Crystals and other solid forms began to grow from the mineral vapors that were being released. As the Earth's crust began to expand and erode, heat and 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.
Crystals come in a variety of shapes and sizes.
The wide array of these minerals are often difficult to identify. It is imperative to know the exact type of stone that is to be maintained. Stone is natural and may have adverse reactions to certain cleaning chemicals and procedures. Tiny sedimentary pieces broke off from these elements and accumulated to form rock beds. They were bonded through millions of years of heat and pressure.
