Ever wonder how diamonds make it from deep inside the Earth to your jewelry box? Turns out, they need a wild magma ride powered by at least 8.2% carbon dioxide! Without enough CO2, the diamonds just don’t make it—literally, they’d turn to graphite before reaching the surface. Scientists figured this out by modeling magma from Canada’s Jericho kimberlite, and now we know why some diamond pipes are loaded while others are duds. Science is basically geology’s version of The Amazing Race! #Science #diamonds #science
