Can gold mine diamond?

Gold and Diamond Have Very Different Geological Origins

Gold forms in hydrothermal veins, diamond forms deep in the mantle

Gold is a native elemental metal that forms in hydrothermal veins and other high-temperature environments closer to the Earth’s surface. Diamond is a crystalline form of carbon that forms deep in the Earth’s mantle under intense heat and pressure. Their formation processes are completely disconnected.

Gold is an element, diamond is a compound

Gold is a native elemental metal, while diamond is a crystalline arrangement of carbon atoms. An element like gold cannot produce a compound like diamond.

Gold is soft, diamond is the hardest mineral

With a Mohs hardness of just 2.5-3, gold is a very soft metal that would not be able to cut or shape the extremely hard diamond, which has a Mohs hardness of 10.

Gold melts, diamond burns

Gold has a melting point of 1064°C. Diamond does not melt but burns around 800°C in the presence of oxygen. So gold could not melt and re-form diamond, which has a very stable crystal structure.

No chemical reaction possible between gold and carbon

There is no chemical pathway for gold to break down carbon sources like coal or graphite and reassemble the carbon into diamond crystals. The two substances are completely inert with no chemical reactivity.

In Summary, Gold Cannot Produce Diamond

The fundamental differences in the properties of gold and diamond mean that gold could not possibly produce or “mine” diamond. While both are precious, their formations are completely disconnected processes. Gold would need to extract diamond through basic mining, not generate it on its own.
