How can you tell if a rock is a diamond?

The only hardness test that will identify a diamond is scratching corundum. Corundum, which includes all rubys and sapphires, is 9 on the hardiness scale. If your suspected diamond crystal can scratch corundum, then there is a good chance that you found a diamond. But NO OTHER HARDNESS TEST will identify a diamond.

igneous rockDiamond is a metamorphic mineral, as it forms under heat and pressure from solid-state processes. It forms independently of the igneous rock in which it is found, qualifying it as a type of xenocryst.

Is Diamond a product of metamorphism?

When rocks are heated up or put under a lot of pressure, they can change drastically. This is because the minerals that make up the rocks form only at certain temperatures and pressures. Graphite and diamond are two minerals that are both made entirely out of carbon. …
