The duration required for the creation of these precious gemstones is a process measured in geological timescales, occurring deep within the Earth’s mantle. Extreme heat and pressure, acting on carbon atoms over vast periods, are essential conditions for their genesis.
Understanding the timeframe involved highlights the rarity and value associated with these crystalline structures. Geological processes spanning millions or even billions of years contribute to their formation, placing them among the oldest materials found on Earth and imbuing them with significant geological importance.
