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
