National Day

(Monthly) National Black Diamond Month

Celebrated on 01/01/2026

Quick Fact

Black diamonds, also known as carbonado, are found almost exclusively in Brazil and the Central African Republic, and they are believed to have originated from a meteorite impact or even a supernova explosion over 2.6 billion years ago. Unlike traditional diamonds, carbonado is porous and extremely tough, making it ideal for industrial uses like cutting tools.

Origins and Establishment of (Monthly) National Black Diamond Month

National Black Diamond Month was established in 2020 by the Black Diamond Foundation, a nonprofit organization dedicated to promoting the appreciation and understanding of black diamonds (carbonado). The month-long observance was created to highlight the unique geological origins, historical significance, and industrial applications of these rare diamonds. The foundation chose February as the celebration month to align with Black History Month, emphasizing the cultural and historical ties of black diamonds to Africa and the African diaspora.

Evolution and Modern Commemoration

Since its inception, National Black Diamond Month has evolved from a niche observance into a global campaign involving gemological institutes, museums, and jewelry retailers. Initially focused on educational events and exhibitions, the month now includes online webinars, social media campaigns, and special sales of black diamond jewelry. In 2023, the event expanded to include partnerships with African art galleries and historical societies to explore the cultural significance of carbonado in Brazilian and Central African heritage. Modern commemoration often features virtual tours of diamond mines and laboratories, as well as discussions on ethical sourcing and sustainability.

Facts & General Observations

  • Black diamonds are the hardest known natural material, scoring a 10 on the Mohs scale, but their polycrystalline structure makes them tougher and less brittle than white diamonds.
  • Carbonado diamonds are only found in alluvial deposits in Brazil and the Central African Republic, with no known kimberlite sources, supporting the theory of extraterrestrial origin.
  • Despite their rarity, black diamonds are generally less expensive than white diamonds due to lower demand in the jewelry market, though high-quality specimens can fetch prices comparable to fancy colored diamonds.
