Be sure to double-check the spelling of the requested inscription before you pass it on to the engraver, and check it again when you receive it.
Igneous rocks form when magma or lava cools and hardens into a rock. Magma and lava are rocks that are so hot they move like a liquid. Magma is molten rock that is underground; lava is molten rock that is above the ground â and that is the only difference between them.A common igneous rock is granite.gneous rocks form when magma or lava cools and hardens into a rock.

Minerals can be formed from the intense heat and pressure found far beneath the earth's crust in the mantle, where molten rock flows as liquid magma. Silicates in the magma can form minerals such as hornblende and other igneous rocks as the magma cools. This process can take millions of years.Ninety-five percent of the earth's crust is formed from nine minerals, all of which are silicates, formed in this manner.inerals grouped together form rocks; the combination of minerals determines the type of rock formed. Since minerals are pure, they can all be written as a single chemical formula. A mineral can also contain some impurities and still retain its name, as long as the majority of the solid is a single mineral.
