What natural mineral is harder than a diamond?

Answer 1

There is none

Answer:

There are two naturally occurring materials harder than normal diamonds:

• The first, wurtzite boron nitride has a similar structure to diamond, but is made up of different atoms. It is formed during volcanic eruptions that produce very high temperatures and pressures. Wurtzide boron nitride can withstand 18% more stress than diamond,
• The second, lonsdaleite, or hexagonal diamond is made from carbon atoms just like diamond, but they are arranged in a different shape. Lonsdaleite is sometimes formed when meteorites containing graphite hit Earth. It is estimated that lonsdaleite 58% more stress than diamond..

Answer 2

The natural mineral harder than diamond is called lonsdaleite. It is a hexagonal allotrope of carbon and can be found in meteorites or in locations where high-energy events such as volcanic eruptions have occurred.
