The shape of a diamond depends on the conditions under which it grows
2 years ago
4.13K
Which shape a particular diamond grows into depends on the conditions where it grows, including pressure, temperature, and chemical environment. While we can’t directly observe growth conditions in the mantle, laboratory experiments have shown some evidence that diamonds tend to grow into cubes at lower temperatures and octahedrons at higher temperatures. Trace amounts of water, silicon, germanium, or magnesium might also influence a diamond’s shape.
