Revisiting the Rarity of Diamonds: New Research Challenges Old Beliefs.
TL;DR
New research suggests that diamonds may be rarer than previously thought, and that they are formed alongside a distinct purple companion, pyrope garnet, which is found both near and inside diamonds. Using a thermodynamic computer model, researchers have demonstrated that pyrope garnets can form very deep in the Earth, at the same depths as diamonds. The study also suggests that the roots of continents are leftovers from the same mantle melting events that produced pyrope garnets, and that diamonds may have always been rare due to their affinity for these particular rocks.
