Natural Fancy Red Diamond (or potentially a red gemstone such as ruby/spinel pending physical testing, but evaluated as a rare fancy colored diamond based on appearance)
Natural Fancy Red Diamond (or potentially a red gemstone such as ruby/spinel pending physical testing, but evaluated as a rare fancy colored diamond based on appearance) · Rough / Uncut Crystal (Sub-angular, distorted crystal habit)
Not Applicable (Uncut rough crystal) Cut

Carat
Approximately 1.5 to 2.5 carats based on visual scale against fingers
Color
Fancy Deep Red / Natural Red
Clarity
Included (I1-I2 in rough form, with prominent natural surface features and internal inclusions)
Shape
Rough / Uncut Crystal (Sub-angular, distorted crystal habit)
Overall Assessment
An exceptionally rare and striking deep red crystal specimen. If authenticated as a natural fancy red diamond rather than another red gemstone, it represents an ultra-high-value collector's piece requiring professional laboratory certification.
Cut Quality
Not Applicable (Uncut rough crystal)
Brilliance
Low in rough state, limited to localized internal reflection
Fire
Minimal dispersion visible through rough, unpolished curved faces
Scintillation
Poor due to lack of standard facet arrangement in rough form
Proportions
Natural rough proportions, unpolished crystal dimensions
Symmetry
Natural crystal symmetry, distorted octahedron/irregular form
Polish
Raw crystal faces (natural trigons and striations expected)
Fluorescence
Moderate to Strong (Typical for many natural red and pink diamonds under UV light)
Inclusions
Internal cloudiness, feather fractures, and dark mineral crystals visible
Blemishes
Natural surface pitting, rough skin, and possible abrasions from handling
Origin
Argyle Mine (Australia) or African alluvial deposits historically known for colored diamonds
Treatment Detection
No obvious signs of artificial irradiation or coating, but advanced spectroscopy needed to rule out HPHT treatment
Estimated Value
Extremely high if confirmed as a genuine natural red diamond (millions per carat for pure fancy red); subject to verification of mineral species
Certification Estimate
GIA (Gemological Institute of America) - Colored Diamond Report required for verification
Investment Potential
Exceptionally high rarity value, making it a museum-grade or elite collector asset if certified natural
Similar Diamonds
Hancock Red, Moussaieff Red Diamond, or other rare naturally occurring red diamonds
Setting Suggestions
Custom multi-prong platinum or 18k yellow gold basket setting to enhance the rich red hue once cut, or preserved as a unique collector's rough specimen
Care & Maintenance
Store separately in a padded gem jar to avoid scratching other stones; avoid harsh ultrasonic cleaners due to internal fractures
Interesting Facts
Natural red diamonds are among the rarest gems on Earth, with fewer than 30 true fancy red diamonds known to exist with significant size
