Where do you have the best chance to find a natural diamond?

near the volcano

in the coal mine

in the silver mine

at the beach

It is sometimes mistakenly believed that diamonds are made from coals. High pressure and heat is required for the formation of diamonds from carbons, but these carbons are not the ones that form coal. Diamonds are formed deep under the surface and are brought up during outbreaks of volcanoes.
