Subdued due to rough, unpolished state

Fire

Limited in raw state, but hints of strong dispersion under direct lighting

Scintillation

Minimal in rough form; dependent on future cutting and faceting

Proportions

Natural uncut morphology showing octahedral and triangular growth features

Symmetry

Natural Crystal Symmetry

Polish

Raw Crystal Surface (Unpolished)

Fluorescence

Medium to Strong Blue (common in natural red diamonds)

Inclusions

Internal cleavage planes, twinning lines, and minor pinpoints characteristic of rough diamond

Blemishes

Investment Potential

Exceptional. Natural red diamonds are among the rarest gem-grade materials on Earth and consistently appreciate significantly in value

Similar Diamonds

Comparable to famous historical natural red diamonds such as the Moussaieff Red

Setting Suggestions

Custom multi-prong platinum or 18k yellow gold basket to enhance and complement the rare red hue, often accented with colorless side diamonds

Care & Maintenance

Store separately in a lined jewelry box to prevent scratching other stones. Clean gently using warm soapy water and a soft brush; avoid harsh ultrasonic cleaners until faceted and inspected

Interesting Facts

Natural red diamonds derive their color not from chemical impurities like nitrogen or boron, but from plastic deformation of the crystal lattice during formation. Fewer than 30 true fancy red diamonds over 1 carat are known to exist worldwide
