Granite is a general term applied to a broad range of stones composed primarily of feldspar, quartz, mica, and silica. This vast array of stone types are typically found in the continental plates of our planet’s crust and formed by heat and pressure.
Marble is formed when limestone is transformed by heat and extreme pressure. The veining that characterizes this stone are most often caused by mineral deposits found within the limestone, such as clay, silt, sand, iron oxide, and graphite.
Quartz, or “engineered stone” is a man-made product produced by factories most commonly in Germany, Israel, US, and Canada, though China and India are quickly becoming popular sources as well. It is composed of, on average, 93% quartz and 7% resin (epoxy, polyester resin, colouring)
