Stone is a natural solid of one or many minerals. There are thousands of types of stone that have been quarried throughout the centuries. Quarries are located around the world.
The minerals in stone came from the same liquid and gas minerals that formed the earth. The earth developed as a massive body of gas and liquid minerals that slowly cooled and condensed into a solid core. Through pressure, the Earth’s crust began to form and heavy minerals were forced down to the core of the earth where they were trapped. As the crust got thicker, it squeezed around the inner core which create intense pressure and heat from within the earth. Crystals and other solid forms begin to grow from the mineral pressure pushed the solid minerals up to the Earth’s surface which formed colossal rock beds. It took up to one-hundred million years to form some of these beds. Many of the beds are now used as quarries where the stone is mined. Most of these minerals can be identified by their color, hardness and crystal formation. Crystal comes in a variety of shapes and sizes. The wide array of these minerals is often difficult to identify. Many stones look very similar to each other however they are all very different.
