Natural
Natural · Rough crystal / Natural irregular fragment
Not applicable (Rough, un-faceted stone) Cut
Carat
Estimated 2.50 to 3.50 carats based on visual proportions
Color
Natural Fancy Deep Red / Orange-Red
Clarity
Included (I1 to I2 equivalent for rough material)
Shape
Rough crystal / Natural irregular fragment
Overall Assessment
An exceptionally rare piece of rough natural red diamond material showing strong saturation, requiring professional laboratory certification to confirm natural origin and rule out treatments
Cut Quality
Not applicable (Rough, un-faceted stone)
Brilliance
Limited due to rough surface and opaque/translucent nature
Fire
Subdued due to rough surface, though strong red body color dominates
Scintillation
Low, visible mainly as surface flash effects on unpolished planes
Proportions
Uncut crystal rough, proportions do not apply in standard cut terms
Symmetry
Asymmetrical natural crystal form
Polish
Raw, unpolished surface with natural growth features (trigons)
Fluorescence
Medium to Strong yellow/orange under UV light typical of certain natural type Ib/IIa red diamonds
Inclusions
Internal cloud-like formations, internal graining, and micro-fractures
Blemishes
Natural surface textures, pitting, and resorption features
Origin
Argyle Mine, Australia or alluvial deposits globally known for colored diamonds
Treatment Detection
Advanced spectroscopic testing needed to rule out HPHT color enhancement or irradiation
Estimated Value
Extremely high due to extreme rarity of natural red diamonds, highly speculative ranging from $50,000 to $200,000+ per carat depending on exact weight and lab results
Certification Estimate
GIA (Gemological Institute of America) would be required to verify natural color origin; likely report stating Natural Fancy Red
Investment Potential
Exceptional investment potential due to extreme scarcity and high appreciation rates for colored diamonds
Similar Diamonds
Famous natural red diamonds such as the Moussaieff Red
Setting Suggestions
Custom designer bezel setting in platinum or 18k yellow gold to protect edges and enhance warm tones
Care & Maintenance
Avoid ultrasonic cleaners and harsh chemicals; store separately to prevent scratching other gemstones
Interesting Facts
Natural red diamonds are among the rarest colored diamonds in the world, often containing lattice deformation rather than chemical impurities
