It's been said that diamonds are forever — probably because "diamonds are billion-year-old mutant rocks exposed to many lifetimes of crushing pressures and scorching temperatures in Earth's deep mantle" doesn't have the same snappy ring to it. Either way, it takes a long, long time for a chunk of carbon to crystallize into a sparkling diamond — so long, in fact, that scientists aren't positive how they're made. One popular theory maintains that many diamonds form when slabs of seabed part of an oceanic plate grind underneath continental plates at so-called tectonic subduction zones.
CNN Millions of years ago, precious gem stones from the heart of southern Africa washed westward along the Orange River and emptied into the Atlantic Ocean. Chat with us in Facebook Messenger. Find out what's happening in the world as it unfolds.
As precious and sought-after as diamonds are, we know relatively little about the complicated process that goes into creating these gems in nature. This is largely because they are usually pushed to the surface — where we can reach them — by volcanic eruptions after being formed deep underground. But scientists have now discovered a crucial element in the formation of most natural diamonds: sediment from the sea floor.

By Rae Steinbach Diamond mining has traditionally been restricted to the land. However, recent developments are changing that.
Mines are created to recover these magnificent artifacts, sometimes so large they can be seen from space. What may come as somewhat of a surprise though, is the fact that diamonds can be found beneath the ocean as well! Sign up to receive exclusive updates and special offers.
