Natural Fancy Red Diamond (or potentially a red gem mineral like Garnet or Spinel, pending specialized gemological testing)
Natural Fancy Red Diamond (or potentially a red gem mineral like Garnet or Spinel, pending specialized gemological testing) · Rough/Uncut crystal fragment with irregular natural contours
Not Applicable (Rough, uncut stone) Cut
Carat
Estimated 1.50 to 2.50 carats based on visual scale against fingers
Color
Fancy Intense Red to Dark Red
Clarity
Included (I1-I2 estimated due to visible internal structures and cloudiness)
Shape
Rough/Uncut crystal fragment with irregular natural contours
Overall Assessment
The specimen exhibits a striking deep red hue in backlit conditions. Given the extreme rarity of natural red diamonds, immediate formal laboratory testing (such as GIA) is strongly advised to confirm its true mineral identity and origin.
Cut Quality
Not Applicable (Rough, uncut stone)
Brilliance
Low due to unpolished and rough state
Fire
Obscured by rough surfaces and deep color body, minimal dispersion visible
Scintillation
Limited, as light return is restricted by the rough, non-faceted exterior
Proportions
Irregular rough proportions; depth percentage and table percentage do not apply
Symmetry
Asymmetrical due to natural rough crystal formation
Polish
Raw, unpolished crystalline surface with natural etching features
Fluorescence
Cannot be determined without UV lamp testing (typically moderate to strong blue in natural Type IIa colored diamonds)
Inclusions
Natural internal graining, needles, and potential cloud-like inclusions typical of rough colored diamond formation
Blemishes
Natural surface trigons, rough skin, and minor surface abrasions consistent with unpolished crystals
Origin
Natural alluvial or primary kimberlite deposit origin; Argyle mine (Australia) historical source for rare reds
Treatment Detection
Advanced spectroscopic testing required to rule out HPHT annealing or irradiation treatments
Estimated Value
Highly variable; if confirmed as a natural red diamond, value could exceed hundreds of thousands of dollars per carat; if gemstone material such as garnet or ruby, significantly lower
Certification Estimate
GIA (Gemological Institute of America) Colored Diamond Grading Report required for definitive authentication
Investment Potential
Extremely high potential if authenticated as a natural fancy red diamond due to extreme rarity
Similar Diamonds
Moussaieff Red Diamond, other rare Type IIa natural fancy red rough specimens
Setting Suggestions
Custom bezel or prong setting in 18k yellow gold or rose gold to enhance and complement the deep red hues
Care & Maintenance
Store separately in a soft pouch to prevent scratching other jewelry, clean gently with warm soapy water and a soft brush
Interesting Facts
Natural red diamonds are among the rarest colored diamonds in the world, with fewer than 30 true fancy red diamonds officially documented
