How Gemstones are Formed Minerals form under various conditions in the Earth's crust, the outermost layer of the Earth, with a depth of 8 to 40 km. Only two gemstone varieties (Peridot and the mighty diamond) form in the Earth's mantle, representing 84% of the Earth's volume. It consists mostly of molten rock called magma and is made up of 44.8% oxygen, 21.5% silicon,...
