yellowish-Green (typical for certain natural colored roughs under UV)
Inclusions
Internal cloud formations, needles, and natural growth lines characteristic of rough colored diamonds
Blemishes
Natural surface etch channels, trigons, and rough skin textures
Origin
Likely natural origin, potentially from historical African or Australian deposits known for colored diamonds
Treatment Detection
Advanced spectroscopic testing required to rule out artificial irradiation or surface coating
Estimated Value
Highly variable due to rarity; natural red diamonds command premium prices, potentially $10,000 to $50,000+ per carat depending on saturation and final cut weight
Certification Estimate
GIA Colored Diamond Report
Investment Potential
Exceptional due to extreme rarity of natural fancy red diamonds in the marketplace
Similar Diamonds
Comparable to rare Argyle pink or red rough diamonds and intense fancy colored natural stones
Setting Suggestions
Custom artisan prong setting in yellow or rose gold to complement the deep red/orange hue
Care & Maintenance
Standard ultrasonic cleaning with caution; avoid harsh chemicals and protect from impact to prevent cleavage fracture
Interesting Facts
Natural red diamonds are among the rarest colored diamonds in the world, often possessing defects in the crystal lattice that cause red absorption bands
