What is magma? Magma is a super-hot viscous material that consists of molten and semi-molten rock that flows deep beneath the Earth’s surface. Depending on the chemical composition of the magma, there are three magma categories: basaltic magma, andesitic magma, and rhyolitic magma. There are different mechanisms for magma formation: partial melting, decompression melting, and flux-induced melting. When magma breaks through the earth’s surface, the magma that reaches the surfa

Fancy colored diamonds get their color from three main causes. Impurities, such as other chemical elements, in the diamond crystal structure, are the cause for fancy yellow and orange diamonds, as well as blue, violet, white and black diamonds. Lattice defects in the diamond structure lead to the fancy pink and red diamonds, as well as the fancy brown diamonds and purple diamonds. Radiation leads to the formation of fancy green diamonds. The rarest fancy-colored diamond is th

Diamonds are minerals composed of carbon that come from deep volcanic eruptions in the Earth's mantle and were formed billions of years ago.
