New research has found that black diamonds, or carbonato diamonds, are of extraterrestrial origin. All other known types of diamonds were formed deep within the Earth and are mined from the volcanic rock which transports them to the surface. Black diamonds, however, are not found alongside other diamonds and are found only in Brazil and the Central African Republic. The researchers determined that black diamonds contained increased hydrogen content, supporting the previous hypothesis that black diamonds were formed in supernovae. Supernovae are stellar explosions which produce extremely bright balls of plasma, often briefly outshining whole galaxies before fading to obscurity. When black diamonds reached Earth, they were an astronomic size of one kilometer or greater. So, what better way to affirm your cosmic connection than proposing with an oversized black diamond solitaire? No need to worry your intergalactic soul mate with the factoid that black diamonds are in fact cheaper than most other diamonds. And really, who cares when you could wear a piece of a fallen star on your hand? That’s got to be good luck.
