The three basic geological types of stone are:
- Igneous Rocks (Granite) are mainly formed through molten magma. As the magma cools and condenses, it crystallizes forming the wide variety of colors and patterns.
- Metamorphic Rock (Marble) which is formed of calcium carbonate minerals. Over time, pressure and movement, it crystallizes forming the range of color, variety and texture.
- Sedimentary Rocks (Limestone): This type of stone is a collection of bottom rocks, fossils, sand and silt. They were banded through time from the heavy pressure of the stone above.
